Microprocessor Fundamentals

Q1: The control bus and memories share a bidirectional bus in a typical microprocessor system.

A False

B True

ANS:B - False

Among 1)Address bus 2)Data bus 3)Control bus of a microprocessor.

Address bus is unidirectional as address is generated by microprocessor and is passed to i/o devices.

Data bus is bidirectional as data signal can flow from microprocessor to i/o devices, memory and from memory to i/o device.

Control bus is bidirectional as it transfer the control signals from control unit to all the i/o devices and vice versa.
