  • Input devices such as a keyboard, mouse or scanner are used to enter input (data and/or instructions), directly into the computer.  
  • The CPU  is like the human brain; it has a memory and just like there is a faculty in the brain that regulates the functioning of all parts of the body, a computer has a control-unit (CU), which controls its entire operation    including its  input and output devices.  
  • Processing of data is done in the arithmetic and logic unit (ALU). It performs Arithmetic and logic operations such as addition, subtraction, multiplication and division. Here the word "Logic" is used because a computer (unlike a calculator) has the capacity to do logical operations also, such as compare two numbers, and find out which of the two numbers is greater.
