Why does a computer need CMOS?
because its easier to change the setup values
I am assuming you mean the CMOS battery. If this is the case the answer is no you do not need a CMOS in the basic sense of what it actually does. However, I know that there are board out there that probably would not function without one.
The only thing I have to ask, is that even if you could boot without the CMOS why would you want to? It is in charge of maintaining the correct time, among many other noncritical and fluctuating data, too unimportant to save to actual hard disk. Without it you would have to boot fresh each time. There would be no advantage to removing the battery.
If you are asking because you don't want important information to carry on, the CMOS would is the least of your worries. However, possible you meant to ask if a computer needs a BIOS. If that was the case, again no but why would you want to.
The BIOS might seem to take a long time to get through to your Operating System but it is what starts your OS and recovers it. As everyone know there are multiple systems out there- windows, mac- linux. Your BIOS is outside, for the most part, of all of these OS's. It is the gatekeeper to all information on your computer. It is in zen with your computer, no matter what happens to your OS's your BIOS will be there to make it right. As it's acronym says it is the Basic Input and Output System, meaning without anything else you can at least input data into your Blue Screen. It is what will open the CD drive so you can insert that recovery CD in the time of need. Any logical person would not put everything they have on a ship then throw off all the life boats. So yes you could do without a BIOS, but when running any modern operating system you should wait the extra time so you don't get a massive paperweight in place of a computer.
Those are my thoughts.
How do you go into Toshiba Tecra 8000 laptop setup menu with Windows ME?
To enter the BIOS on a Tecra, hit the ESC key as soon as you see the Toshiba flashscreen in red. When prompted, hit the F1 key.
What is the difference between CDs and DVDs?
CDs have a storage capacity of around 700MB whereas standard DVDs can store 6 times as much information - around 4.5 GB - or even more on double layered DVDs. This means that video content (around 3GB for a movie) will fit onto a DVD but would be too large for a CD.

What happens when you format your pen drive?
Formatting your memory stick deletes all information stored on it. Like a Master Reset. But also it creates the Original Files you got when you first got your psp. (GAMES/MUSIC/VIDEO/ MS_ROOT/ PHOTO)
No it would not, it could actually slow the speed down of the second computer. It could depend on the speed coming in to the house, and the quality of the router you are using, but it will most likely slow down by a few MbPS.
AnswerI disagree with the first answer. I think that sending the second computer to the cable modem via a router and ethernet cable should improve its speed. Now if that improved performance and convenience mean that both computers are online at the same time more frequently, then that might affect the performance of both. But when used one at a time, I would expect to see no difference for the first, and an improvement for the second.Difference between short term and long term schedular in operating system?
long term schedular select job from job queue and send to ready queue while short term schedular select job from ready queue and send for execution
How does printer sense paper HP Deskjet?

Can you replace a graphics chip with a graphics card?
If you mean you want to use a graphic card and not your onboard graphics , then yes.
But you don't touch the chip, when you install a card into the slot, and remove your onboard graphic drivers, then install your card drivers, then you will be using the card.
Most cards will tell you how to install the card and when to uninstall drivers and when to install them.
Almost all motherboards have a slot that can run a graphics card. Just make sure
its better than your onboard or you will be wasting your time.
What are output devices and explain their functions also?
output devices are those who diplay or give you your results for any entered data.
e.g
Monitors
LCDs
Printers
Plotters
Monitors and LCDs give soft copy of your results And the other two give hard copy on papper or other printing meterials

What is IRQL Not LESS Or Equal blue screen error?
The IRQL_NOT_LESS_OR_EQUAL bug check has a value of 0x0000000A. This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above. == The following parameters are displayed on the blue screen. {| ! Parameter ! Description | 1 Memory referenced 2 IRQL at time of reference 3 0: Read 1: Write
4 Address which referenced memory == This bug check is issued if paged memory (or invalid memory) is accessed when the IRQL is too high. The error that generates this bug check usually occurs after the installation of a faulty device driver, system service, or BIOS. If you encounter bug check 0xA while upgrading to a later version of Windows, this error might be caused by a device driver, a system service, a virus scanner, or a backup tool that is incompatible with the new version. == If a kernel debugger is available, obtain a stack trace. To resolve an error caused by a faulty device driver, system service, or BIOS # Restart your computer. # Press F8 at the character-based menu that displays the operating system choices. # Select the Last Known Good Configuration option from the Windows Advanced Optionsmenu. This option is most effective when only one driver or service is added at a time. To resolve an error caused by an incompatible device driver, system service, virus scanner, or backup tool # Check the System Log in Event Viewer for error messages that might identify the device or driver that caused the error. # Try disabling memory caching of the BIOS. # Run the hardware diagnostics supplied by the system manufacturer, especially the memory scanner. For details on these procedures, see the owner's manual for your computer. # Make sure the latest Service Pack is installed. # If your system has small computer system interface (SCSI) adapters, contact the adapter manufacturer to obtain updated Windows drivers. Try disabling sync negotiation in the SCSI BIOS, checking the cabling and the SCSI IDs of each device, and confirming proper termination. # For integrated device electronics (IDE) devices, define the onboard IDE port as Primary only. Also, check each IDE device for the proper master/subordinate/stand-alone setting. Try removing all IDE devices except for hard disks. If the message appears during an installation of Windows, make sure that the computer and all installed peripherals are listed in the Microsoft Windows Marketplace Tested Products List.

How long do LCD Projectors operate?
LCD projectors themselves can last for years and years and years if properly cared for. The bulb, however does have a finite lifespan and is very expensive to replace...
LCD projector bulbs are usually rated for their average expected lifespan. This if often in the range of around 2000 hours of use. Most bulbs will continue to work well past this, although there may be a reduction in brightness.
What is small computer serial interface used for?
I am assuming you mean what is SCSI used for? In this case, SCSI does NOT mean "small computer serial interface," instead, it means "Small Computer SYSTEM Interface." SCSI is used as a fast interface between a host adapter and the CPU that can daisy chain as many as 7 or 15 devices on a single bus.
