<P> In computer architecture , A control bus is part of the system bus , used by CPUs for communicating with other devices within the computer . While the address bus carries the information about the device with which the CPU is communicating and the data bus carries the actual data being processed , the control bus carries commands from the CPU and returns status signals from the devices . For example , if the data is being read or written to the device the appropriate line ( read or write ) will be active ( logic one ) . </P>
