IBM's implementation of the token-ring network architecture; it uses a token-passing protocol transmitting at 4 or 16 mbps. Using standard telephone wiring, a Token Ting network can connect up to 72 devices; with shielded twisted-pair wiring, the network can support up to 260 nodes.
A local area network configuration that forms a closed ring of machines where network traffic is managed through the passing of digital tokens. A machine on the network cannot send data unless it "has the floor" via the token. A token ring can operate at up to 4 megabits (4 million bits) per second.
a 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
a local area network in which all computers
a network in which all the computers are connected in a circular pattern
a protocol defined by IBM in which data travels in a logical "ring" throughout the network
A physical ring network topology. On a token ring network, data moves around the entire ring, from one workstation to the next, eventually receiving the transmitted information back after it completes one round trip around the ring. The token, a specific bit sequence that circulates around the nodes, gives permission to transmit.
A type of ring network that constantly circulates an electronic signal, called a token, around the network, that allows devices on the network to send messages by taking the token and attaching it to data. 6.31
A token ring network is a type of local area network. In a token ring network, all workstations are connected in a ring or star topology and a token-passing scheme is used to prevent the collision between two workstations who want to send messages at the same time.
A ring network developed by IBM in which each hardware component receives the right to use the network by means of a token. When a hardware component possesses the token, it has the exclusive right to transmit to another hardware component in the network. Token Ring networks use TCP/IP protocols to pass a special bit pattern (token) from node-to-node to indicate which device can transmit data on the network. See Ethernet.
A baseband networking system that operates over shielded twisted-pair copper wires, using a ring topology and token passing access protocol. The original protocol developed by IBM was succeeded by the IEEE 802.5 standard for token ring network communications. Can be run at 4 Mb/s or 16 Mb/s. See also 802.5, Ethernet, LAN.
n. A local area network formed in a ring (closed loop) topology that uses token passing as a means of regulating traffic on the line. On a token ring network, a token governing the right to transmit is passed from one station to the next in a physical circle. If a station has information to transmit, it "seizes" the token, marks it as being in use, and inserts the information. The "busy" token, plus message, is then passed around the circle, copied when it arrives at its destination, and eventually returned to the sender. The sender removes the attached message and then passes the freed token to the next station in line. Token ring networks are defined in the IEEE 802.5 standards. See also IEEE 802 standards, ring network, token passing. Compare token bus network.
n. A token-passing, ring-shaped local area network developed by IBM that operates at 4 megabits (4 million bits) per second. With standard telephone wiring, the Token Ring network can connect up to 72 devices; with shielded twisted-pair (STP) wiring, the network supports up to 260 devices. Although it is based on a ring (closed loop) topology, the Token Ring network uses star-shaped clusters of up to eight workstations connected to a wiring concentrator (Multistation Access Unit, or MSAU), which, in turn, is connected to the main ring. The Token Ring network is designed to accommodate microcomputers, minicomputers, and mainframes; it follows the IEEE 802.5 standards for token ring networks. See also ring network, STP, token passing.
