802.2
This IEEE standard specifies Logical Link Control
(LLC), which defines services for the transmission of
data between two stations at the data-link layer of the
OSI model.
802.3
Often called Ethernet, this IEEE standard governs the
Carrier Sense Multiple Access/Collision Detection
(CSMA/CD) networks. Typical cabling standards are
10BASE-T, 10BASE2, and 10BASE5.
Access Method
The set of rules by which the network determines what
node has access to the network. The two most popular
access methods are Collision Sense Multiple
Access/Collision Detection (Ethernet) and token passing
(Token Ring and ARCNET).
Anomaly
An impedance discontinuity causing an undesired signal
reflection on a transmission cable.
AppleTalk
The set of protocols that define Apple Computer’s
networking specification.
ARP (Address Resolution Protocol)
A member of the TCP/IP protocol suite, ARP is the
method by which a station’s MAC address is determined
given a station’s IP (Internet Protocol) address.
Attenuation
A reduction in the strength of a signal; the opposite of
gain.
Bandwidth
Bandwidth is the rate at which data can be transmitted
over a channel, measured in bits per second. For
example, Ethernet has a 10 Mbps bandwidth and FDDI
has a 100 Mbps bandwidth. Actual throughput is almost
always less than the theoretical maximum.
BPS
Bits per second. A measure of speed or raw data rate.
Often combined with metric prefixes as in kbps (for
thousands of bits per second) or Mbps (for millions of
bits per second).
Bridge
A device that links two or more networks that use the
same OSI Data Link protocol. A bridge evaluates source
and destination addresses to pass only frames that have a
destination on the connecting network.
