The physical connection between network computing devices is established using cable or wireless media. The best-known computer network is the Internet.
This tutorial should teach you the fundamentals of data communication and computer network (DCN) and will also take you through several advanced concepts related to data communication and computer network.
This tutorial has been prepared for computer science graduates to help them understand the basics to advanced concepts related to Data Communication and Computer Networks. After completing this tutorial, you will encounter a moderate level of experience in Data Communication and Computer Networks from where you can take it to the next levels.
Before I start to follow with this tutorial, I am making an assumption that you are already aware of the basics of computer, such as what is the keyboard, mouse, monitor, input, output, primary and secondary memory memory etc. Are not aware of these concepts then I will suggest to go through our brief tutorial on Computer Basics.
