Computer Network Tutorial

Modern world scenario is ever changing. Data Communication and network have changed the way business and other daily affair works. Now, they highly rely on computer networks and internetwork. A set of devices often mentioned as nodes connected by media link is called a Network. A node can be a device which is capable of sending or receiving data generated by other nodes on the network like a computer, printer etc.

Resource Sharing means to make all programs, data and peripherals available to anyone on the network irrespective of the physical location of the resources and the user. Reliability means to keep the copy of a file on two or more different machines, so if one of them is unavailable due to some hardware crash or any other them its other copy can be used. Communication Medium means one can send messages and whatever the changes at one end are done can be immediately noticed at another. The main objective of ARPANET was to develop a network that could continue to function efficiently even in the event of a nuclear attack.

The physical connection between networked computing devices is established using either cable media or wireless media. The best-known Computer Network is the Internet. This Tutorial will teach you basics of data Communication and Computer Network DCN and will also take you through various advance concepts related to data Communication and Computer Network.

A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes. The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network may include personal computers , servers , networking hardware , or other specialised or general-purpose hosts.

Data communication refers to the exchange of data between a source and a receiver via form of transmission media such as a wire cable. Data communication is said to be local if communicating devices are in the same building or a similarly restricted geographical area. The meanings of source and receiver are very simple.
