A term for the electrical pathways inside a computer, along which signals are sent from one part to another. For example, there is a data bus, an address bus, a control bus, and an expansion bus. There are also external busses, where you can attach peripherals or additional devices. These buses include parallel and serial ports, PCI slots, and SCSI ports. A backbone is a network bus that connects all computers into a single network.
