Question

Which among the following allows the user to interact computer?

• A. Command line interface
• B. Graphical user interface
• C. Both options A and B
• D. None of these

Hint:

Remember that CLI uses text-based commands (like MS-DOS or Linux Terminal), while GUI uses visual elements (like Windows OS or macOS) for interaction.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
The question asks for the mechanisms or interfaces through which a human user can interact with a computer system.


Step 2: Detailed Explanation:
An interface acts as a boundary across which two independent entities meet and communicate.
In computing, a user interface allows a user to control a software application or hardware device.
A Command Line Interface (CLI) allows users to interact with the computer by typing text-based commands into a console or terminal.
A Graphical User Interface (GUI) allows users to interact with the computer using graphical elements like windows, icons, menus, and pointers.
Both CLI and GUI are standard and fundamental methods for human-computer interaction.


Step 3: Final Answer:
Since both Command line interface and Graphical user interface are correct, the right choice is "Both options A and B".
