Backplane

A backplane is a group of electrical connectors that work in parallel with each other. This means that each pin of these connectors are linked to the same relative pin of the other connectors – the result is a computer bus. A backplane is considered to be the backbone which connects several printed circuit boards together forming a complete computer system. Not to be confused with the motherboard, a backplane is differentiated by the lack of on-board processing and the various storage elements. Types of backplanes include PICMG 1.3, PICMG 1.0, PICMG 1.1, and PICMG 1.2. Backplanes are used in servers in a wide range of applications including both in the domestically and commercially.
