Question: 1 / 50

What is the central processing unit (CPU)?

The component of a computer responsible for storing and processing information

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.
