Data Networking includes the root of networking protocols and it is a collection of interconnected communications. The design of the communication channel leads to the current and the future customer needs. This is related with the layered architectures, the Internet, and the OSI model.

Data networking works while transfer data between the nodes. This is possible only through switching, system control and interconnection transmission lines. The transfer and reception of data take place in the form of spreadsheets, letters, and other document types.The main difference from other type of communication is that data networking is  configured to transfer data only.

 Data networking provides the transmission of computer information. It may be voice,video, or other format. Also the transmission is possible through nodes or stations, this is connected through various communication channels.
