Tablet (computer)

A tablet computer, commonly shortened to tablet, is a mobile PC, typically with a mobile operating system and LCD touchscreen display processing circuitry, and a rechargeable battery in a single thin, flat package. Tablets, being computers, do what other personal computers do, but lack some I/O capabilities that others have.

Tablets typically have other I/O capabilites that suit them to their usual tasks. These may include front-facing or rear-facing digital cameras, a microphone, GPS receiver, a flashlight, magnetometer, proximity sensor, hall effect sensor, gyroscope and an accelerometer, so images on screens are displayed upright, or to sense velocity. Some have a fingerprint sensor or iris scanner. Most tablets use Wi-Fi, and some can also use cellular networks, for Internet access. Tablets can run various software known as apps; most basic apps (such as camera, photos, web browser, voice/video calls, emails, text messages, maps, weather, calendar, contacts, notes, App Store, virtual assistant, etc) come pre-installed with the system. Others may be installed online from the app store.
