11.5 Summary of Session 11

In this session you have seen how today’s data transmission technologies are the result of an evolutionary process and why the encapsulation of data units enables a message to be carried over a variety of different networks. You have revisited IP addressing and subnet masks, and you have practised configuring and testing a simple network using Packet Tracer Anywhere.
