Concept:The part of the computer that coordinates and directs all hardware operations is the control unit.
Explanation:The control unit is a key component of the central processing unit (CPU).
It fetches instructions from memory and decodes them.
It sends control signals to other hardware parts so they work in the correct order.
It manages the flow of data between the CPU, memory, and input/output devices.
This coordination ensures that all hardware components operate smoothly without conflicts.
The main memory stores data temporarily, and the arithmetic and logic unit performs calculations.
Only the control unit directs and supervises the whole processing operation.
Answer:B. Control unit
