Definitions for "Collision Domain"
Keywords:  collide, ethernet, csma, hub, segment
Collision domain is the portion of a network where all nodes receive every frame transmitted.
A LAN is a network which spans a limited geographical area. It is further described by the IEEE as a collision domain. A collision domain is a single CSMA/CD network which may consist of two or more Medium-Access Control (MAC) sublayers. MAC sublayers separated by a repeater are within the same collision domain. MAC sublayers separated by a bridge are within different collision domains. Splitting a hub or repeater into separate or multiple collision domains is often incorrectly referred to as "segmentation".
The maximum length of the wiring media that allows collision detection. For example, the collision domain in Fast Ethernet using 100BASE-TX is 205 meters.
