A block of memory built into the microprocessor which
is much faster to access than your system RAM and used
in specially structured ways to make your overall data
handling time faster.
CardBus
A faster, 32-bit version of the PC Card interface
which offers performance similar to the 32-bit
PCI architecture.
CMOS RAM
Complementary metal oxide semiconductor random
access memory. This is a technology for manufacturing
random access memory which requires very low levels of
power to operate.
COMM Port
Abbreviation for communication port. This is your
serial interface connection.
Command
An instruction which you give your operating
system. Example: run a particular application or
format a floppy disk.
Configuration

of electronic particles striking a luminescent screen. It
produces a visual image by varying the position and
intensity of the beam.
Data
The information a system stores and processes.
DC
Direct current. A voltage or current that does not
fluctuate periodically with time.
DDR
Double Data Rate
Fast version of SDRAM that provides twice the band-
width of standard SDRAMs.
Default Value
A pre-programmed value to be used if you fail to
set your own.
DIMM
