1. A tablet, tablet computer, or tablet PC is a mobile computing device designed to be held in one or two hands. It is approximately the size of a hardcover book (seven inches or bigger), and resembles a large smartphone. The picture is an example of the ASUS Nexus 7 Android tablet.
Tablets let you do many of the same things as a traditional computer. They can browse the Internet, connect to social network apps, and display HD videos. They excel at applications that do not require a large amount of precise user input.
Early tablet devices used light pens or a stylus as their input device. However, today all tablets use a touch screen as their primary input device with the option to connect external devices, such as a keyboard. Most tablets only have a few physical buttons; the back, power, and volume buttons. Everything else can be done using your fingers.
Today, the top two operating systems used with tablets is Apple iOS used with iPads and Google Android used with Android tablets. A tablet can have apps installed on it to perform a function. For example, the Safari app on iPads is the browser that allows you to browse the Internet. On Android tablets, the Chrome app is often the default browser.
