Glossary

Chassis View

Avaya Inc.’s Network Management System’s graphic depiction of a network device.

Client

A computer system or process that requests a service from another computer system or process (a "server"). Typically, a client is an application that runs on a personal computer or workstation and relies on a server to perform some operations.

Collision

In Ethernet, a collision occurs as the result of two nodes transmitting simultaneously. The frames from each device impact and are damaged from the impact.

CRC

Cyclic Redundancy Check. A data transmission error-checking technique in which the frame recipient calculates a remainder by dividing frame contents by a prime binary divisor and compares the calculated remainder to a value stored in the frame by the sending node.

CSMA/CD

Carrier Sense Multiple Access with Collision Detection. A multi-user network allocation procedure in which every station can receive the transmissions of all others. Each station waits for the network to be idle before transmitting and each station can detect collisions by other stations.

Data Link Layer

Layer 2 of the OSI reference model. The Data Link Layer is responsible for physical addressing, network topology, line discipline, error notification, ordered delivery of frames, and flow control.

DHCP

Dynamic Host Configuration Protocol. A protocol for assigning dynamic IP addresses to network devices. With dynamic addressing, a device can have a different IP address every time it connects to the network. In some systems, the device's IP address can even change while it is still connected. DHCP also supports a mix of static and dynamic IP addresses.

Domain

A group of computers and devices on a network that are administered as a unit with common rules and procedures.
