Which of the following describes the role of the Central Processing Unit?

• A. Receives information and carries out commands.
• B. Stores data.
• C. Displays graphics.
• D. Sends data to the user.

Answer: (A)

The main idea here is what the CPU does in a computer. The CPU acts as the brain, pulling instructions from memory, figuring out what they mean, and carrying them out. It uses the control unit to orchestrate actions and the arithmetic logic unit to perform calculations, effectively moving data around, making decisions, and directing other parts of the system based on those instructions. This role explains the phrase “receives information and carries out commands”—the CPU takes in instructions, processes them, and drives the next steps in the computer’s operation. Data storage is handled by memory and storage devices, graphics are produced by the GPU and display system, and sending results to the user involves output devices. So the CPU’s job is to process instructions and control data flow, not to store data permanently, render graphics, or directly present output to the user.
