What You Will Learn How does the web work?

How does a client find a random web server? How does a request make its way from a web

browser to a web server and how does the reply makes it back?

How is it that all data transmitted arrives intact and in order?

How insecure is the connection and how secure is a secure connection?

10

What You Will Learn-cont. Why do we get the level of performance

that we do? How do the millions of web requests and

responses that transit the CSU campus network every second share the capacity of the network?

Can one control or even improve the performance of their network connections?

important?” The answer is “Yes!”

Greater Expectations-cont. Student Presentations:

Greater Expectations-cont. Behave and perform in a professional manner
