Glossary

Although they are faster than DRAM, they hold less data and are more ex- pensive.

Synchronous - Protocols that require the clocks of communicating ma- chines or devices to be coordinated.

Synchronous Cache - A type of cache that uses a clock signal to latch the inputs and the data output. This struc- ture spreads the cache access across two or three cycles while maintaining a bandwidth of one access per cycle. Improves performance by 5-10%.

Terabyte - A measurement for very large storage capacity. One Terabyte is equiva- lent one-thousand gigabytes, one-million megabytes, or 1,099,511,627,766 bytes.

VESA - An acronym for Video Elec- tronics and Standards Association.

VESA Local Bus (VL-Bus) - A high performance bus designed by VESA.

A32-bit version of the ISA bus which operates at the speed of the computer’s CPU. See PCI, EISA and ISA.

VID - Voltage Identification. A hard- ware mechanism used by the CPU to tell its power regulator what voltage to set.

VRM - Voltage Regulator Module. Supplies CPU specific voltages for the Secondary CPU.

Warm Boot - Restarting the system by simultaneously pressing the <Ctrl>, <Alt> and <Delete> keys.

Wide SCSI - A SCSI-2 enhancement that allows data to be transferred 16 or 32 bits at a time on the SCSI bus instead of 8 bits at a time.

Write-Back Cache - Upon a cache hit, the cache is updated and the main memory is not affected. Upon a cache miss, only the main memory is up- dated.

Write-Through Cache - Upon a cache hit, the cache and the main memory are updated. Upon a cache miss, only the main memory is up- dated.
