Quiz: Computer- 3 - Question 4

Which part of computer system accepts input from the user?

Detailed Solution for Quiz: Computer- 3 - Question 4
Which part of computer system accepts input from the user?

The part of the computer system that accepts input from the user is the Input Unit.


Explanation:


Here is a detailed explanation of the answer:



  • Input Unit: This is the component of the computer system that allows users to input data and instructions into the computer. It acts as an interface between the user and the computer.

  • Examples: Some common examples of input devices that are part of the input unit include keyboards, mice, touchscreens, scanners, and microphones.

  • Function: The input unit converts the user's input into a form that can be understood by the computer. It then sends this information to the central processing unit (CPU) for further processing.

  • Importance: The input unit is crucial for enabling users to interact with the computer system and provide the necessary input for various tasks and operations.


Therefore, the correct answer is Option A: Input Unit.


Remember that the input unit is responsible for accepting input from the user, while the output unit is responsible for displaying or outputting information to the user. The control unit, on the other hand, is responsible for coordinating and controlling the activities of the computer's hardware components.
