A '''mobile device''' or '''handheld device''' is a computer small enough to hold and operate in hand. Mobile devices are typically battery-powered and possess a [[flat-panel display]] and one or more built-in [[input device]]s, such as a [[touchscreen]] or [[keypad]]. Modern mobile devices often emphasize [[wireless network]]ing, to both the [[Internet]] and to other devices in their vicinity, such as headsets or [[in-car entertainment]] systems, via [[Wi-Fi]], [[Bluetooth]], [[cellular network]]s, or [[near-field communication]].<ref>{{cite book | last=Iversen | first=Jakob | author2=Michael Eierman | date=2014 | url=https://books.google.com/books?id=B6lKAgAAQBAJ | title=Learning Mobile App Development: A Hands-on Guide to Building Apps with IOS and Android | publisher=Addison-Wesley | page=3 | isbn=978-0-321-94786-4 | via=Google Books}}</ref>
