Mobile device

A mobile device is a small computing device, typically small enough to be handheld (and hence also commonly known as a handheld computer or simply handheld), having a display screen with a miniature keyboard (either alphabetic, numeric or alphanumeric) and, in some models, a touchscreen which enables the user to use a “virtual keyboard” that is displayed on screen, along with other icons and “buttons” that can be pressed. Mobile devices typically weighing less than 2 pounds (0.91 kg). A handheld computing device has an operating system (OS), and can run mobile apps. In the 2010s, most handheld devices are also equipped with Wi-Fi, Bluetooth, near field communication (NFC) capabilities and Global Positioning System (GPS) capabilities.
