Network - Channel

A channel is a physical or logical path for a signal transmission. Two particularly important channels in networking are the communications channel and the disk channel. A communications channel is a path through which data or voice can be transmitted; for example, in a network or a telephone call. In telecommunications, a single cable may be able to provide multiple channels. A disk channel, in a hard-disk configuration, consists of the components that connect a hard disk drive to an operating environment, such as DOS, OS/2, NetWare, or VINES. These components include cables and a hard disk adapter or controller. A single channel can accommodate multiple hard disks. A computer may have multiple disk channels. COMPARE Circuit
