Token Ring
Noun · Development
Definitions
A LAN protocol (IEEE 802.5) in which networked stations are arranged in a logical ring and a special 'token' frame circulates continuously — a station may only transmit data when it holds the token, preventing collisions but largely supplanted by Ethernet.
In plain English: An older networking method where computers take turns sending data by passing around a digital 'permission slip' in a circle.
Example: "The building still had token ring cabling from the '90s — we ripped it all out and ran Cat6."
