Why is computer programming necessary?
For a computer to do useful things, it has to be told what to do. That is where computer programming comes into play. However, computers require complex sequences of electrical signals which are difficult to learn and would require constant use of reference books. To simplify the process, you would learn a more human-friendly language, and a compiler converts what you type into the opcodes that represent these complex electrical signals. Then you would run a linker or similar build tool to add the required finishing touches and resolve all dependencies (references to other code and functions).
How do you get a usb Flash drive read as a CD?
A flash drive is not a cd and therefore cannot be read like one.
It is a program that restarts your computer. It sounds like you may have a corrupted program on your computer that is causing the problem. This happens for many reasons . It happens most often during reloading of programs and may have happened at the factory. No way of knowing for sure.
I would suggest doing a systems restore. This should be already on your computer.
If you do not know how, contact your ISP or computer manufacturer and hey will instruct you on what to do. Your computer should me under warrantee and while it is this service should be free.
ANSWER:
Let's ask a few questions before we can isolate the issue. First, how long have you owned your computer? (Is it new? Have you had it for a few years? Have you been doing your updates as they come in?) Second, did you add new hardware? (if you did, was it a communications device? IE: network card, wireless card, modem.) And further, did you use a PCI slot that wasn't the last in the chain? (The very bottom of the board, or close to the video card?) And lastly, did you install a new memory stick?
Now, let's address each of these things.
- If the computer is new and you are having this continual re-boot issue, you should contact the manufacturer for support. If you had it for a while, go to the next step.
The most current updates that can, and have regularly, caused the issue you describe are the service updates, or "service packs" for Windows XP Pro or Home. (Mostly SP2) The registry and MBR (Master Boot Record) are not re activated correctly due to a bad downloaded .EXE) In this case, there is only one thing to do. You must remove or uninstall the service pack. Both, SP2 and SP3 have an uninstall program, and it can be performed through the "Add/Remove" tab in the "Control Panel" Since the computer won't boot beyond the initial bios start-up, then you will need to keep your finger at the ready to hit F8 so you can enter "safe mode" (pressing the F8 key on your keyboard repeatedly during the bios startup.) If you are successful, then navigate your way to the Control Panel and then to the Add/Remove tab. simply remove the service pack, and reboot the computer. The original condition should be achieved at this point, and you can try to let the Update site try again, or, you could just go to the Microsoft website and download the service pack manually. Because of the length of the instructions, go to: http://support.microsoft.com/kb/875350 Here you will find the instructions to help you remove the SP in several different ways. (I recommend you go straight to the last one since you can't boot into windows.)
- Almost all mainboards now, have sound and network cards "built in" and are not required to have add on cards. Most of the new system architectures of today have a specific slot in which to install a communications device, should the need for additional or replacement cards to be installed. They are "Electronically Keyed" as are the new cards, so that the communications device can only work in the one "slot". (This has to do with the addition of the PCI-E bus in the newer systems.) In most systems, the location will be at the last slot on the board. (The furthest away from the CPU.) Some manufacturers have been gracious to color the slot "orange". Soon, it will become a standard, but until that day, currently, most manufactures enter this vital information in their manuals as a side note. Not fair to the most of us, but hey,,,it's their thing….for now! The result of installing the communications card in the wrong slot will yield the problem you have described. In some cases, the computer won't even start. (The board, power supply or both will detect a voltage variant and prevent the startup to prevent damage to the board and interface.)
- And lastly, with the advent of DDR2 and the PCI-E boards, there are some issues with memory and the types being used. Some boards have color-coded memory slots. IE: if you have three or more memory slots, (4 is the most on most boards) 2 will be the same color, and the 1 or 2 if there are 4 will be a different color. This would indicate that a.) if you are running two "like" sticks of memory, they should be installed in the same colored slots, leaving the 1 or 2 slots empty. (Even if the board has a "blue-black-blue-black" you would only use the "blue-(empty)-blue-(empty) configuration.) b.) if you are using size different sticks, then the slots "color code" would be used. IE: if you have two sticks of 512mb and one stick of 256mb then the two 512's would occupy the "blue" slots, and the 256 would occupy the "black" slot(s) This also applies to the "FSB speed" (Front Side Bus) of the memory. Ideally, two sticks that are of a different speed, (yet the board supports both speeds) then you would segregate the speeds in the corresponding coded slots.
