Electrical bus
An
electrical bus (sometimes spelled
buss) 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 PCss. See computer bus.
- Buses are used 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.
