A mobile device (also known as a handheld device, handheld computer or simply handheld) is a small, hand-held computing device, typically having a display screen with touch input and/or a miniature keyboard and weighing less than 2 pounds (0.91 kg). Apple, HTC, Samsung, LG, Research in Motion (RIM) and Motorola are just a few examples of the many manufacturers that produce these types of devices.
A handheld computing device has an operating system (OS), and can run various types of application software, known as apps. Most hand held devices can also be equipped with WI-FI, Bluetooth and GPS capabilities that can allow connections to the Internet and other Bluetooth capable devices such as an automobile or a microphone headset. A camera or media player feature for video or music files can also be typically found on these devices along with a stable battery power source such as a lithium battery.
Early pocket sized ones were joined in the late 2000s by larger but otherwise similar tablet computers. As in a personal digital assistant (PDA), the input and output are often combined into a touch-screen interface.
Smartphones and PDAs are popular amongst those who wish to use some of the powers of a conventional computer in environments where carrying one would not be practical. Enterprise digital assistants can further extend the available functionality for the business user by offering integrated data capture devices like barcode, RFID and smart card readers.
Famous quotes containing the words mobile and/or device:
“From three to six months, most babies have settled down enough to be fun but aren’t mobile enough to be getting into trouble. This is the time to pay some attention to your relationship again. Otherwise, you may spend the entire postpartum year thinking you married the wrong person and overlooking the obvious—that parenthood can create rough spots even in the smoothest marriage.”
—Anne Cassidy (20th century)
“One good reason for the popularity of “reductionism” among the philosophical outposts of the Western Establishment is that it can be, and is, used as a device for trying to take the wind, so to speak, out of the sails of Marxism.... In essence reductionism is a kind of anti-Marxist caricature of Marxist determinism. It is what anti-Marxists pretend that Marxist determinism is.”
—Claud Cockburn (1904–1981)
