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 –
