Network Signals Cables Topologies 
In the
WestNet e-Learning module, we will consider the physical qualities of the network itself. We discuss the nature of electronic communication and explain how information can be transmitted as analog or digital signals. We then explore the various physical layouts or topologies of data networks, and show how the pattern of signal flow depends on the topology of the network.
