C
cache memory: High speed memory which stores data that increases
processor speed and data transfer rate. When the CPU reads data
from main memory, it stores a copy of this data in cache memory.
The next time the CPU needs that same data, it looks for it in the
cache memory rather than the main memory, which saves time.
The computer has two cache levels. Level one is incorporated into
the processor and level two resides in external memory.
capacity: The amount of data that can be stored on a magnetic storage
device such as a diskette (floppy disk) or hard disk. It is usually
described in terms of kilobytes (KB), where one KB = 1024 bytes
and megabytes (MB), where one MB = 1024 KB.
Card Station II: A device that enables onepoint connection to a number
of peripheral devices and provides additional ports and slots.
card: Synonym for board. See board.
CardBus: An industry standard bus for 32bit PC Cards.
CDR: A Compact DiscRecordable disc can be written once and read
many times. See also CDROM.
CDROM: A Compact DiscRead Only Memory is a high capacity disc
that can be read from but not written to. The CDROM drive uses a
laser, rather than magnetic heads, to read data from the disc.
CDRW: A Compact DiscRead/Write disc can be rewritten many times.
Centronics: A printer manufacturer whose method of data transmission
between a parallel printer and a computer has become an industry
standard.
CGA: Colour/graphics adaptor. A video display protocol defined by the
IBM Colour/Graphics Monitor Adaptor and its associated circuitry.
This protocol supports twocolour 640x200 and fourcolour
320x200 graphics, and 16colour 640x200 and 320x200 text
modes.
character: Any letter, number, punctuation mark, or symbol used by the
computer. Also synonymous with byte.
chassis: The frame containing the computer.
chip: A small semiconductor containing computer logic and circuitry for
processing, memory, input/output functions and controlling other
chips.
CMOS: Complementary MetalOxide Semiconductor. An electronic
circuit fabricated on a silicon wafer that requires very little power.
Integrated circuits implemented in CMOS technology can be
tightly packaged and are highly reliable.
cold start: Starting a computer that is currently off (turning on the power).
COM1, COM2, COM3 and COM4: The names assigned to the serial and
communication ports.
