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. Moving a finger over the touchpad controls the cursor just like moving a mouse over a desk.

Smartphones are mobile phones that are built like computers. They have more functions than feature phones, including Internet connectivity, and serve as mini computers.

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.
