Definition

A parallel interface (as distinguished from a serial interface) is one in which data is sent on several wires (or several wireless channels) at once. Examples: GPIB, byte-wide parallel interfaces to data converters, memory and data buses on computer boards and backplanes.

In contrast, a serial interface uses one wire or wire-pair or wireless channel (or one in each direction).
