Coaxial Cable
Coaxial cable is also called coax and used to transmit radio frequency (RF)
signals. It is the kind of copper cable with a central conductor that’s
surrounded by a shield sharing its same axis. It is often used by cable TV
companies, telephone companies, and business and corporation Ethernet
and other types of local area network.
CODEC
CODEC means the technology used to compress and decompress data
stream or signal. It converts analogue input into digital, and then converts it
back to analogue. CODECS can be either software applications or hardware
components, or both. CODEC does coding and decoding, containing no
compression.
CGI
CGI is the abbreviation of Common Gateway Interface. It is a standard
protocol for interfacing external applications with information servers, such
