Tablets are portable computers, usually Internet-enabled, which are similar to a smartphone. They usually have touch-screen technology. The screen is usually about 20 inches (25 cm) though smaller ones are also common and larger 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 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).

Some advantages of tablets are that they are highly portable, have long battery life, have a low weight, generate less heat, allow the user to still get notifications when the tablet is powered off or on standby, and don't need a mouse or keyboard to be attached to use their features.

Some disadvantages are that the virtual keyboards are sometime slow and error-prone, tablets have limited data storage compared to a laptop, and they usually do not support as many file formats and different types of software as laptops.
