mobile computer with integrated display, circuitry and battery / From Wikipedia, the free encyclopedia
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.
Almost all tablet computers can access the Internet using Wi-Fi, and many can use mobile phone networks like 2G, 3G, 4G, and 5G. Like smartphones, many tablets have sensors such as a camera and a microphone. Other features tablets have are high definition, anti-glare (with less reflection) displays, a Bluetooth radio (to connect to printers and other devices), flash memory, and cloud storage services to back up information on the tablet and synchronize data.
Science fiction started putting tablets in stories after the middle 20th century. Some companies started making real tablets late in the century. The release of the Apple iPad in 2010 got much attention, and other companies made and sold more.