In summery, there are several things that could cause the issues you have described. Check each one, and see if any of the suggestions mentioned here, could be a resolution. At the last ends, take your computer to a qualified technician, and have them fix it for you.
How do you load the printer with paper?
It depends what printer you have. All printers are different. A Deskjet 970 cxi just has you insert paper at the tray underneath the top tray that can pivot up and down (where the paper comes out).
How does data on a hard disk determine the speed of a computer?
It doesn't actually change the speed of the computer, but it can change how fast the computer 'feels' because while the PC is reading/writing from the hard drive other things are slower. The longer the data takes to read or write, the slower the computer feels. Because of this faster hard drives are often part of performance class machines.

CMOS is a small component cluster on a computer motherboard which hold a very small amount of simple information. It has a large button battery which supplies the needed power to preform one of its main functions: Keep date and time. It also holds vital system settings.
Basicly, It is a small memory componant, but users can not store data on it aside from system boot settings.
How many cores can a computer have?
Computer processor cores come as single core (one processor), Dual core (two processors), Quad core (four processors) and Six Core. Although apple now offers a computer which can have 8 or 12 cores
How do you reset a PC that will not turn on?
That's vague. I'll try to answer several possibilities. if it would not turn on, and you removed the battery, and you pressed reset, and then reinserted the battery, and attached the battery charger/power adapter, and the AC power light comes on, and then you pressed power, and it still won't come on, and you also tried to power on without the battery installed, running on just the charger/ adapter, *then, your laptop has a serious problem.
Can you use a 65w ac adapter for a Thinkpad T500 instead of a 90w?
According to Lenovo, you can use a 65W AC adapter for T500 models equipped with integrated graphics chips (Intel graphics). If you have the discreet graphics chip (ATI graphics), you should use the 90W AC adapter.
How do you determine if your system is set to boot from a CD or floppy disk?
on startup hit f1/del/f10 to open bios, select advance setup, select boot priority/order/device, select what u want, f10, Y, ENTER. *some pc require different method.
Should you delete system32 to speed up your computer?
NO, system 32 is your computer's operating system. if you delete your system 32, you might as well buy another computer.
How do you refill Epson Ink Cartridges?
you need a chip resetter to rifill these cartriges
The ink cartridges used in Epson's Stylus line of printers are very similar to the ones used in its other printers. A handful of cartridges--like the S020034, S020047 or S020049--may require a slightly different refilling technique, but they all basically entail opening a fill hole in the top to run down into the ink chamber within. Once the chamber is accessible, you can use a basic refill kit with a syringe bottle to refill the chamber, as with most printer-ink cartridges.
1.Hold the cartridge upside down so the outlet holes to the printer paper are on top. Cover each hole with a piece of tape, then turn the cartridge right-side up.
2.Make a hole in the top of the cartridge above each ink chamber. For most cartridges, simply poke a hole through the label with a toothpick. With cartridges like the Epson Stylus 34 (the casing of which is black), pull back the label to reveal the filling holes and puncture the seal of each home. For the 47 or 49 color cartridge, drill a 1/8-inch hole in the shell between the label and front edge.
3.Determine which color of ink is in which chamber (if you're refilling a color cartridge). The toothpick used to puncture the hole should draw out some ink to show you. If you have a cartridge in which you punctured the label directly, the order of the color chambers is usually cyan, magenta and yellow. If you created the hole in another way (like with the 34, 47 or 49 cartridges), the order is usually magenta, cyan and yellow.
4.Fill the syringe bottle with 5ml of ink. Insert the needle in the filling hole and inject the ink. There may be a sponge inside the chamber, so make sure the needle goes all the way through to the bottom. The 34 cartridge takes up to 12ml of ink.
