![]() ![]() Prerequisitesīefore you start proceeding with this tutorial, I'm making an assumption that you are already aware about basic computer concepts like what is keyboard, mouse, monitor, input, output, primary memory and secondary memory etc. After completing this tutorial you will find yourself at a moderate level of expertise in Data Communication and Computer Networking from where you can take yourself to next levels. This tutorial has been prepared for the computer science graduates to help them understand the basic to advanced concepts related to Data Communication and Computer Networking. Interaction with other users using dynamic web pages.Information sharing by using Web or Internet.Exchange of information by means of e-Mails and FTP.Resource sharing such as printers and storage devices.Applications of Communication & Computer NetworkĬomputer systems and peripherals are connected to form a network.They provide numerous advantages: To inter-connect various continents, fibers are laid under sea known to us as submarine communication cable. ![]() It uses Internet uses very high speed backbone of fiber optics. Internet enables its users to share and access enormous amount of information worldwide. Because of shortage of address spaces, it is gradually migrating from IPv4 to IPv6. Present day, Internet is widely implemented using IPv4. Internet uses TCP/IP protocol suite and uses IP as its addressing protocol. It is the largest network in existence on this planet.The internet hugely connects all WANs and it can have connection to LANs and Home networks. InternetĪ network of networks is called an internetwork, or simply the internet. Layers share data between them and they depend on each other only to take input and send output. But as a whole, almost all networking tasks depend on all of these layers. Each layer is involved in some particular task and is independent of all other layers. To ease network engineering, the whole networking concept is divided into multiple layers. Networking engineering is a complicated task, which involves software, firmware, chip level engineering, hardware, and electric pulses. Computers may connect to each other by either wired or wireless media. This interconnection among computers facilitates information sharing among them. Why to Learn Data Communication & Computer Network? Network Basic UnderstandingĪ system of interconnected computers and computerized peripherals such as printers is called computer network. 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. The best-known computer network is the Internet. The physical connection between networked computing devices is established using either cable media or wireless media.
