*VAC*		Volts Alternating Current.
vaporware		Software that has been announced but doesn't exist yet.
VESA		(veesa) Video Electronics Standards Association. The source of a Super VGA standard used on many video boards.
VGA		Video Graphics Array. 640 480 16 resolution. Can have more colors if there is enough video RAM.
video adapter		See video controller.
video card		See video controller.
video controller		An expansion card whose function is to convert signals in the computer into signals the monitor can display.
video RAM		Memory on a video card that enables or speeds up drawing to the screen or increases resolution.
virtual memory		Memory addresses and data that appear to the CPU to be in RAM but actually are on a hard disk. Special software manages this memory and gives the CPU access to it.
virus		Software that copies itself onto hard drives and floppies without user intervention, usually when a floppy is placed into the drive of a computer. Viruses usually carry a payload (qv), triggered by some preset condition. Viruses are frequently written with antisocial intent.
virus checker		Software whose purpose is to detect and remove viruses from a system.
VIVO		When mentioned with the Ensoniq Soundscape wavetable sound card, VIVO does not refer to anything.
VLSI		Very Large Scale Integration. IC's that have 5,000 to 50,000 components. Single components are microscopic.
.VOC		The usual extension for a Sound Blaster sound file filename.
voice mail		A technical term used to describe a phone message left on an answering machine or audix.
volatile		IC's that loose their state when the power is shut off. Compare nonvolatile.
volume label		An 11-character electronic label that can be created for hard or floppy disks. Labels are created with the LABEL command in DOS, and read with the VOL command.
VRAM		(vee-ram) Video Random Access Memory. Utilizes a dual port design, allowing the accelerator chip and RAMDAC to access the frame buffer simultaneously. In other words, it's cooler than DRAM, but not as cool as WRAM.
