Backplanes are circuit boards that contain sockets or expansion slots for connections to other circuit boards. There two types of backplanes: active and passive.
Computer motherboards are printed circuit boards (PCBs) that house basic computer circuitry and vital components. They are devices into which other boards or cards are plugged.
Industrial chassis and card cages are metal frames that support and contain electronic components and power supplies. They generally have a backplane with slots to install other peripherals and accessories.
Single board computers (SBC) serve as the motherboard for instrumentation systems including modern PCs. SBCs are composed of a microprocessor, memory chip, and serial and parallel interfaces to communicate with other devices.
