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
