2.1.3 - Media Access Control and Collision Domains

Flashcards covering key concepts related to Media Access Control and Collision Domains based on lecture notes.

Media Access Control (MAC)

Methods used by a network technology to determine when nodes can communicate on shared media.

Collision Domain

A network segment where only one device can transmit at a time, and all other devices must wait.

Contention-based MAC system

A media access control system where nodes compete for the opportunity to transmit.

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

An Ethernet protocol that manages contention and media access while detecting collisions.

Collision

The state where two signals are present on an interface's transmit and receive lines simultaneously.

Jam Signal

A broadcast signal sent by a node after detecting a collision to notify other nodes.

Backoff

The random period that nodes wait before attempting to transmit again after a collision.

Half-duplex transmission

A communication mode where a node can either transmit or receive, but not both at the same time.

Ethernet Hub

A device that connects multiple Ethernet nodes and repeats incoming signals to each connected node.
