How does token ring work?
A token ring network uses a special frame called a token that rotates around the ring when no stations are actively sending information. When a station wants to transmit on the ring, it must capture this token frame. The owner of the token is the only station that can transmit on the ring, unlike the Ethernet topology where any station can transmit at any time. Once a station captures the token, it changes the token into a frame format so data can be sent. As the data traverses the ring, it passes through each station on the way to the destination station. Each station receives the frame and regenerates and repeats the frame onto the ring. As each station repeats the frame, it performs error checks on the information within the frame. If an error is found, a special bit in the frame called the Error Detection bit is set so other stations will not report the same error. Once the data arrives at the destination station, the frame is copied to the destination’s token ring card buffer memo
