Answer / m.noman shahid

Data bus is bidirectional. It carries data among CPU, MEMORY and other HARDWARE DEVICES on motherboard. It makes path for two-way transfer of data as you know data travels from one unit such as MEMORY to another as CPU and also it comes back from CPU to MEMORY.


Address busis unidirectional.CPU addresses the MEMORY because it controls the computer but but MEMORY can't because it has not authority to address any unit.
