This tutorial should 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. Why to Learn Data Communication & Computer Network. Network Basic UnderstandingA system of interconnected computers and computerized peripherals such as printers is called computer network.

This interconnection among computers facilitates information sharing among them. Computers may connect to each other by either wired or wireless media. Network EngineeringNetworking engineering is a complicated task, which involves software, firmware, chip level engineering, hardware, and electric pulses.

To ease network engineering, the whole networking concept is divided into multiple layers. Each layer is involved in some particular task and is independent of all other layers. But as a whole, almost all networking tasks depend on all of these layers.
