Can I Sell My Used Hardware?

If you are an IT Director or a CEO, chances are sometime in the near future you'll be looking to upgrade your hardware. It seems like an absolute headache from a financial perspective and from a logistics perspective. But it doesn't have to be as bad as you think. In fact, you can actually make money from your used hardware and you can even get your hardware removed for nothing.
Unfortunately many companies don't realize that they can get paid for their old hardware and invest that cash right back into their budget. Instead, they pay someone else to remove their hardware and they take a complete loss on it. This doesn't have to happen.
In fact, if you have enough hardware, there are some companies who will send a representative to pack it all up for you and take it all away. Then when the process is finished, you get paid by that company.

Computer Hardware Preventive Maintenance Software

Computers often break down at the worst of all times. These problems can be averted, or at least minimized with preventive maintenance. Several methods of keeping computer hardware in good working order deal with the external components of the computer, such as the keyboard and monitor. For example, it is important to keep the processor away from excess heat and moisture. There are also computer hardware preventive maintenance software programs that can help with the upkeep of other internal aspects of a computer.
While it is rare to find a CMMS that works on all of a computer’s hardware, many different programs can be utilized simultaneously. Some computers have periodic automatic updates available that can be downloaded and used to improve the computer’s performance. Other software programs, known as disk defragmenters, manage hard drive space so that software programs take less time to access. Programs known as hardware diagnostic utilities can check the computer’s hardware components and alert the user about any potential failures. Since some new hardware will not always work on all computers and could cause existing hardware to malfunction, it is important to have a CMMS program to ensure that the new hardware is compatible with existing hardware.
Antivirus programs are another important component of computer hardware preventive maintenance software. Computer viruses have become increasingly common in recent years and can render a good computer useless. While computer viruses mainly attack software programs, they can ruin hardware as well. Several manufacturers make reliable antivirus software. A couple of well-known companies are Norton and McAfee. As with much preventive maintenance software, these programs are usually available for a free trial period before the user must pay a subscription fee.
Computer hardware preventive maintenance software is necessary to keep computers in good working order. This software manages aspects of computer hardware that would be difficult and time-consuming for even the most computer savvy users.

Metric Cabinet Hardware

Are you tired of how your old cabinets look? Instead of hiring an interior designer, why not take a trip to the hardware store and look for the things you need to make the changes? You can start by buying some cans of paint, paintbrushes and rollers, pans, a few bottles of thinner, sandpaper, hinges and some cabinet hardware. Of course, you'll need proper tools like screwdrivers and maybe a drill if you plan to make some new holes in the wall.
But before you take a trip to the hardware store, make a few observations and plan ahead. Make sure that you know what you want to do and what kind of hardware you need. You can choose between a knob, which is something you use with one screw to mount as a handle of your cabinet, or a pull, for which you need two screws. You might want to take into consideration the design and the finishing of the hardware as well. You can choose from steel, brass, wooden, nickel, and many other kinds of finishing.Make sure you consider all the hardware you will need. You don't want to go all the way back to the hardware store just because you missed one screw or one knob, would you? Another aspect that is very important is taking the exact measurements of the hardware that you need. Surely you want the hardware you bought to fit in the existing hole of the cabinet. Though you may be prepared to drill a new hole just to accommodate your hardware, knowing the diameter and the depth of the existing hole and using it as a reference for the hardware you intend to purchase will save you a lot of time and hardship in the end.

Computer recycling

Introduction:
Over the years, tons of electronics equipment with hazardous materials have been thrown away with standard garbage. Over time, these materials leak out of the electronics causing damage to the environment. In order to try and reduce the threat, many local, state and federal governments are enacting legislation that requires proper disposal of old electronics.
Most computer equipment becomes outdated anywhere from one to five years after its purchase. This puts a burden on consumers to try and properly dispose of old equipment lying around the house. So, what are the different avenues that we can use to get rid of all this equipment properly?
Government Programs:
Several prominent states including California, Maine, Maryland and Washington have all enacted laws dealing with electronic waste. In addition to laws in these states, many cities and counties also have laws dictating the methods of electronic and computer disposal. It is important before throwing out any old computer parts or electronics to check with the appropriate government agencies to determine the proper methods.
The easiest method for determining the proper laws governing the region that you live in is to contact your local waste management company and local governments. Often times, government web sites will list the e-waste disposal rules under the terms "waste management", "recycling" or "environmental agency". Programs for disposal may be free or carry fees depending upon the item being turned in for disposal.
Manufacturer Recycling Programs:
Many of the larger computer and electronics companies have begun offering recycling programs. Often these programs will take older computer parts in exchange for credits towards the purchase of new equipment from the manufacturer. Other programs may be a simple pickup and recovery service that they charge a small fee for. Be sure to check all of the details regarding the program with the company before using them. Some of the companies will simply refer the customer to the state disposal due to government regulation.

Boot Order

Boot Order:
This is the most important setting for when you first build your computer. The boot order determines which devices the motherboard will look at for an operating system or installer. The options typically include Hard Drive, Optical Drive, Floppy Drive, Network and Other. The standard order at first startup is Floppy, Hard Drive, Optical Drive and Other. This will generally cause the system to find the hard drive first which will not have a functional operating system on the computer.
The proper sequence for the installation of a new operating system should be Floppy, Optical Drive, Hard Drive and Other. This allows the computer to but from the OS installation CD that has a bootable installer program on it. Once the hard drive has been formatted and the OS installed, it is important to then restore the boot order of the computer to the original of Floppy, Hard Drive, Optical Drive and Other.

