Which unit of the CPU directs and coordinates most of the operations in the computer ?

  • A.The arithmetic logic unit
  • B.The control unit
  • C.The register file
  • D.The cache

Answer: C

Correct answer: The control unit

The control unit fetches each instruction, decodes it and issues the signals that make the other components act. It performs no calculation itself, which is what distinguishes it from the arithmetic logic unit.
