A: Don't drop them or place them on anything other than in the CD case or drive. The data is read by way of light transmission. If they are smudged, they may not be able to be read properly. Scratches can also ruin a CD. Leaving a CD in the sunlight will warp it.
Q: How do I clean a CD?
A: Don't spray chemicals directly on the disk because it will leave a film. Buy reusable fiber wipes. Wipe in a circle because the tracks on the CD are circular.
Q: How quickly data can move from a network to your computer. It is measured in kilobits or megabits per second. The bigger the bandwidth, the more it costs.
A: You may have the wrong URL address, or the server that you are connecting to may be down.
A: You have a mouse on the run. The mouse needs to be cleaned. The bottom of the mouse pops off to enable easy cleaning of the rubber ball ( also trackballs) and the inner rollers that the mouse has contact with. Clean the mice with cotton swabs and a touch of alcohol. You can spray canned air through accessible areas.
Q: How do I clean my monitor?
A: Use a soft, lint-free cloth. Some companies sell antistatic sprays, screen wipes etc. Don't wash with soap and water. Be sure and turn off your computer before cleaning. You could easily get electrocuted if there are any voltage leaks. Don't put your fingers on the monitor because they leave oils and acids on the screen from your skin.
A: It is the smallest unit of computer data, and acronym for binary digit, the bit has a value of either 0 or 1. American John Tukey invented the term in 1946, and it is still the standard for data measurement.
Q: My child had a magnet on top of one of my diskettes, now we can not read it. What happened?
A: Magnets are sworn enemies of computers, they can easily erase data on floppies and also the hard drive. Magnets have also been know to mess up computer monitors quite nicely.
A: It is the measurement of bandwidth (see bandwidth). Measured as the number of electrical oscillations that occur in a second, each oscillation holds one bit of data. The bit rate is usually the same as the baud rate. Older modems measured in baud rates, newer modems measure in kilobits per second.
A: The spine of any computer network is known as a backbone, it ties different computers together. The collection of fiber optic cables that connect computers around the world is the backbone of the Net.
A: It is when a computer freezes up in the middle of a program. The bomb will wipe out any data that hasn't been saved. This is not the same as a system crash, which shuts down the whole computer, but the bomb only affects a single program. If the bomb is really bad, it can affect the whole system and cause it to crash.
Q: My machine won't boot and I get a message saying that it has lost its Setup or CMOS setting. What is wrong with it?
A: Changes are the battery that powers the CMOS is dead. These batteries last from two to five years. Most new systems have their batteries as part of the motherboard and do not need replacing.
Q: What do I do if I get and error message that my printer or mouse is not responding?
A: The problem may be in your hardware. Check cables for tightness. (When the computer is off of course). Use the thumbscrew tightners that are on most serial and parallel cables. Use twist ties to hold cables together.(Be sure and ground yourself by touching an unpainted metal surface first.) Make sure that the cables are not under stress. Check for cable kinks.
A: The basic input/output system (BIOS) has a responsibility for staring up the computer and getting it ready to run programs. When a PC is turned on and you see numbers counting up on the screen your're watching as the BIOS checks the memory and prepares to start up the operating system. The BIOS is the one thing your computer needs to stay alive.
A: It is the making of new software that can run on old computers. Instead of writing off old computers, most software companies decided to write software that could be used on older machines.
A: It may be a number of things. the drive might be dirty and you need to run a cleaning diskette. If the error always appears in a particular part of a program then part of the program may be corrupt. Try this: remove the diskette, reinsert it, and trying reading it again. Repeat the process two or three times. If this still doesn't work, then the drive head may be out of alignment.
