Mobile Computing is a technology that allows transmission of data, voice and video via a computer or any other wireless enabled device without having to be connected to a fixed physical link.
Mobile may also refer to access in a fixed location via equipment that users can relocate as required, but is stationary while in operation. This mode of operation is often called nomadic computing.
The applications of mobile computing today have become ubiquitous and pervasive in business, consumer, industrial, entertainment and many specialized vertical-market activities. Desktop, or nonmobile, computers allow for a higher degree of hardware configurability or higher computational performance, but a mobile computing device is the vehicle of choice for almost every end user today. The key advantage of mobile computing is convenience, allowing users anytime, anywhere access to information and computational resources.
