The origins of mobile computing can be traced back to the gradual spread of personal computers, in turn linked to the technological advances that have led to a progressive reduction in the size of the hardware. The category of laptops has undergone a rapid development in recent decades, giving rise to a large class of categories of computers such as laptops, notebooks, tablet PCs, up to the handhelds.

A mobile data terminal (MDT) or mobile digital computer (MDC) is a portable device for mobile data processing and exchange. This includes smartphones, tablets, and other devices to communicate with a central dispatching used in commercial vehicles.

It has a screen that shows the information sent by the central or entered on the keyboard of the computer or terminal keyboard, but it can just as easily be connected to different devices. Standard devices are GPRS modem and a taximeter, all for attending the dispatching computer.

In the past, TDM equipment were tailored to specific needs and connected by radio. With the generalization of dispatching services, standardized products began to appear, sometimes abandoning the radio communication for IP communication directly on wireless networks.

At the same time, the spread of wireless technologies to connect to the Internet and networking has helped facilitate the use of these tools for transmitting and receiving data by App Developers in VA. This new scenario has contributed to the advent of a new generation of computing devices that emphasize miniaturized network access, such as netbooks and MIDs (mobile Internet devices).

Terms such as pervasive computing or ubiquitous computing have been recently coined to indicate the possibility of access to the network and storage systems and data processing in virtually all contexts and through a variety of devices.

Applications

In addition to reducing the overall geographical constraints in access to data and programs, mobile computing promotes the development of specific applications. Mobile commerce (e-commerce applications accessed through mobile devices), for example, can take advantage of technologies such as GPS and map databases to evolve in location-based commerce, which is a form of e-commerce based on the following principles: location: possibility of determining the position of a person.

Navigation: possibility to trace a path from one location to another. Tracking: monitoring the movement of a person or thing. Mapping: creating maps of specific geographic locations and timing: temporal determination of the coordinates of an event in a given location. Another area where there is a strong evolution is health, or the applications of mobile computing earmarked to the medical profession.

MDD is often connected to a black box that contains a GPS receiver, a portable transmitter phone or other wireless tools. Some are even equipped with an operating system, Windows CE often with such applications the integrator.
