In this chapter you will: Exploring different communication medium over which we can send data, understanding the issue of encoding bits onto transmission medium so that they can be understood by the receiving end, understanding the issue of encoding bits onto transmission medium so that they can be understood by the receiving end, discussing different technique to detect transmission errors and take the appropriate action. | Computer Networks: A Systems Approach, 5e Larry L.

How to connect two nodes together? We also introduced the concept of “cloud” abstractions to represent a network without revealing its internal complexities. How to connect a host to a cloud?
