- Electrical bus
An electrical bus (sometimes spelled incorrectly as "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 aconnector which allows a device to be plugged into 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 used for communicating between computers (oftenmicroprocessor s). See computer bus.
* Buses are used for distribution of electrical power to components of a system. The (usually) thick conductors used are calledbusbar s. In an electrical laboratory, for example, a bare bus-bar will sometimes line the wall, to be used by the engineers and technicians for its highelectric current -carrying capacity, which allows a convenient approximation to "zero voltage", or "ground" in the US, and "earth" in the UK.
* In analysis of an electric power network a "bus" is any node of the single-line diagram at whichvoltage , current, power flow, or other quantities are to be evaluated. These may or may not correspond with heavy electrical conductors at a substation.
* Inpro audio , "bus" refers to a place in the audio signal chain where one can hear a mix of different audio signals—usually at the output of a mixer, or as a separate sub-mix within the mixer (for example all of the microphones used to capture adrum kit ). Sometimes it is used interchangeably with the noun "mix".See also
