What is Token Ring? - a definition from Whatis.com - see also: 802.5 (532 words) |
 | - A Token Ring network is a local area network (LAN) in which all computers are connected in a ring or star topology and a bit- or token-passing scheme is used in order to prevent the collision of data between two computers that want to send messages at the same time. |
| The Token Ring protocol is the second most widely-used protocol on local area networks after Ethernet. |
| When a computer has a message to send, it inserts a token in an empty frame (this may consist of simply changing a 0 to a 1 in the token bit part of the frame) and inserts a message and a destination identifier in the frame. |

Token ring - definition of Token ring in Encyclopedia (1145 words) |
| Token ring is a local area network protocol which resides at the data link layer (DLL) of the OSI model. |
| Token ring networks had significantly superior performance and reliability compared to early shared-media implementations of Ethernet (IEEE 802.3), and were widely adopted as a higher-performance alternative to shared-media Ethernet. |
| A data token ring frame is an expanded version of the token frame that is used by stations to transmit medium access control (MAC) management frames or data frames from upper layer protocols and applications. |
