Data and Address Buses
Every bus is composed of two distinct parts: the data bus and the address bus. The data bus is what most people refer to when talking about a bus; these are the lines that actually carry the data being transferred. The address bus is the set of lines that carry information about where in memory the data is to be transferred to or from.
In addition, there are a number of control lines that, well, control how the bus functions, and allow users of the bus to signal when data is available. These are sometimes refered to as the control bus, though often they are simply not mentioned.
