Introduction to the Data Bus and How They Communicate

the data bus is a way for multiple lines (wires) communicate in a simultaneous fashion. For example, a data bus for 4 bit or 8 bit communication would have 4 or 8 wires respectively. The wires would be carrying 4-bit or 8-bit information. Each 4 or 8 bit communication is happening on all of the wires at the same time.
