In data communications, a path for electrical transmission between two or more points. Coaxial Cable - Cable capable of carrying much higher bandwidth than copper wire due to its fabrication with one or more pairs in a single sheath. Typically, it consists of an outer conductor surrounding an inner conductor, separated from each other by insulating material. The transport of a single datagram or packet of information from one network node to a destination node or multiple nodes without establishing a network connection. Contention - The process whereby multiple users make requests for transmission bandwidth across a transmission link but the pool of bandwidth is less than the aggregate amount of bandwidth the users could request between them.
Contention is used to resolve which users gain access to the bandwidth.
When this is applied to multiplexers, it is concerned with the multiplexer's ability to allow a number of channels to contend for transmission bandwidth that is less than the sum of all the channel rates.