Drive Settings:
The settings for the hard and optical drives that run off the ATA controllers is another area that users may need to alter. In most modern drives, the PIO and ATA modes are automatically detected and used. There are some cases that it may be necessary to set the controllers to a specific setting to properly function. This is usually only the case with older components.
To properly set the PIO and ATA modes for the drives, refer to the documentation from the manufacture of the hard or optical drive being installed. Once the settings are known from the manufacturer, the proper settings can be placed in the BIOS. Once again, this should only be done if there are problems with the computer when the AUTO settings are used.

Problems and Resetting the CMOS:
On some rare occasions, the computer system may not properly POST or boot. When this occurs, typically a series of beeps will be generated by the motherboard to indicate a diagnostic code. Pay close attention to the number and types of beeps and then refer to the motherboard manuals for what the codes mean. Generally when this occurs, it will be necessary to reset the BIOS by clearing the CMOS that stores the BIOS settings.
The actual procedure for clearing the CMOS is fairly straightforward, but check with the manual for the steps to double check. The first thing to do is power off the computer and unplug it. Let to computer rest for about 30 seconds. At this point, you need to find the reset jumper on the motherboard. This jumper is moved from the non-reset to reset position for a brief moment and returned back to its original position. Plug the power cord back in and reboot the computer. At this point, it should boot with the BIOS defaults allowing the settings to be redone.

Bios settings

Bios settings:
The BIOS or Basic Input/Output System is the basic controller that allows all of the components that make up a computer system to talk to one another. But in order for this to happen, there are a number of things that the BIOS needs to know how to do. This is why the settings within the BIOS are so critical to the operation of the computer system. For about 95% of the computer users out there, they will never need to adjust the BIOS settings of their computer. However, those who have chosen to build their own computer system will need to know how to modify the settings.
Some of the critical things one will need to know are the clock settings, memory timing, boot order and drive settings. Thankfully the computer BIOS has come a long way in the past ten years where many of these settings are automatic and very little needs to be adjusted.

How to Access the BIOS:
The method for accessing the BIOS is going to be dependent upon the manufacturer of the motherboard and the BIOS vender they have selected. The actual process to get to the BIOS is identical, just the key that is needed to be pressed will vary. It is important to have the user manual for the motherboard handy whenever changes will be made to the BIOS.
The first step is to look up what key needs to be pressed to enter the BIOS. Some of the common keys used to access the BIOS are F1, F2 and the Del key. Generally the motherboard will post this information when the computer first turns on, but it is best to look it up before hand. Next, power on the computer system and press the key to enter the BIOS after the beep for a clean POST is signaled. I will often press the key a couple times to make sure it registered. If the procedure has been done correctly, the BIOS screen should be displayed rather than the typical boot screen.

CPU Clock:
The very first setting that needs to be made in the BIOS is to adjust the motherboard to utilizing the proper clock settings for the CPU installed in the computer. Most modern BIOS vendors can detect the type of CPU and automatically set the proper timings. Refer to the documentation from the CPU and motherboard vendor for the proper settings.
The CPU speed is comprised of two numbers, a bus speed and a multiplier. The bus speed is the tricky part because vendors may have this setting done either at the natural clock rate or at the enhanced clock rate. The natural front side bus is the more common of the two. The multiplier is then used to determine the final clock speed based on the bus speed of the processor. Set this to the appropriate multiple for the final clock speed of the processor.
For an example, if you have an AMD Athlon XP 2500+ processor that has a CPU speed of 1.82GHz clock, the proper settings for the BIOS would be a bus speed of 166MHz and a multiplier of 11. (166MHz x 11 = 1.826 GHz)

Memory Timings:
The next aspect of the BIOS that needs adjusting is the memory timings. Typically it is not necessary for this to be done if the BIOS can detect the settings from the SPD on the memory modules. In fact, if the BIOS has a SPD setting for the memory, this should be used for the highest stability with the computer. Other than this, the memory bus is the setting you will likely need to set. Verifying that the memory bus is set to the appropriate speed for the memory. This may be listed as the actual MHZ speed rating or it may be a percentage of the bus speed. Check with your motherboard manual about the proper methods for setting the timings for memory.

Top 4 PC Technology of 2007

2006 was a really major year in terms of PC technology. 2007 on the other hand was more of an incremental year in terms of advancements. There weren't any earth shattering break throughs that really changed the market as a whole. Still, there were some significant technology items that were released. Here are some of the PC technologies released during 2007 that I feel are noteworthy.
ASUS Eee PC:
There has been lots of talk about low cost portable computers that can be easy to use and accessible. This has been the goal of the OLPC, but it has a number of issues around it. ASUS has finally delivered a product that seems to meet those goals. The Eee PC is an ultraportable notebook with solid state storage and very low cost that allows for general computing that is very easy to use. They do this with a variant of the Linux operating system, but the system can also be used with Windows XP if the user cares to go about buying and installing it. This is a great portable system for those who need to stay connected when traveling or just need a simple system for basic computing tasks but don't want a larger more expensive PC.
LED Backlighting:
Flat panel displays are ubiquitous for a personal computer now. They of course were developed for portable computers but have migrated into the desktop market. Now portable flat panels are getting a boost with a new form of lighting. Previous florescent lighting was used behind the LCD panel. This is general low power but it has harmful chemicals and a limited lifespan. LED lighting is now being implemented and providing a greater life span and larger power savings than even the florescent backlit displays. The displays can also be thinner thus taking up less space. Some forms of LED backlighting can even create greater color depth than before. It is now widely used in many laptops and even starting to make its way into desktop displays.
Intel P35 Chipset:
Intel's Core processor architecture has been a huge success and regained much of the market share they lost to AMD over the years. The P35 desktop chipset made a huge impact in the mainstream desktop market this year. The chipset offered a great level of performance and flexibility for Intel's processor lineup that was widely implemented by manufacturers. In fact, the performance from this chipset is so good, that it really overshadowed the X38 enthusiast chipset market. After all, why purchase a motherboard with a chipset that costs roughly twice as much for only a few additional features. About the only drawback to the P35 chipset is the lack of SLI support for NVIDIA graphics cards, but that only affects a small group of people.

