Which component of a computer is called as its “heart”?

  • (A) Monitor
  • (B) Keyboard
  • (C) Scanner
  • (D) Microprocessor
The microprocessor, or CPU (Central Processing Unit), is thought to be the "heart" or "head" or "brain" of a computer, as it does all the necessary functions to make the computer work. It executes software program instructions, processes data and performs arithmetic and logical calculations. It also controls the flow of data from internal hardware, like memory, to external hardware such as input and output devices. Just as a human heart supplies blood to keep a body alive, the microprocessor continually transmits, distributes, and directs data and signals throughout the computer so that all the components of the computer work together effectively.
