This part of a computer is like its busy brain, thinking very fast.
The processor is the correct answer because it acts like the computer's brain, following millions of instructions every single second to control everything the machine does, from opening an app to displaying a picture on the screen. It constantly does tiny calculations behind the scenes, even for things that look simple to us.
The screen just shows pictures and words, and the mouse pad is only a surface to slide a mouse across, neither one actually thinks or processes information, they just display or support other parts of the computer.
Modern processors can perform billions of calculations every second, which is part of why computers can play videos, run games, and answer questions almost instantly.
