Cache
An area of high-speed
RAM
set aside to store frequently accessed data. When
data is accessed, a copy is stored in cache memory. The next time the
microprocessor
looks for information, it first checks the cache. If the data is
there, the microprocessor retrieves it from the much-faster cache memory.
Drive caching and RAM caching significantly improve the overall speed of
the computer. See also
L
and
L2 Cache
.
CD
Compact disc
. An optical form of storage media, typically used for audio and
application programs.
CD-R
CD recordable
. A recordable version of a
CD
. Data can be recorded only once
onto a CD-R. Once recorded, the data cannot be erased or written over.
CD-RW
CD rewritable
. A rewritable version of a
CD
. Data can be written to a CD-
RW, then erased and written over (rewritten).
Chip
See
IC
.
CIM
Common Information Model
. CIM allows remote management application
programs to access system management information on a client computer
running any Microsoft Windows
®
OS
that includes the
WBEM
core
components.
Clock Speed
The speed, given in
MHz
, that indicates how fast computer components
operate that are connected to the system
bus
. The speed is generated by a
quartz crystal on the system board that acts as a kind of metronome.
Components that are synchronized with the clock speed can run faster or
slower, but their speed is determined by multiplying or dividing a factor by
the clock speed.
cm
Centimeter(s)
. A measurement of length equal to 0.39 inch.
CMOS
Complementary metal-oxide semiconductor
. Memory
chips
that are often used
for
NVRAM
storage.
