mixed direction is when lines into micro processor and some other out of microprocesses.

Detailed explanation-1: -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-2: –Address bus (Unidirectional) carries #memory addresses from the processor to other components like primary #storage and #input/output devices.-#Data bus (Bidirectional) carries the data between the processor and other components.
Detailed explanation-3: -The address bus carries addresses and is a one-way bus from the microprocessor to the memory or other devices.
Detailed explanation-4: -Data bus is used to transfer data from one unit to another unit of the computer system. Microprocessor can read data from the memory or write data to the memory. So, the data bus is bidirectional.
