2. Keyboard
3. Mouse
4. Arithmetic and Logic Unit

Answer 1

Correct Answer - Option 4 : Arithmetic and Logic Unit

The correct answer is the Arithmetic and Logic Unit.

• Three main components of CPU -
  • There are three very special components in the CPU, namely Control Unit, Arithmetic Logic Unit, Registers (Memory Unit) respectively.
  • By whose contribution the processor is always implemented.

• ​Arithmetic logic unit -
  • ALU is a digital circuit in computer hardware,
  • The main function of an arithmetic logic unit is to perform arithmetic operations such as addition, subtraction, multiplication, division.
  • Apart from doing all the other tasks like mathematics, there are also logic-related tasks.
  • Like comparing, selecting, matching, merging data among themselves, this type of work is done by the Arithmetic Logic Unit (ALU).
  • The ALU is primarily designed for basic arithmetic operations.
• Printer -
  • ​It is a hardware output device that is used to generate hard copies and print any document.
