What is the work of the CPU?

The only work that the CPU does is that it processes the signals. Output devices like monitor, keyboard, and mouse are connected to the CPU. There is no direct connection between the keyboard and the monitor. But, whatever you type on the keyboard will appear on the monitor without any time lag. This is what CPU is doing each and every time. When you type a letter on the keyboard, the specific keystroke signal will reach the CPU. Then, it processes the signal and transfers it to the monitor, which will display the letter you typed.
