byte
Abbreviation for binary term, a unit of storage capable of
holding a single character. On almost all modern computers, a
byte is equal to eight bits. Large amounts of memory are
indicated in terms of kilobytes (1024 bytes), megabytes (1 048
576 bytes), and gigabytes (1 073 741 824 bytes).
cache
A read cache attempts to anticipate and store required data in
memory so that it can be retrieved quickly (electronically, rather
than mechanically). A write cache electronically holds the data
you want to write to disk and slowly writes it to the disk
(mechanically).
call source
The node from which an incoming call originates. A call can
initially be presented to the local node or to another node on the
network.
Calling Line Identification
The telephone number of the person who called.
CDN
See controlled directory number.
CD-ROM
A type of optical disk capable of storing large amounts of data
(up to 1Gbyte), although the most common size is 630Mbytes.
A single CD-ROM has the storage capacity of 700 floppy disks
and is particularly well-suited to information that requires large
storage capacity.