Top PC Tech Blunders of 2007

Top PC Tech Blunders of 2007:
2007 seemed to be a year of minor improvements in the PC world along with a few ideas that were set to revolutionize the world. Of course, more than not a few of these ideas didn't catch on with the industry or with the computing public. With that said, let's take a look at some of the items from 2007 that I feel deserve the title of PC Blunders of 2007.

DDR3 Memory :
This isn't really so much a failure as a false start that happens to a lot of new technology. DDR3 is set to offer performance gains to computer memory that DDR2 supposedly can't offer. The problem is that the adoption of DDR3 has been slow and as a result the costs for the memory are extremely high. In fact, most of the early releases were only for performance memory. DDR2 memory modules are available that offer similar performance for as much as half of what the DDR3 costs. Similarly things happened when DDR2 and DDR were orginally introduced. Over time, DDR3 production and performance will improve such that the prices will fall and more people use it.

Hybrid Hard Drives:
Hybrid hard drives were set to change mobile computing by providing the large capacity of a traditional hard drive with the power savings and performance boost of solid state drives. Of course, these drives wouldn't really see these benefits without a compatible operating system in the form of Windows Vista with its SuperFetch, ReadyDrive and ReadyBoost features. This would allow the system to take commonly used files and put them in the faster flash than from the traditional drive. The end result was a drive that was more expensive than a traditional drive but really didn't have all that much of a performance boost. It did save some battery life, but most solid state drives look to be the more popular and expensive alternative.

AMD Quad FX Platform:
Tecnically the AMD Quad FX platform was launched at the end of 2006, but 2007 was when products really became available. The design combined two new AMD Athlon 64 FX dual core processors on a single board to provide four cores to provide extreme performance. While it did boost performance for a limited number of applications, the general consumer was left looking at the cost. The chips weren't compatible with the rest of the AMD processor lineup and were extremely expensive. This resulted in a platform that was ridiculously expensive yet didn't give much of a performance boost for the average consumers uses. Needless to say it didn't take off and AMD officially dropped the product line at the end of 2007.

som small tips

Should I turn my computer/monitor off?
Turning a device on/off causes thermal stress. Leaving it on causes wear and tear (even on non moving parts). The only thing you shouldn't do is quickly power cycle the computer. If you turn it on/off, leave it that way for at least a few seconds. Other than that, it's up to you.
What should I upgrade my omputer first?
This is highly debatable. In general, if you buy from a good, self-respecting company, any additional cooling requirements would have been taken care of before your system was delivered to you.
I'm responsible for PC maintenance at my site, and I don't worry about additional cooling in any of the pre-packaged systems we receive. All rebuilt and/or upgraded 486-33 (or higher) systems do, however, receive additional cooling because older cases may not provide adequate ventilation for today's technology. Additional cooling on the infamously-hot Pentium (586) is always added.
So, do YOU need a CPU fan in YOUR system? Probably not for "ready to run out of the box systems." If you are _REALLY_ worried that your system is suffering from too much heat, consult with a reputable service center. They will not only answer your questions, but they can also install any additional cooling systems that may be needed. A good rule of thumb, though - "don't try to fix what isn't broken."In other words, if your system is working, don't look for trouble.

Right processor

How to pick the right processor?
This is a hard question. You have tradeoffs between price,performance, compatibility, upgradebility, and power consumption. As a desktop unit owner, you probably have less concerns about power, but as a laptop owner, this is very important.
The frequency of the CPU defines how fast its internal clock runs. This defines how fast instructions are executed. In many ways, this is meaningless, because a RISC machine (MIPS) running at 100MHz may in reality be slower than a 50Mhz i486 because a RISC system must execute more instructions to perform the same function (in some cases). Even when comparing processors in the same family, this info can be misleading. For example, an Intel486-25 is faster than an AMD386-40, since the 486 has microarchitectural advancements over the 386. The same can be said for the Pentium, where a 66Mhz Pentium is twice as fast as a 66MHz 486.
For compatibility, keep in mind that the Intel parts are the basis for all of these processors. Therefore you always run the risk that an imitator's part may not be compatible. AMD [486] chips are compatible because they are copied. For some of you, these factors may be important.
As far as upgradability goes, this depends on both your motherboard and the processor. If you purchase a 486DX, then you can upgrade to a DX2 and double your internal clock simply by buying an overdrive chip if your motherboard has the ZIF socket. If it doesn't then you canreplace the CPU with a DX2. Many new 486 motherboards containoverdrive sockets for the Pentium chip that is pin compatible.

Types of Window Hardware

Types of Window Hardware:

You will find out that there are a variety of materials available for you to choose from when it comes to window hardware. There are lot of options, however, you will want to keep in mind that there are some that are better for energy efficiency and design. You will find that there may be a personal preference that you have and you may want to see what is best for your family and for your home.

