A person using the touchscreen on a tablet computer.

A tablet computer (sometimes called a tablet) is a type of computer that can be carried easily. Unlike a laptop it has no physical keyboard or trackpad, though users sometimes add those things. Users control a tablet mostly by using its touchscreen with multi-touch technology similar to a smartphone. The screen can be anywhere from 7 inches (18 cm) (sometimes called a phablet) to 12 inches (30 cm) in size, but many have a screen size of about 10 inches (25 cm) diagonal.
