APPENDIX
USB (Universal Serial Bus)
USB is a 4-pin serial peripheral bus that is capable of cascading low/
medium speed peripherals (less than 10Mbit/s) such as keyboard, mouse,
joystick, scanner, printer and modem.
VCM (Virtual Channel Memory)
NEC's Virtual Channel Memory (VCM) is a new DRAM core
architecture that dramatically improves the memory system's ability to
service multimedia requirements. VCM increases memory bus efficiency
and performance of any DRAM technology by providing a set of fast
static registers between the memory core and I/O pins. Using VCM
technology results in reduced data access latency and reduced power
consumption.
VRM (Voltage regulator Module)
This is a small module installed on a mainboard to regulate the voltage
fed to the processor on board. Voltage regulator can be built on board in
various way. VRM is a socketed type of regulator module which is easier
to change when needed.
Zero Wait State
When memory is operating at its fastest speed in its course of fetching
and yielding data, it allows no "no-op" cycle and is called in a zero wait
state. On the other hand, a memory is in a wait state , after it gets a
command to fetch data, it waits for one , two or more cycles to assure
that the expected data is in the buffer.
ZIP file
Zip file is a compressed file with a reduced file size.
Zoom
To zoom is to make a window or screen larger or smaller in a Graphical
User Interface of a computer system. Usually, to "zoom in" means to
enlarge, and to "zoom out" means to reduce size.