One type of hardware is the wood type. Wood is the most common material used when it comes to installing any window. The wood happens to be the easiest material to work with regardless if you are professional or an amateur. You will also be able to find some custom work. You will find that there are details that you can put into the designs and you’ll find a wide range of things as for painting and staining. You will find that there are also materials that are energy efficient too.

The only thing that you will find is that there is some maintenance that is required. You will need to keep up the paint or stain so that you can properly keep the wood preserved. You will find that the paint peeling will cause wood to rot. You will find that there is some regular maintenance.

Then there is steel hardware for windows. Steel is most often found in some of the older homes and basement for the windows. It is rarely used because heat can escape through the frame of the windows. You will find that there are regular maintenance that is needed. You will find that you will need to repaint, however, if you do not, it will rust. The steel material version is very durable and will withhold a serious change in the weather.

You could always go with aluminum window hardware and that is just as durable as steel. You will also want to think about the energy and how efficient it could be. You will want to make sure that you think about all the heat that you would loose. There is some benefits to using this type of material and that is that it doesn’t require much maintenance. The color of the metal is baked on and it also comes in a variety of colors and you will not have to repaint.

Keep in mind that there is also vinyl. This is an inexpensive and durable material for windows. You will find that it is great for energy saving and there is no maintained. You don’t’ have to paint, and you don’t have to worry about any paint flaking. You will be able to get many window color choices, however, you don’t ever have to worry about the flaking of paint. You will love vinyl because it makes things seem so easy, especially when it comes to maintenance.

You will also want to think about fiberglass window hardware, however, you will want to consider all of the options that you have. This will help you to make a lot of improvements to the home, however, you need to think about the pros and cons of each different kind.

Upgrade Your Hardware

Should You Upgrade Your Hardware PC?

What if you found that your computer is out of date? You probably want to upgrade your computer since you have no choice to do so. Your works depend on your hardware computer upgrade. That’s how you going to have a good result.

But before you make any further step, try to learn about your computer. Search all options and ask for advice. Only after this you can go and buy a new component. It’s also useful to check if you really need an upgrade.

Sure, it’s not funny if you keep your old computer but you still loose data when you do your works. Its just a matter of time before you experience a hard drive problem when you still using your old computer. You dont want to loose your data, right? Of course most people only think of backing up their data after they experience a problem. Don't set yourself up for a data loss disaster. Check what hardware you need for your computer.

If you have problem with your hard disk, such as crash when you do your work, better you have it renewed. Most people upgrade their hard disk to increase the size so that they can use it for games, movies and playing a lot of music. A 20 GB hard drive is sufficient to keep new office and internet applications, and all your files and data. A medium sized hard drive would be around 40 GB and the maximum would be around 60 – 80 GB.

You can choose which perfect for your work. Of course the price is also depending on the capacity of your hard disk. If you are a gamer, you may want to have high capacity hard disk such as that 60-80 GB. But if you just used it for your writing, a 20 GB is more than enough.

Another hardware you may need to upgrade is the RAM or Random Access Memory. This memory keeps data that is being worked on now and may or may not be transferred to the hard drive that represents the long-term memory of the computer. Current processors can perform an enormous number of operations per second. Almost all computer have 64 MB RAM and often 128 MB. If you want to run newer applications on your PC then you must upgrade to 128/256 MB RAM. A lot of people who upgrade from 98 to Win 2000 discover that their computers lock up very often. This is because they don't have enough RAM.

So, those are only some part of hardware you might want to upgrade. There are others such as motherboard, CPU or port which you can upgrade. Your action depend on your need.

Hard Drive Data Recovery

Hard Drive Data Recovery:
Data recovery can be tedious. The good news is data recovery, more often than not, is still possible. Data recovery can be done in either two ways: by using data recovery software or data recovery services. Data recovery software can help you revive the data which you thought was lost. However, data recovery services can do more than that.

So what exactly is data recovery? Data recovery, according to the word sleuths and data recovery experts, is the process of salvaging deleted or inaccessible data stored on damaged media like magnetic disks and computer hard drives, optical devices, and tape cartridges. Many data recovery software programs and data recovery services are designed to help users retrieve their files at the event of a computer crash or viral infection.

How does data recovery work? The first step of the process of data recovery service usually involves evaluation to determine the extent of the data lost. After the prognosis, the data recovery experts and technicians would then proceed in “cloning” or copying the media into their systems. The actual data recovery process occurs when the technicians secure and extract the data from the copy of the damaged media.

Hardware and software teams A damaged media has the data locked within it and it is the job of highly experienced hardware and software engineers to unlock it. These two teams of data recovery experts work very closely together throughout the project, combining all their experiences in their respective fields to solve the problem quickly and surely.

For safety measures, hardware engineers access as much of the disk as they can to produce the copy which they then share with the software specialists. The bulk of the data recovery process lies on the software team as they are the ones who do the actual extraction using complicated software programs designed especially for data recovery work. The ensuing data are then filed and written onto a new, undamaged media.

Before engaging a hard drive recovery service to attempt data recovery, it pays to know what a hard drive and hard drive failure are. A hard drive is a stack of discs coated with thin layers of substrate and magnetic material. Hovering above the disc is the drive head. The discs create a slight breeze as they spin, creating a cushion of air for the head. The drive head, as a rule, never touches the discs unless something happens to that cushion of air beneath it. If however, the head touches the discs, it will drop through the magnetic layers and cut slashes into the surface of the discs. It grinds through the aluminum substrate and sprays dust from all three layers all over the discs. The result is hard drive failure.

