CSMA/CD (Carrier Sense, Multiple Access with Collision Detection)

In CSMA/CD, each node or station has equal access to the network. Before transmitting, each station waits until the network is not busy. Since each node has equal access to the network, a collision (two stations transmitting at the same time) can occur. If a collision occurs, the affected nodes will wait a random time to retransmit. Ethernet uses the CSMA/CD access method.

dBm

Decibels below 1 mW (1 milliwatt). The logarithmic measure of the ratio of the output power of a signal to an input signal of 1 mW.

DECnet

Digital Equipment Corporation’s set of communication protocols for networking computers.

Destination Address

The address of the station receiving a frame.

EIA568

Electronic Industries Association Commercial Building Telecommunications Wiring Standard. Specifies maximum cable lengths, installation practices, and performance specifications for generic building wiring.

Encapsulation

Encapsulation is the method of placing one protocol into another protocol’s format. For example, in a Novell Ethernet environment there are four different methods to encapsulate IPX in Ethernet/802.3 frames: 802.3 raw, 802.2, Ethernet II, and SNAP.

Ethernet

Ethernet is a 10 Mbps topology that runs over thick coax, thin coax, twisted-pair, and fiber-optic cabling systems.

Fast Ethernet

Industry standard terminology for 100Base-T. Industry groups do not agree on using the term to refer to 100VG- AnyLAN; some call 100VG-AnyLAN a Fast Ethernet technology while others do not.

FCS (Frame Check Sequence)

A field transmitted in LAN frames that encodes error checking information.

Frame

A frame is the transmission unit on a network. In Token Ring, a frame is the token joined with node data.
