Every computer device does one of three jobs. Input devices put information in (keyboard, mouse, microphone, scanner). Output devices give information out (monitor, printer, speakers). Storage devices keep it for later (hard disk, pen drive). Class 3 children learn to sort devices into these three groups.
What your child should know
- Input devices send information to the computer.
- Output devices show or give information from the computer.
- Storage devices save information to use later.
- Some devices, like a touchscreen, do both input and output.
