Which microprocessor bus is not bidirectional?

Data bus
       Control bus
       Address bus
       Both B and C

How many clock pulses does an 8-bit successive-approximation ADC require to convert a
maximum input?

How many flip-flops are required to make a counter which counts from 0 to 28?

What is the modulus of a counter which counts from 0 to 4 and then recycles back to zero?

Solution

Address Bus is not Bidirectional it is Unidirectional as the microprocessor is addressing a specific memory location. No outside devices cannot write into Microprocessor.

We can also say that data bus is bidirectional because it transfers information between peripheral devices and memory register but, address bus is unidirectional because it simply receives the information.

We are allowed to answer only one Question at a time, so to get answers to the rest 2 Questions please post them separately.
