token bus network
A type of local-area network (LAN) that has a bus topology and uses a token -passing mechanism to regulate traffic on the bus. A token bus network is very similar to a token ring network, the main difference being that the endpoints of the bus do not meet to form a physical ring. Token bus networks are defined by the IEEE 802.4 standard.

- Token
)(1) In programming languages, a single element of a programming language. For example, a token could be a keyword, an operator, or a punctuation mark. (2) In networking, a token is a special series of bits that travels around a token-ring network. As the token circulates, computers attached to the network can capture it. The […]
- token passing
A type of CAM. Token passing uses a token, or series of bits, to grant a device permission to transmit over the network. Whichever device has the token can put data into the network. When its transmission is complete, the device passes the token along to the next device in the topology. System rules in […]
- Token-Ring Network
)(1) 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.
- toner
A special type of ink used by copy machines and laser printers. Toner consists of a dry, powdery substance that is electrically charged so that it adheres to a drum, plate, or piece of paper charged with the opposite polarity. For most laser printers, the toner comes in a cartridge that you insert into the […]
