Laptops are small, compact computers that can easily be carried from place to place. Laptops combine the computer, monitor, and keyboard into a single unit, and they usually have a touchpad instead of a regular mouse.

Tablets or tablet computers are mobile computers that are larger than smartphones but smaller than laptops, though they function similarly. Tablets are flat and typically operate with a touch screen instead of a keyboard and mouse.
