Mobile device

A portable electronic device designed for use while moving, typically combining computing functions with wireless connectivity.

System on a chip: An integrated circuit that combines a processor and other computer components on one chip. Combining processing and other functions in one package helps make mobile devices compact.
Mobile telephony: Telephone communication through cellular networks that connect mobile devices to one another and the wider telephone system. Cellular voice and messaging are foundational uses of portable connected devices.
Smartphone: A handheld mobile phone with an operating system that supports internet access and installable applications. It is the most familiar general-purpose form of mobile device.
Mobile internet: Internet access delivered to mobile devices through cellular or other wireless networks. It made online services available beyond fixed locations and wired connections.
Lithium-ion battery: A rechargeable battery that stores energy through lithium-ion movement between electrodes. Its rechargeable energy storage supports portable operation without a constant power connection.
Global Positioning System: A satellite-based navigation system that provides location and time information to receivers. A mobile device can use satellite signals to determine its location for navigation and location-aware services.
Tablet computer: A portable computer built around a touchscreen larger than that of a typical smartphone. Its larger display favors reading and media, while its size reduces pocketability.
Digital divide: Unequal access to digital technologies and the skills or resources needed to use them. Differences in device ownership, connectivity, and affordability shape who benefits from mobile services.
Wireless communication: The transmission of information between devices without a wired connection. Wireless links let mobile devices exchange data while users move between locations.
Mobile payment: A payment made using a mobile device, often through contactless communication or a digital wallet. Portable devices can act as payment credentials at shops and in online transactions.
