Meaning – A channel is defined as a path along which a signal travels. It is known that a signal usually has one origin and a single or multiple destinations. The path that the signal takes, to go from the source to the destination/destinations, is known as the channel. Some of the commonly known channels include data channel and output channel.

In the context of computers, a channel is a functional unit, controlled by the processor, that handles the transfer of data between processor storage and local peripheral equipment.

Alternatively, a channel is also a means of one-way transmission, in the context of data communication.

Example of usage“The engineer was tasked with monitoring the channel to spot any losses in the signal.”
