What is the central processing unit (CPU)?

  1. The component of a computer responsible for storing and processing information

  2. The part of the computer responsible for displaying information to the user

  3. The part responsible for inputting commands

  4. A peripheral device

The correct answer is: The part of the computer responsible for displaying information to the user

The central processing unit (CPU) is responsible for carrying out the instructions of a computer program. Option A is incorrect because while the CPU does process information, it does not store it. That is the function of the computer's memory. Option C is incorrect because the part responsible for inputting commands is the input device, such as a keyboard or mouse. Option D is incorrect because a peripheral device is any external device connected to the computer, such as a printer or scanner, and is not part of the CPU. Option B is the correct answer because the CPU is the "brain" of the computer and is responsible for performing calculations and making decisions based on instructions from the computer program.
