Peripherals are elements of communication between the computer and the outside world (including ourselves).

Entry peripherals

-Entry peripherals give information to the computer: keyboard, mouse, microphone, thermostat ...

-Exit peripherals

The computer uses the exit peripherals to give information to us or to an actuator: screen, speakers, printer, light bulb, motor...
