MOBILE COMPUTING
TECHNOLOGIES
is a type of human-computer interaction in which a computer is intended to roam during typical operation.
A technique that permits data, voice, and video to be sent wirelessly from a computer or other wirelessly equipped device without the need for a fixed physical link.
Mobile Communication
refers to a type of communication in which the sender and receiver do not have to be physically connected and can travel from one physical location to another while communicating.
Mobile Hardware
This category includes mobile devices or device components that receive or access mobility services. These gadgets will be equipped with a signal-sensing and-receiving receptor media.
Mobile software
