CST 311 Week 2

CST 311 Week 2

This week was all about the application layer of the Internet protocol stack. Before this week I had a limited knowledge of HTTP, cookies, SMTP, and Peer to Peer. I learned that HTTP connections can be both persistent or non-persistent and the differences between the two. Before this week I understood the concept of cookies but did not know exactly how they worked. This week's lesson helped to expand my knowledge on the subject. Web caches can be used to make web browsing more efficient from the client end. The amount of "conversations" that occur for small amounts of data is neat to see with WireShark and a bigger appreciation for the application layer has been realized through my studies this week. We owe a lot to the scientists and researchers who have created this technology in which most people take for granted not knowing really what is involved behind the scenes in the various Internet networks.