5.Tape over the fill holes you created. If you drilled the holes, plastic plugs (like the ones included in a refill kit) can work as well. Leave the tape on the outlet holes as you replace the cartridge in the Epson Stylus printer.
6.Run a cleaning or priming cycle on the printer with the cartridge installed. One to three cycles should be enough. You may also need to let the cartridge stand in the printer overnight, or for up to 24 hours.

Check your mouse cord to see if it's plugged in all the way. If it's of PS/2 type, the little needles may need to be straightened if you plugged it in too excitedly a few times. Some needle-nose pliers and some TLC should do the trick. Also, if you plug in a PS/2 mouse while the computer's on, you'll need to restart in order for it to work. If it's USB, make sure there's no junk in either the plug or the connector and try again. There may be a problem with that USB port. Try another one. Another thing to do is clean the mouse. If it's an optical (laser) mouse, make sure there's no hair on the lens. Use a dry, clean, soft, lint-free cloth, just in case. If it's a mouse with the traditional ball, take the ball out and clean the little rollers with an (unused) ear cleaner and some cleaning solution. Still have problems? Make sure the cord isn't frayed or broken anywhere. If it is, or if nothing else works, throw it out and buy a new mouse! If you just can't live without your specific beloved mouse and don't want to buy another one, see if you can find a loophole in the manufacturer's warranty. Otherwise, you're out of luck! P.S. If you ever upgrade to another mouse for no real reason, don't throw the old, working mouse away. Instead, keep a supply in your basement or somewhere for when calamities such as this one strike.
How do you find and delete a virus in the hard drive?
Go to search on the start option and search for system restore. If you have this program click on the results. Restore your computer to a day when you did not have the viruses. Your information will not be deleted, only harmfull programs will. This might not work but it is worth giving it a try.
Why does software need updating from time to time?
One good reason software needs to be updated is get rid of problems the program maybe having that is due to improper programming. In other words new version get rid of the bugs and other problems. Sometime it is updated to make the program easier to use and add features that the original didn't come with.
How do you Maintain a computer Keyboard?
Never press the keys in the keyboard hardly. As much as possible, buy a keyboard with smooth keys so that typing is really smooth and easy. Do not keep buttons pressed continuously. Do not hit the keys hardly, especially the enter key. If you are frustrated or restless, find other ways of releasing it, rather than hitting the keys on the keyboard. Do not bang or move your fingers across the keys carelessly, like in a piano.
Keep the keyboard in a place that is dry and free of dust. Dust gets settled easily especially in between the keys and is difficult to remove. Buy a transparent light cover for the keyboard, so that dust cannot enter easily and you can keep the cover on while typing. However, if the climate gets humid and moist, check the cover for signs of moisture. If you see drops of water, remove the cover so that water does not enter the keyboard.
How do you repair BSOD - Blue Screen of Death - on your computer?
Can depend on what caused it. It means the machine can't decide what to do next so it goes belly up (BSOD).
If you installed some new hardware the problem might be that....called a driver problem quite often. Need to uninstall it and read instructions or call manufacture.
Sometimes a simple restart will clear things up.
If you didn't installed anything, hardware of software and the machine is a few years old some component might have gone bad and the computer doesn't know what to do next. The next step is to open it up and start disconnecting things and restarting to find out what's causing the problem. This of course requires some 'puter knowledge, best left to the pros.
Each laptop allow to remove its keyboard, go through the manual how to, remove the keyboard. Usually each key can be removed too, make sure that you know how to... Remove each key and clean with clean water, dry it before installation. Clean the keyboard body with slightly wet tissue, dry before installation.
What is the purpose of a firewall on your computer?
Its primary function is to prevent accesses from untrusted (or undesired) external systems to internal systems and services, and to prevent internal users and systems to access external untrusted or undesired systems and services.
More generally, its purpose is to implement security and performance policies.
As an example, you can prevent external systems to access internal servers, as well as to prevent users to use P2P software or access social networks, for performance and security reasons.
Why should you back up your files?
You should always back up your computer files just in case your computer decides to go kaput. When you back up your files on another drive, you can always have access to them.
