Computer Networking is the term associated with discipline of engineering. In a much broader way Computer Networking is the communication between computer systems. There are two more devices that are to be networked, one of which has to be a computer. The devices that are to be networked may be placed at a distance of few meters from each other if they are connected via Bluetooth and at infinite distance if they are connected by internet.
Computer Networking is also regarded as a sub-discipline of telecommunications, computer engineering, information technology, and computer science also. The theoretical and practical applications are the primary pillars of the Computer Networking studies.
The large areas of networks are done through internet, which covers the largest area that ever existed or ever will, whereas, in a small area the computer networking is done through local area network or LAN. In a small area like home or an office, the computers are connected through standard networking cables with the network interface card in each computer.
Computer networking is one of the most important and complex part of computing. Depending upon this most of the IT Industries is set up. There are three types of networking methods:
- Local Area Network (LAN): Compared to other networking systems, a much smaller area is connected through LAN.
- Wide Area Network (WAN): Via this system a large number of resources are installed across a wide domestic area or even internationally. May offices are interconnected with their overseas branches through WAN.
|
- Wireless Networks (WLAN, WWAN): This is same like the above two networking systems. The only difference is that no wires are used between servers and hosts.
