Features
-
The word "backplane" is often considered to be synonymous with a computer's motherboard. They control computing paths through socket connections not only to other circuit boards, but also to expansion cards and other electronic devices.
Backplanes are considered active if they contain circuitry that conducts computing functions. Passive backplanes do not contain circuitry and are not responsible for anything but serving as connectors.
