capacity: The amount of data that can be stored on a magnetic storage
device such as a 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.
CardBus: An industry standard bus for 32-bit PC cards.
CD-ROM: A Compact Disc-Read Only Memory is a high capacity disc that
can be read from but not written to. The CD-ROM drive uses a laser,
rather than magnetic heads, to read data from the disc.
CD-R: A Compact Disc-Recordable disc can be written once and read
many times. See also CD-ROM.
CD-RW: A Compact Disc-Read/Write disc can be rewritten many times.
See also CD-ROM.

Integrated circuits implemented in CMOS technology can be tightly
packaged and are highly reliable.
compatibility: 1) The ability of one computer to accept and process data in

components: Elements or parts (of a system) which make up the whole
