A network standard invented by IBM and later defined by the 802.5 subcommittee of the IEEE which provides for a network with a star ring topology, and which operates by passing a token frame around the logical ring
A type of LAN in which networked computers are wired into a ring Each computer (or node) is in constant contact with the next node in the ring A control message, called a token, is passed from one node to another, allowing the node with the token to send a message out to the network If the ring is "broken" by one computer losing contact, the network can no longer communicate The IEEE 802 5 token ring standard is the most common
A type of LAN in which networked computers are wired into a "ring " Each computer (or node) is in constant contact with the next node in teh ring A control message, called a "token" is passed from one node to another, allowing the node with the token to send a message out to the network If the ring is "borken" by one computer losing contact, the network can no longer communicate The IEEE 802 5 token ring standard is the most common
A networking hardware system developed by IBM Constructed as a ring of daisy chained nodes Each node passes a control message (token) around the ring Whichever node has the token can send a message
A 4 to 16 Mbps (million bits per second) network, developed by IBM, that uses a ring topology, where the nodes are attached in a closed loop, and a token-passing method which allows each node in turn time to transmit
network communications architecture in which only the workstation which currently has the token may transmit data (token = continuous control message which is transmitted from station to station)
People often use the term "Token Ring" to designate IEEE 802 5 (see above) In the more general sense of the phrase, a token ring is a type of LAN that has stations wired in a ring, where each station constantly passes a special message (a "token") on to the next Whoever has the token can send a message
A popular local area network (developed by IBM) that uses a token-passing media access method over a star topology Also used to refer to the standard specified by IEEE 802 5
A computer local area network arbitration scheme in which conflicts in the transmission of messages are avoided by the granting of "tokens" which give permission to send A station keeps the token while transmitting a message, if it has a message to transmit and then passes it on to the next station Often, "Token Ring" is used to refer to the IEEE 802 5 token ring standard, which is the most common type of token ring Token Ring is 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
A token ring is a type of LAN with nodes wired into a ring Each node constantly passes a control message (token) on to the next; whichever node has the token can send a message Often, "Token Ring" is used to refer to the IEEE 802 5 token ring standard, which is the most common type of token ring See also: Local Area Network
A type of network with nodes wired into a ring Each node constantly passes a control message (token) on to the next; whichever node has the token can send a message Often, "token ring" is used to refer to the Institute of Electrical and Electronics Engineers (IEEE) 802 5 token ring standard, which is the most common type of token ring See also local area network
A token ring is a kind of LAN that consists of computers that are wired into a ring Each computer is constantly in direct contact with the next node in the ring A token, which is a type of control message, is sent from one node to another, allowing messages to be sent throughout the network A Token Ring network cannot communicate within itself if one ring is broken
A network medium developed by IBM in which each computer in the ring passes a token, which carries network messages, to the adjacent computer Token Ring provides each computer on the ring with guaranteed capability to transmit at regular intervals; Ethernet doesn't provide such a guarantee Token Ring is specified by the IEEE-802 5 standard See Ethernet
A type of local area network where all workstations and devices are connected in a star or ring topology A token travels around the ring, a workstation catches the token, attaches its message if it has one to send, and then lets the token go to continue around the ring
A message-passing method that controls traffic within some ring topology networks A set number of empty "boxes," called tokens, circulate around the ring, coded with an availability signal When a node wishes to send data, it puts the addressed information in the nearest available token As in all ring networks, the data travels around the ring until it finds a node with a matching address Once the data is delivered, the empty token is returned to the ring
A medium-speed token passing LAN hardware standard developed by IBM; very similar to IEEE 802 5 LANs, which are also sometimes referred to as "token ring LANs"
A ring network allowing unidirectional data transmission between stations by a token-passing procedure; also a network using a ring topology, in which tokens are passed from node to node A token is a packet of information transmitted over a computer network
A ring topology for a local area network (LAN) in which a supervisory frame, or token, must be received by an attached terminal or workstation before that terminal or work-station can start transmitting The workstation with the token then transmits and uses the entire bandwidth of whatever communications media the token ring network is using A token ring can be wired as a circle or a star, with the workstations wired to a central wiring center, or to multiple wiring centers The most common wiring scheme is called a star-wired ring Whatever the wiring, a token ring LAN always works logically as a circle, with the token passing around the circle from one workstation to another The advantage of token ring LANs is that media faults (broken cable) can be fixed easily, since its easy to isolate the faults Token rings are typically installed in centralized closets, with loops snaking to served workstations
An IBM LAN-based LAN protocol that uses a ring-shaped network topology Token Ring has speeds of 4Mbps and 16Mbps A distinguishing packet is transferred from machine to machine and only the machine that is in control of the token is able to transmit
IBM's network protocol Theoretically higher performance under heavy load than Ethernet because it is deterministic (no collisions possible), but it has more overhead In practice it didn't show enough performance advantage to offset its considerably higher price Token Ring comes in 4-mbs and 16-mbs versions Network cards are cabled to a MAU (Media Access Unit) A "token" is passed from card to card around the ring, and only the card holding the token is allowed to send data onto the network cable
