virus — A program that is designed to inconvenience you or to destroy data stored on your computer. A virus program

moves from one computer to another through an infected disk, software downloaded from the Internet, or e-mail

attachments. When an infected program starts, its embedded virus also starts.

A common type of virus is a boot virus, which is stored in the boot sectors of a floppy disk. If the floppy disk is left in the

drive when the computer is shut down and then turned on, the computer is infected when it reads the boot sectors of the

floppy disk expecting to find the operating system. If the computer is infected, the boot virus may replicate itself onto all the

floppy disks that are read or written in that computer until the virus is eradicated.

V — volt — The measurement of electric potential or electromotive force. One V appears across a resistance of 1 ohm when a

current of 1 ampere flows through that resistance.

W — watt — The measurement of electrical power. One W is 1 ampere of current flowing at 1 volt.

WHr — watt-hour — A unit of measure commonly used to indicate the approximate capacity of a battery. For example, a 66-

WHr battery can supply 66 W of power for 1 hour or 33 W for 2 hours.

768.

ZIF — zero insertion force — A type of socket or connector that allows a computer chip to be installed or removed with no

stress applied to either the chip or its socket.

Zip — A popular data compression format. Files that have been compressed with the Zip format are called Zip files and

usually have a filename extension of .zip. A special kind of zipped file is a self-extracting file, which has a filename extension

of .exe. You can unzip a self-extracting file by double-clicking it.

Zip drive — A high-capacity floppy drive developed by Iomega Corporation that uses 3.5-inch removable disks called Zip