Utilizing data recovery services from data recovery experts usually comes as a last resort. But they do not come cheap. Data recovery software like, say Symantec’s, could cost something like $39.95. A data recovery expert could charge from $250 to $3,500 on their data recovery services.

Each data recovery service has a unique approach in solving the data recovery problem. But usually, the priority is to get the damaged drive running again. However, data recovery services cannot perform miracles. A massive head crash in the drive usually mean it’s gone for good.

various tips

Elements to make an PC:
There are 4 elements that make up a personal computer system: the user, software, hardware and the electricity all working together for the whole system. Each of these elements is essential to the system itself.
The user is the person’s who perform the task using the computer system. The nature of the task depends upon the application program or software that is needed to perform the task. The software that the user used requires certain hardware components to function properly.
The hardwares of the personal computer system are made up of its equipment that are usually connected (the computer, monitor, printer and so on). It is defined as hardwares because you can physically touch these components. The programs are called softwares since their function can only be used when the computer is turn ON. Software is a set of coded instructions that the computer uses in order to carry out the user's tasks.
The user can only use the computer when it is turned ON. Without any electrical power to run through the personal computer system, it will not function. The ability of the personal computer system to control its components is through a series of on/off signals.
Here is how it works, when a user tries to type a document or a letter using his/her personal computer. The first thing the user do is to turn ON the power for the computer. Choosing a Word Processor software in order to write the document. The user uses the hardware such as the keyboard to write the content of the document; the typed document is then displayed onto the monitor screen. After the user finished writing his/her document. The user will use the software to instruct the printer to print the document. The software works together with the hardware components (the keyboard, monitor and printer) to accomplish the task that the user requested.
All of the four elements: the electrical power, hardware, software and the user work together to make up a personal computer system.

PC crash & how to fix

3 Causes of PC Crash and How to Fix Them:

PC Crashes are caused mainly of the following:

1. Inappropriate Software drivers for a new hardware or inappropriate hardware
2. Virus attacking the Windows operating system
3. Corrupted Windows Registry

If you have recently installed a new device, for example, a new TV PCI adapter, check to see if the software drivers you have installed are appropriate to your particular hardware configuration. You will be able to tell if it is the one causing the crash if after you remove the new hardware physically, your computer stops crashing. To resolve this, you have to check with the hardware vendor what appropriate software driver for your PC is. They could have an updated driver for you to download to fix a bug to the software driver.

A virus, spyware, or trojan attack can also be the cause of a computer crash. These viruses commonly attack the Windows Operating System core files like the ntdll.dll and ntoskrnl.exe files. Viruses come from clicking on an unknown link or opening an attachment from an e-mail. Always keep your anti-virus definition files updated to be able to detect and clean the latest PC virus infections.

Windows Registry corruption is also a common cause of PC crash. Frequent installation and un-installation of programs and corrupted software drivers lead to corrupted Windows Registry. The Windows registry, stored on your PC in several files, records the relationships or links between hardware, memory space, and addressing. If these links are broken, your PC will malfunction, hang or crash. A good Registry Cleaner tool is needed to automatically restore these links.

Manual registry cleaning using regedit is not recommended since setting those data type and values manually is also one of the main causes of invalid links in the registry.

Recommendations to fix and prevent computer crashes:

• Install new hardware with the latest software drivers from the hardware vendor. Check hardware compatibility with your existing PC.
• Always keep updated on Microsoft Patches to prevent security vulnerability attacks on the Windows core operating system.
• Run Registry Cleaner tool regularly, at least once a week, to clean any errors on the registry.
• Always keep your Spyware removal tool and anti-virus software updated of latest spyware and virus definitions. Regularly scan your PC and remove spywares and viruses.

DVD Burning

DVD Burning Easier:
The hardware necessary to burn DVDs has become extremely popular over the past few years. Years ago this type of hardware would require an upgrade on the standard computer, now they are becoming standard equipment. With the addition of a DVD burner, computer users have many more options available from burning DVDs to watching them. As a result the entertainment value of the computer has greatly increased.
There are two necessary components in order to copy a DVD, the hardware and software. The hardware is a DVD burner which can be internal or external. It is now very common to find an internal DVD burner on most new computers. For users with older computers an external DVD burner can be purchased through most office supply stores and just about all computer stores. External DVD hardware is relatively inexpensive and is a somewhat small unit that would be placed next to the user's computer and is usually connected via a USB cable and port.
As far as the software is concerned, users have many choices depending on what type of DVD they want to copy. DVD copy software can also be purchased online or your local computer store, and in many cases the DVD burner hardware will also include the necessary software. However, if the user wants to make backup copies of DVD movies, they will, more than likely have to purchase this type of software online.
There are several benefits of owning DVD burner hardware. It's great to be able to burn a DVD of your child's latest karate tournament or big game and send a copy to close relatives and keep in touch. With DVD burner hardware you can make a backup copy of a DVD that you don't want to loose. Another benefit is that DVD burners are generally easy to use.
If you have been putting off the purchase of DVD burner hardware, with prices decreasing, now may be the perfect time to upgrade to a new computer with an internal DVD burner or to invest in an external DVD burner. Once you see how easy it can be to copy DVDs you may just become the DVD copy expert in your family.

