CST 311 - Week 2

Chapter 2 covered the application layer and HTTP, which is the application layer protocol. This chapter helped us to get a better understanding of how data is transferred over the web and the key differences between non-persistent and persistent HTTP. The chapter also covered SMTP, the protocol concerning e-mail and DNS, or the web's domain name system. This was especially interesting to me to see how a computer handles web site information needing to be both computer and human-readable.

We also dove more into Wireshark and how to expand the query and response messages in order to get information. Worksheet 4 helped us to identify IP addresses, version number, headers and values and the URL in question. Worksheet 5 helped us practice calculating response time and determining the differences between PSP and Client-Server architecture. In general, these worksheets have been very helpful for me to practice the concepts explained in the text.
