Electrical bus

An electrical bus is a physical electrical interface where many devices share the same electric connection. This allows signals to be transferred between devices (allowing information or power to be shared). A bus often takes the form of an array of wires that terminate at a connector which allows a device to be plugged onto the bus.

  • Buses are used for connecting components of a computer: a common example is the PCI bus in PCs. See computer bus.
  • Buses are ysed for communicating between computers (often microprocessors). See computer bus.
  • Buses are used for distribution of electrical power to components of a system. The (usually) thick connectors used are called bus-bars[?].

See also distributed generation, Switched-mode power supply; SMPS.
