Bus or Channel
A common physical path composed of wires or other media, across which signals are sent from
one part of a computer to another. A channel is a means of transferring data between modules
and adapters, or between an adapter and SCSI devices. A channel topology network consists of
a single cable trunk that connects one workstation to the next in a daisy-chain configuration.
All nodes share the same medium, and only one node can broadcast messages at a time.
CA
Short for
Certificate Authority
. A trusted third-party in a network that issues and manages
security credentials.
Cat 5 Cable
Short for
Category 5
, it is network cabling that consists of four twisted pairs of copper wire
terminated by 8P8C modular connectors. CAT 5 cabling supports frequencies up to 100 MHz
and speeds up to 100 Mbps. It can be used for ATM, token ring, 100BASE-T, and 10BASE-T
networking.
Cat 5 is based on the EIA/TIA 568 Commercial Building Telecommunications Wiring
Standard developed by the Electronics Industries Association as requested by the Computer
Communications Industry Association in 1985.
Cat 6 Cable
Short for
Category 6
, it is network cabling that consists of four twisted pairs of copper wire
terminated by 8P8C modular connectors made to higher standards that help reduce noise
caused by crosstalk and system noise. The ANSI/TIA-568-B.2-1 specification states the cable
may be made with 22 to 24 AWG gauge wire, so long as the cable meets the specified testing
standards.
It is designed for Gigabit Ethernet that is backward compatible with the Category 5/5e and
Category 3 cable standards. Cat 6 features more stringent specifications for crosstalk and
system noise. The cable standard provides performance of up to 250 MHz and is suitable for
10BASE-T, 100BASE-TX, and 1000BASE-T (Gigabit Ethernet).
Channel
A communications path between two computers or devices.
Checksum
The result of adding a group of data items that are used for checking the group. The data items
can be either numerals or other character strings treated as numerals during the checksum
calculation. The checksum value verifies that communication between two devices is
successful.
CIFS
Short for
Common Internet Filesystem
.
Also known as
. The default Windows protocol for
communication between computers. A specification for an Internet file access protocol that
complements HTTP and FTP.
daemon
A process that runs in the background.
default gateway
The router used when there is otherwise no known route to a given subnet.
