Tablet computer

From Wikipedia, the free encyclopedia

Tablets are portable computers, usually Internet-enabled, which are similar to a smartphone. They usually have touch-screen technology. The screen is usually about 10 inches (25 cm), though smaller ones are also common, and larger tablets are not rare. Most use a virtual keyboard rather than a physical one. Internet-access can be done by Wi-Fi or by mobile phone networks like 2G, 3G, and 4G. Sensors often include a camera and a microphone. Features of tablets may include high definition, anti-glare displays, Bluetooth connectivity to printers and other devices, and flash memory and cloud storage facilities to back up and synchronize data.

Tablets that are designed as a hybrid between tablets and smartphones are often called phablets. They are generally bigger than the smartphones, but are smaller than tablets (about 12 cm to 15 cm).

Compared to laptop computers, tablets are lighter and more portable, have longer battery life, generate less heat, and don't need a mouse or keyboard to be attached to use their features. Most allow the user to get notifications even when the tablet is powered off or on standby.

Some disadvantages are that the virtual keyboards are sometimes slow and error-prone, and tablets often have limited data storage compared to a laptop. Most run a Mobile operating system and often do not support as many file formats and different types of software as laptops.
