Learn Data Communication and Computer Network

数据通信与计算机网络教程

Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data. 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 Learn Data Communication & Computer Network 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 Learn Data Communication & Computer Network has been prepared for the computer science graduates to help them understand the basic to advanced concepts related to Data Communication and Computer Networking. After completing the Learn Data Communication & Computer Network 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.

Before you start proceeding with the Learn Data Communication & Computer Network, 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. If you are not well aware of these concepts then I will suggest to go through our short Learn Data Communication & Computer Network on Computer Fundamentals