Computer Drivers

Computer Drivers - What Are They?
There are many opinions about which computer system is best, they are based mainly upon the system that the person is most acustom to. People find themselves using computers more and more every day. So it is a good idea to know how they work and the different parts that make them up. For other devices, you may need to load a new driver or drivers when you connect the device to your computer.

Hardware:
The physical elements of a computer is its hardware, they are generally divided into the central processing unit (CPU), main memory, also known as RAM and the peripherals. Hardware drivers are hidden from you. This makes them hard to find and even harder to get information on. Vista is coming up but at this time windows XP is a main operating system, and hackers are targeting it, so make sure you have a hardware firewall in place then security won't be a major issue. Also make sure that your computer's hardware drivers are up to date. As a result, many computer and server users do not keep current with the latest hardware upgrades and subsequently experience problems that could have been avoided.
Some upgrades are built to increase a program's compatibility. There is a need for a computer programs to provide autonomic upgrade maintenance of computer hardware and operating systems. When using other devices, you may need to load a new driver when you connect the device to your computer. The driver, therefore will accepts generic commands from a program and then translates them into specialized commands for the devices modem. A working computer requires both hardware and software. Those who keep up with the upgrades find themselve spending a large amount of their time doing so. You might want to decide how much time and upgrades you want to put in.

Hardware Prevent

Computer Hardware Preventive Maintenance Software:
Computers often break down at the worst of all times. These problems can be averted, or at least minimized with preventive maintenance. Several methods of keeping computer hardware in good working order deal with the external components of the computer, such as the keyboard and monitor. For example, it is important to keep the processor away from excess heat and moisture. There are also computer hardware preventive maintenance software programs that can help with the upkeep of other internal aspects of a computer.
While it is rare to find a CMMS that works on all of a computer’s hardware, many different programs can be utilized simultaneously. Some computers have periodic automatic updates available that can be downloaded and used to improve the computer’s performance. Other software programs, known as disk defragmenters, manage hard drive space so that software programs take less time to access. Programs known as hardware diagnostic utilities can check the computer’s hardware components and alert the user about any potential failures. Since some new hardware will not always work on all computers and could cause existing hardware to malfunction, it is important to have a CMMS program to ensure that the new hardware is compatible with existing hardware.
Antivirus programs are another important component of computer hardware preventive maintenance software. Computer viruses have become increasingly common in recent years and can render a good computer useless. While computer viruses mainly attack software programs, they can ruin hardware as well. Several manufacturers make reliable antivirus software. A couple of well-known companies are Norton and McAfee. As with much preventive maintenance software, these programs are usually available for a free trial period before the user must pay a subscription fee.
Computer hardware preventive maintenance software is necessary to keep computers in good working order. This software manages aspects of computer hardware that would be difficult and time-consuming for even the most computer savvy users.

Hold of Good Hardware

Getting a Hold of Good Hardware:
These days we look at the word "hardware" and think, "computers". If you are one of those people, let me tell you that this article on hardware talks about purchasing pipes, plumbing, wires, power tools and so on.
If you are looking for new pipes for your bathroom, don't just buy the first set of pipes that you see in a hardware store window. Remember, these are not clothes you are buying. Clothes can be replaced for a relatively low expense. However, even if just one pipe decides to burst, you would definitely have to spend a fortune on plumbing. Wouldn't it be better to save yourself that money and buy yourself a set of pipes that have a greater staying power instead?
Durability and usability are two factors that are of the utmost importance when it comes to hardware products. So when it comes to even a measly difference of rates, be more partial to a hardware store that charges more. At least until you are absolutely certain that the cheaper hardware store owner is offering a product of equally superior quality.
The best thing about going to an Acme hardware store, or to some other hardware store that has a good reputation, is that you are assured of the quality of the product you are buying. I'm sure you don't want to have to return to the hardware store again and again simply because the things that you bought to plug the leak in your room or below the basin, were not up to the mark.
Whenever a person goes shopping, he or she looks around for products that fulfill some specific basic requirements. The same concept holds true whether you are shopping at an Acme hardware store, or simply at the unnamed hardware store near the bus station.

Hardware v/s software

PC Computer Software - How Is It Different From Hardware?
The PC software methods can include applications, operating systems, and device drivers for installed hardware components. The main components of information systems are computer hardware and software, databases, telecommunications systems, human resources, and procedures. It consists of the programs that instruct the hardware to perform tasks. A computer's operating system are the systems that allows all the hardware and components to work together. PC software is often more expensive than the computer hardware that it runs on. Device drivers are a special type that lets the operating system and other programs work with your computer's hardware. Hardware is the computer's physical electronic and mechanical parts. If your PC is not working properly while you are working on it, it could be a problem with device drivers, hardware or software.
Software is the entire set of programs, procedures, and routines associated with the operation of a computer system. PC software falls into two broad classes: system software and application software. The main system is known as the operating system. There are many of software updates. The free software often leads to poor quality because of the human nature to settle for something that cost less.
Often, upgraded versions of software are built to fix some problem that the previous upgrade introduced. Some upgrades add features that users were requesting or that a software developer thought would be desirable. With the growth of Internet access, many software applications and operating systems include an automatic update tool that will check your software manufacturer's Internet site to see if the current version of the software application running on a your system is the latest version. If not, a mechanism exists for downloading and installing the latest version of the software to your system. Do to some of the sizes of the software packages many of these downloads take an unreasonable amount of time if you are using a standard dial-up Internet connection.

Hard Disk Drive Maintenance

Hard Disk Drive Maintenance Procedures:
You want your computer to last. cleaned out the mouse, kept out the dust... but that's all about 'hardware' . We should be confident in keeping the software in good running order.

