contention The condition which sometimes occurs in some LOCAL AREA NETWORKS where two devices connected to a network are allowed to transmit data at the same time; when this condition holds there is a probability that a COLLISION will occur. There are a number of strategies that are used to avoid or recover from this condition. For example, each of the senders may be delayed for a different, random time period before resending.

con·ten·tion / kənˈtenchən/ • n. 1. heated disagreement: the captured territory was one of the main areas of contention between the two countries. 2. an assertion, esp. one maintained in argument: statistics bear out his contention that many runners are undertrained for this event. PHRASES: in contention having a good chance of success in a contest.

contention A situation in which several independent activities simultaneously seek access to the same resource, as when several independent transmitters wish to send data across a single communication channel. Where contention may arise, it is necessary to provide some form of arbitration to determine which activity gains access to the resource.
