Fundamentals of Datacom and Networking | 773 MB

In this course, we?ll begin by establishing a model for a data communications circuit, then provide examples and context for each of the components of the model, and review different circuit configurations including LANs and WANs.
In the second chapter, we?ll look at how data is formatted for transmission, beginning with the older concepts of ?synchronous? and ?asynchronous?, then cover the newer ideas of frames and packets, how frames and packets are related, and the addresses on frames and packets, and the structure of IPv4 packets.
We?ll complete this course with an understanding of the ?Network Cloud?, why people use clouds to draw networks, and what is really going on inside that cloud.
This set of topics, particularly the understanding of packets and frames, the addresses on each, and how they are related; and the idea that there are three kinds of network services ? and three kinds of edge equipment ? is the foundation for all further study of LANs, WANs, IP and just about any other kind of communications, including Voice over IP.
