What is a Network?
... The Token Ring protocol was developed by IBM in the mid-1980s. The access method used involves tokenpassing. In Token Ring, the computers are connected so that the signal travels around the network from one computer to another in a logical ring. A single electronic token moves around the ring from o ...
