Cat 5
Category 5 unshielded twisted pair (UTP) cabling. An Ethernet network operating at 10 Mbits/second
(10BASE-T) will often tolerate low quality cables, but at 100 Mbits/second (10BASE-Tx) the cable must be
rated as Category 5, or Cat 5 or Cat V, by the Electronic Industry Association (EIA).
This rating will be printed on the cable jacket. Cat 5 cable contains eight conductors, arranged in four
twisted pairs, and terminated with an RJ45 type connector. In addition, there are restrictions on maximum
cable length for both 10 and 100 Mbits/second networks.
Capacity planning
Determining whether current solutions can satisfy future demands. Capacity planning includes evaluating
potential workload and infrastructure changes.
Checksum
A simple error-detection scheme in which each transmitted message is identified with a numerical value
based on the number of set bits in the message. The receiving station then applies a formula to the message
and checks to make sure the accompanying numerical value is the same. If not, the receiver can assume that
the message has been corrupted.
Class of Service
A term to describe treating different types of traffic with different levels of service priority. Higher priority
traffic gets faster treatment during times of switch congestion
CLI
See "Command Line Interface" on page 4.
Collision
A term used to describe two colliding packets in an Ethernet network. Collisions are a part of normal
Ethernet operation, but a sudden prolonged increase in the number of collisions can indicate a problem with
a device, particularly if it is not accompanied by a general increase in traffic.
Command Line Interface
CLI is a line-item interface for configuring systems.
D
DHCP
See "Dynamic Host Configuration Protocol" on page 5.
