Networking concept is widely used in various fields and technologies. Network is an arrangement of intersection horizontal and vertical lines like a structure of a net. A group of points are integrated for various reasons. This concept has been implemented in all technologies. The technologies such as computer systems, telecommunication, mobile cell, information, television, radio, internet, intranet, extranet are advanced because they adopted integration.
The computer systems are most powerful machines in the present world that can be networked in different environment in different situations. Networking in the field of computing is the practice of linking computers together to support digital communication among them. Local Area Network (LAN), Wide Area Network (WAN), Metropolitan Area Networks (MAN), Wireless LAN, Intranet, Internet, and extranet. The client-to-client and server-to-client technology are the basic concept of advanced computer network. As a result, a chain of interconnected computers machines or operations are taken place. Computer networking companies manufacturing network devices for establishing robust networking. The research and development on the technologies create demand of network hardware and devices. Wireless networking and virtual networking is the latest network technologies are going to provide better services to the world.
