Application
As a communication service, data communication provides services for realizing generalized telematics processing. With the increasingly widespread use of computers and various intelligent devices with processing functions in various fields, the application scope of data communication is also expanding day by day. Its typical applications include: file transmission, e-mail, voice mail, visual graphics, directory search, intelligent user Telegraph, telemetry and remote control, etc. For each specific application, the communication functions related to the application must be implemented in the telematics system or the computer network accordingly, and these functions are also regulated in the form of tiering arrangement.

Development Trend
The development trend of data communication is shown as follows:
1. With the expansion of application scope and scale, new application services such as electronic data interchange (EDI) and multimedia communication are constantly emerging.
2. With the increase of traffic, the network is increasingly developing towards high speed, broadband, digital transmission and comprehensive utilization. For example, many new technologies such as optical fiber high-speed local area network, metropolitan area network, broadband integrated service Digital Network, relay, fast packet switching and so on have developed rapidly, and some have entered the practical stage.
3. With the development of mobile communication, mobile data communication is developing rapidly.
4. With the continuous expansion of network and system scale, the importance of interconnection between different types of networks and systems (including the operation and management of interconnected networks) has become increasingly prominent.
5. Communication protocol standards are increasing greatly, and protocol engineering technology is developing day by day.