We are lucky for, Microsoft provides a couple of tools to help keep our hard drive and the programs on it healthy and happy (and running longer) as well. The best part is (if we have Windows), they're already loaded on our machine! We will be going through few of them.

The first thing we need to do is locate them on your hard drive. Right-click the Start button and select Open, then double-click Programs, then Accessories. You should see a folder called System Tools. Double-click System Tools to discover a bunch of stuff we never them.

The first one we're going to look at is the Disk Defragmenter. What's a defragmenter? programs save files to the hard drive, they try to grab the next available space (this is simplified, of course) to where we save the last time. If the space is 'right next door', it's called 'contiguous' space. That's good space, because when the program is reading the hard drive, it just goes 1...2...3..., everything is in order.

However, if the space next door is taken, it will have to search around and put your files somewhere else. After a while,it is trying to read it back in as 1...78...32...that can take longer and can result in Windows losing track of where the parts of a file are.

In order to put everything back in order, you must defragment the disk, which takes all the pieces of all the files and puts them in contiguous space. I defrag , but some recommend it be done at least weekly.

To run the Defragmenter, double-click the icon, select the drive you want (your hard drive is usually 'C') and click OK.Then go make a sandwich, as this will take some time. Windows will read all the programs on your hard drive and put them together with all other parts of that program, freeing up space and making your machine run better.

We've freed up some space now, but we want more. Where can we get it? One place is by deleting all the temporary files that Windows has kept for you. Double-click the Disk Cleanup icon, select your hard drive again, and a popup box will appear showing things like Temporary Files, Recycle Bin, all the places that Windows knows of files that are not needed. Select the ones you want and click OK. They're gone, and you have a lot more space for those new downloads you want.

If we are constantly low on hard drive space, it might be best to do this before you defragment the disk, then you can free up all that used space as one big block.

The final program is called ScanDisk...it's the one that comes on when you boot up after failing to shut down the computer correctly (if you should have a lock-up or lose power, for example). Double-click the ScanDisk icon and a box will pop up and give you a number of choices. Select your hard drive, and then either Standard or Throrough.

A Standard scan will check your files and folders to make sure everything is 'pointed' in the right place. It doesn't take long to do. However, before you run it, it's a good idea to close every program you can, because if these programs write to the hard drive while Scandisk is running, ScanDisk may have to start over...it can be pretty frustrating if that happens.

If you've closed everything and it still keeps restarting, it might be an indication that a program is hung up... shut down the machine, restart, and try it again.

A Throrough scan performs a Standard scan, but then checks the hard drive itself for errors (like a 'spot' that won't record data correctly), and marks them 'off limits' to the computer so data does not get lost there. All hard drives develop 'bad spots', so it's a good idea to run a throrough scan at least monthly to catch them.

If we really want to play around, there's also a 'Task Scheduler' which will allow you to automate this process,this process is some what typical, but some people find that it easier to perform preventive maintenance if they set reminders for themselves.

India putting as "A"

Hard drives:
High-tec innovations are putting INDIA on the "A" list:
Super computers and india had never really been synonymous. The best the country could offer till now was the centre for development of advanced computing's PARAM series, of which the fastest was padma with the speed of one teraflop or one trillion operations per second.Nevertheless, it still ranked a lonely 171 on the top 500 list of the world's fastest computer's in 2003.Recently,how ever, the TATA -Owned computational research laboratories in pune has installed a super computer system named Eka that managed to achieve a speed of 117.9 teraflops.

This makes it not only the fourth fastest machine of its kind in the world but the fastest one in Asia.built in a little less than 2 years at a cost of approxmaitly $30 million.Eka has the distinction of being the first supercomputer to have been developed totally by a corporation without any government help,using mainly off-the shelf components.Given its spectaculear speed.it can be used for a variety of tasks-including long-range weather forecasting ,financial modelling ,data mining, animation, drug discovery and computing intensive task like oil and gas exploration.Its operation time can also be sold commerically. Market research firms forecast that spending on the high performance computing market will rise from over $10 billion worldwide in 2006 to $14.3 billion by 2010.

The development also propels INDIA in to a different leaguealtogether. Far from being labelled "CYBER COOLIES" of the IT world who carry out only back end work in "BPO's" call centres and out sourcing offices ,it demonstrate's how the nation is steadily beginning to climb up the value chain. What's more,its happening in other fields too.For example the country's largest CAR maker Maruthi also revealed its plans for unveiling A-star, its brand new concept car a prototype which basically showcases innovation in styling,engineering and technology.

After being displayed at the ninth edition of Auto expo in the capital in janaury 2008,its expected to make the rounds in all major expos across the world before going in to production. That's not only a long way off from the day's of being dumped with obsolete models of ambassadors and fiats but vastly different from India being perceived as a srcewdriver nation with a cheap work force assembling auto mobiles originally designed by others. These are great trends gaining momentum by the day.

High-End Workstation Works Hard, Plays Hard:
It is a PC that is primarily intended for game designers, videographers and other high-end users, with powerful components and classy black styling.

The D10 runs Windows Vista and has up to 750 gigabytes of hard-drive space. It can also hold up to 64 gigabytes of RAM — an impressive number for even high-end gaming machines — and has a powerful Nvidia Quadro graphics card and an optional Blu-ray disc burner.

