Detailed explanation-1: -The address bus is unidirectional . Data bus-carries the data between the processor and other components. The data bus is bidirectional .
Detailed explanation-2: -The address bus is unidirectional because the microprocessor addresses a specific memory location of the system. No outside devices can write into the Microprocessor. A data bus is bidirectional because the Microprocessor can read data from memory or write data to the memory.
Detailed explanation-3: -The control bus is bidirectional and assists the CPU in synchronizing control signals to internal devices and external components. It is comprised of interrupt lines, byte enable lines, read/write signals and status lines.
Detailed explanation-4: -Address bus is Unidirectional because the microprocessor is addressing a specific memory location. No outside devices can not write into Microprocessor. Data bus is Bidirectional because the Microprocessor can read data from memory or write data to the memory.
