Bandwidth
The information capacity, measured in bits per second, that a channel could transmit. Bandwidth examples
include 10 Mbps for Ethernet, 100 Mbps for Fast Ethernet, and 1000 Mbps (I Gbps) for Gigabit Ethernet.
Baud
The signaling rate of a line, that is, the number of transitions (voltage or frequency changes) made per
second. Also known as line speed.
Broadcast
A packet sent to all devices on a network.
C
CA
A Certificate Authority is a trusted third-party organization or company that issues digital certificates used
to create digital signatures and public-private key pairs.
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.
Certificate Authority
A Certificate Authority is a trusted third-party organization or company that issues digital certificates used
to create digital signatures and public-private key pairs.
The role of the CA in this process is to guarantee that the individual granted the unique certificate is, in fact,
who he or she claims to be. Usually, this means that the CA has an arrangement with a financial institution,
such as a credit card company, which provides it with information to confirm an individual's claimed
identity. CAs are a critical component in data security and electronic commerce because they guarantee that
the two parties exchanging information are really who they claim to be.

traffic gets faster treatment during times of switch congestion