The D10, starting at about $1,740, is also Energy Star compliant, which means it runs at 80 percent energy efficiency and is cooled by an almost silent internal duct system. Special front and side service latches pop open for easy upgrades, and the built-in ThinkVantage system recovery and security software ensures that data does not go missing.
This powerful machine might look as if it belongs under a desk at a big corporation, but don’t let the lack of flames and other design accouterments fool you — if need be, this PC can also play hard.

internal view

This is the inner view of an cpu.Her we can see RAM, SATA Hard disk,LG super multi drive,
cpu fans,etc. These devices are connected to motherboard through various buses and power cables.

Buses:
In computer architecture, a bus is a subsystem that transfers data between computer components inside a computer or between computers. Unlike a point-to-point connection, a bus can logically connect several peripherals over the same set of wires. Each bus defines its set of connectors to physically plug devices, cards or cables together.
Early computer buses were literally parallel electrical buses with multiple connections, but the term is now used for any physical arrangement that provides the same logical functionality as a parallel electrical bus. Modern computer buses can use both parallel and bit-serial connections, and can be wired in either a multidrop (electrical parallel) or daisy chain topology, or connected by switched hubs, as in the case of USB.

RAM & ROM

Random access memory (RAM):
Random access memory (usually known by its acronym, RAM) is a type of computer data storage. It today takes the form of integrated circuits that allow the stored data to be accessed in any order, i.e. at random. The word random thus refers to the fact that any piece of data can be returned in a constant time, regardless of its physical location and whether or not it is related to the previous piece of data.
This contrasts with storage mechanisms such as tapes, magnetic discs and optical discs, which rely on the physical movement of the recording medium or a reading head. In these devices, the movement takes longer than the data transfer, and the retrieval time varies depending on the physical location of the next item.
The word RAM is mostly associated with volatile types of memory, where the information is lost when power is switched off. However, many other types of memory are RAM as well (i.e. Random Access Memory), including most types of ROM and a kind of flash memory called NOR-Flash.

ROM :
It is an abbreviation and name that may refer to:
In Computers and Mathematics:
* Read-only memory, a class of storage media used in computers and other electronic devices. This tells the computer how to load the operating system.
* Mac computers typically included Old World ROM or New World ROM
* ROM image, a computer file which contains a copy of the data from a read-only memory chip.
A ROM image, or simply ROM, is a computer file which contains a copy of the data from a read-only memory chip, often from a video game cartridge, a computer's firmware, or from an arcade game's main board. The term is frequently used in the context of emulation, whereby older games or computer firmware are copied to ROM files on modern computers and can, using a piece of software known as an emulator, be run on the newer computer.
ROM images are also used when developing for embedded computers. Software which is being developed for embedded computers is often written to ROM files for testing on a standard computer before it is written to a ROM chip for use in the embedded system.
* ROM (MUD), a popular MUD codebase
* Random oracle, as in "random oracle model", a mathematical abstraction used in cryptographic proofs
* ROM cartridges, a portable form of read-only memory
* Rough Order of Magnitude (ROM)- Very early cost estimate of a project.

Motherboard

Motherboard:
The motherboard is the "heart" of the computer, through which all other components interface.
* Central processing unit (CPU) - Performs most of the calculations which enable a computer to function, sometimes referred to as the "brain" of the computer.
* Computer fan - Used to lower the temperature of the computer; a fan is almost always attached to the CPU, and the computer case will generally have several fans to maintain a constant airflow. Liquid cooling can also be used to cool a computer, though it focuses more on individual parts rather than the overall temperature inside the chassis.
* Random Access Memory (RAM) - Fast-access memory that is cleared when the computer is powered-down. RAM attaches directly to the motherboard, and is used to store programs that are currently running.
* Firmware is loaded from the Read only memory ROM run from the Basic Input-Output System (BIOS) or in newer systems Extensible Firmware Interface (EFI) compliant
* Internal Buses - Connections to various internal devices.
Power supply:
A case that holds a transformer, voltage control, and (usually) a cooling fan, and supplies power to run the rest of the computer.
Storage controllers:
Controllers for hard disk, CD-ROM and other drives like internal Zip and Jaz conventionally for a PC are IDE/ATA; the controllers sit directly on the motherboard (on-board) or on expansion cards, such as a Disk array controller. IDE is usually integrated, unlike SCSI which is found in most servers. The floppy drive interface is a legacy MFM interface which is now slowly disappearing. All these interfaces are gradually being phased out to be replaced by SATA and SAS.
Video display controller:
Produces the output for the computer display. This will either be built into the motherboard or attached in its own separate slot (PCI, PCI-E or AGP), in the form of a Graphics Card.

CPU(Central processing unit):
A central processing unit (CPU), or sometimes just processor, is a description of a certain class of logic machines that can execute computer programs. This broad definition can easily be applied to many early computers that existed long before the term "CPU" ever came into widespread usage. However, the term itself and its initialism have been in use in the computer industry at least since the early 1960s (Weik 1961). The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation has remained much the same.
Early CPUs were custom-designed as a part of a larger, usually one-of-a-kind, computer. However, this costly method of designing custom CPUs for a particular application has largely given way to the development of mass-produced processors that are suited for one or many purposes. This standardization trend generally began in the era of discrete transistor mainframes and minicomputers and has rapidly accelerated with the popularization of the integrated circuit (IC). The IC has allowed increasingly complex CPUs to be designed and manufactured in very small spaces (on the order of millimeters). Both the miniaturization and standardization of CPUs have increased the presence of these digital devices in modern life far beyond the limited application of dedicated computing machines. Modern microprocessors appear in everything from automobiles to cell phones to children's toys.
