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

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

flowing at 1 volt.
WH

R

— 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.

XGA — extended graphics array — A video standard for video cards and 

controllers that supports resolutions up to 1024 x 768.

Z

— 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.

— A high-capacity floppy drive developed by Iomega Corporation that 

uses 3.5-inch removable disks called Zip disks. Zip disks are slightly larger than 

regular floppy disks, about twice as thick, and hold up to 100 MB of data.
