Token Ring

 

Token Ring Our Definition Sources and Online Definitions

 

Our Definition   A network topology has a ring shape or, commonly, a star shape if there is a special central device. Connection between computers is serial and unidirectional. A token is passed from computer to computer around the circle. A computer catches the token, attaches a message to it, and releases it in order to send a message to another computer in the token ring.

"A type of computer network in which all the computers are arranged (schematically) in a circle. A token, which is a special bit pattern, travels around the circle. To send a message, a computer catches the token, attaches a message to it, and then lets it continue to travel around the network."

 

 

Smart Computing

"In a token-ring network, the stations are connected to one another either in a ring format, where each computer is connected to the next computer, or in a star format, where each computer connects to a central device, using an MSAU (multistation access unit). The second approach is far more common and offers more flexibility.

"Regardless of how the stations are connected physically, logically they are connected to each other serially so that station 1 connects to station 2, station 2 connects to station 3, and so on until the last station connects back to the first station. When connected via an MSAU, stations that stop responding can be switched out of the network loop and new stations can be inserted into the network loop as required. Shielded or unshielded twisted-pair cable is used to make the connections. A token-ring network can operate at either 4Mbps (megabits per second) or 16Mbps."
