Best Answer

The bus allows the different devices inside the computer to communicate with each other. In reality, it is little more than several parallel 'traces' on the motherboard, but quite a bit of physical and logical hardware can be connected. Some motherboards can have multiple busses which can be used for different functions. A strictly controlled protocol is used for bus communication.

A bus is a set of "wires" on the motherboard which connect the CPU, RAM, expansion cards, NICs, modems, harddrives, floppy drives, etc.
