(n.) In token-ring networks, the optional field at the end of a MAC header right before the user data that contains the routing information. Routing bridges use this data to determine where to route tokens when sending data from one token-ring network to another interconnected token-ring network. The routing information field typically contains a series of ring and bridge addresses that data will travel through to the final destination.
- routing protocol
A generic term that refers to a formula, or protocol, used by a router to determine the appropriate path over which data is transmitted. The routing protocol also specifies how routers in a network share information with each other and report changes. The routing protocol enables a network to make dynamic adjustments to its conditions, […]
- routing metric
A variable used by a dynamic router to calculate its routing table. This determines which route the router should use to forward a packet.
- routing switch
(n.) A switch that also performs routing operations. Usually a switch operates at layer 2 (the Data Link layer) of the OSI Reference Model while routers operate at layer 3 (the Network layer). Routing switches, however, perform many of the layer 3 functions usually reserved for routers. And because the routing is implemented in hardware […]
- row address strobe
Abbreviated RAS, a signal, or strobe, sent by the processor to a DRAM circuit to activate a row address. DRAM stores data in a series of rows and columns, similar in theory to a spreadsheet, and each cell where a data bit is stored exists in both a row and a column. A processor uses […]
(1) In word processing and desktop publishing, a straight line that separates columns of text or illustrations. (2) In expert systems, a conditional statement that tells the system how to react to a particular situation.
