Yes, you are right. Agree @S.V.Prasad.

Data bus and control bus are Bi directional.

In 8085 microprocessor, address bus is unidirectional and data bus is bidirectional.

What is the right answer?

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. Normally Control bus is unidirectional.

I think Data bus is not a bidirectional bus.

Data bus is bidirectional and address bus is unidirectional.

No, @Christhuraj data bus also takes inputs as a data as well as fetches memory hence they are bidirectional.

Hi, Actually data bus is used to carry data from memory only. So, how it could be bidirectional?
