What does TABL stand for?

Tablet

A tablet is a flat, portable computer with a touchscreen interface. Early tablets required a stylus or light pen, but most modern tablets allow you to perform actions by simply tapping or swiping the screen. Some tablets allow you to use either your finger or a stylus as an input device. For several years, tablets had limited success. Then in 2007, the iPhone came along and popularized touchscreen devices. In 2010, Apple introduced the iPad, which brought tablets to the masses.
