A backplane (or "backplane system") is a group of electrical connectors in parallel with each other, so that each pin of each connector is linked to the same relative pin of all the other connectors, forming a computer bus. It is used as a backbone to connect several printed circuit boards together to … See more
Early microcomputer systems like the Altair 8800 used a backplane for the processor and expansion cards.
Backplanes are normally used in preference to cables because of their greater See moreWhen a backplane is used with a plug-in single-board computer (SBC) or system host board (SHB), the combination provides the same functionality as a motherboard, … See more
Servers commonly have a backplane to attach hot swappable hard drives; backplane pins pass directly into hard drive sockets without cables. They may have single connector to connect one disk array controller or multiple connectors that can be connected … See more
Backplanes have grown in complexity from the simple Industry Standard Architecture (ISA) (used in the original IBM PC) or S-100 style where all the connectors were connected to a common bus. Due to limitations inherent in the Peripheral Component Interconnect See more
Some backplanes are constructed with slots for connecting to devices on both sides, and are referred to as midplanes. This ability to plug cards into either side of a midplane is often useful in larger systems made up primarily of modules attached to the … See more
