A quad core processor in a computer consists of

  • A.2 CPU
  • B.4 CPU
  • C.4 ALU
  • D.None of the above

Answer: D

A quad core processor consists of 4 CPU.

'Quad' means four. A quad core processor has four independent processing units, called cores, on a single chip. Each core can fetch and execute instructions on its own, so it works as a CPU in its own right and four tasks can run at once.

Two CPUs would be a dual core processor. Each core contains far more than an arithmetic logic unit, so '4 ALU' describes only part of each core.
