Buffer - A storage area used for handling data in transit. Buffers are often

 

used to compensate for differences in processing speed between network

 

devices.

 

Byte - The fundamental unit that a computer uses in its operation. It is a

 

group of adjacent binary digits, usually 8, often used to represent a single

 

character.

 

Cable Modem - A device that connects a computer to the cable television

 

network, which in turn connects to the Internet. Once connected, cable

 

modem users have a continuous connection to the Internet. Cable modems

 

feature asymmetric transfer rates: around 36 Mbps downstream (from the

 

Internet to the computer), and from 200 Kbps to 2 Mbps upstream (from

 

the computer to the Internet).

 

Caching – 1. Speeds information processing by storing information from

 

a transaction to use for later transactions. 2. Storing or buffering data

 

in a temporary location, so that an application program can retrieve the

 

information quickly.

Carrier Sense Multiple Access/Collision Detection (CSMA/CD) -A channel access mechanism wherein devices wishing to transmit first check the channel for a carrier. If no carrier is sensed for some period of time, devices can transmit. If two devices transmit simultaneously, a collision occurs and is detected by all colliding devices, which subsequently delays their retransmissions for some random length of time. CSMA/CD access is used by Ethernet /IEEE 802.3 and HomePlug.

CAT 3 - ANSI/EIA (American National Standards Institute/Electronic Industries Association) Standard 568 is one of several standards that specify "categories" (the singular is commonly referred to as "CAT") of twisted pair cabling systems (wires, junctions, and connectors) in terms of the data rates that they can sustain. CAT 3 cable has a maximum throughput of 16 Mbps and is usually utilized for 10BaseT networks.

CAT 5 - ANSI/EIA (American National Standards Institute/Electronic Industries Association) Standard 568 is one of several standards that specify "categories" (the singular is commonly referred to as "CAT") of twisted pair cabling systems (wires, junctions, and connectors) in terms of the data rates that they can sustain. CAT 5 cable has a maximum throughput of 100
