collision domain

A physical region of a local area network (LAN) in which data collisions can occur.

Collisions are most likely in LANs, such as Ethernets, that use non-deterministic medium access control (MAC) protocols such as carrier sense multiple access with collision detection (CSMA/CD). See also CSMA/CD, Ethernet, LAN, MAC, and non-deterministic.
