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:
types of network:
Local Area Network: The Local Area Network is also referred as LAN. This system spans on a small area like a small office or home. The computer systems are linked with cables. In LAN system computers on the same site could be linked.
Wide Area Network: A Wide Area Network or WAN is a type of networking where a number of resources are installed across a large area such as multinational business. Through WAN offices in different countries can be interconnected. The best example of a WAN could be the Internet that is the largest network in the world. In WAN computer systems on different sites can be linked
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.
Peer-to-peer networks: In this networking system all computers are given equal importance. All the software and data are stored on each computer and accesses to them are given to each user.
Server network: Also known as Client network, in this system, the data are not saved on each computer, rather saved on the server. Each user is enabled the facility of using the data and an access to the files on the server are also given.
