The bi-directional bus is the ____
A
Data bus
B
Instruction Bus
C
Control bus
D
Process bus
E
Address bus
Explanation: 

Detailed explanation-1: -A bidirectional bus buffer (transceiver) is a type of logic circuit whose I/O pins can be configured as input and output to receive and transmit data. Since a transceiver allows the signal direction to be changed via a control signal (DIR), it is used along a bus line through which data are transferred bidirectionally.

Detailed explanation-2: -Data bus is bidirectional because data flow in both directions, from microprocessor to memory or Input/Output devices and from memory or Input/Output devices to microprocessor.

Detailed explanation-3: -Data bus is Bidirectional because the Microprocessor can read data from memory or write data to the memory.

Detailed explanation-4: -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.
