Case Project 1-1
case 1 Troubleshooting Network Connectivity on a Small Network
You are asked to visit a small law firm to help troubleshoot some network connectivity problems. The law firm’s network consists of 11 workstations connected by a single 24-port hub. A senior partner describes the problem as “consistent” and explains that every morning there is a five-minute delay to connect to the main server on the network. The senior partner indicates that every user on the network has the same problem. Of course, you brought your protocol analyzer. Where should you tap into this network?

case 5 -Learning the History of the Internet
Open a Web browser on your computer and go to www.isoc.org/internet/history/brief.shtml. Read the chronology of the development of the Internet and then answer the following questions:
- Why were RFCs originally created?
- Briefly compare and contrast how RFCs were used early on with how they are used today.
- What two protocol suites or combination of suites does the Federal Networking Council (FNC) use to define the term “Internet,” specifically describing address space and communication support?
After you are finished, if you want to learn more, read Katie Hafner and Matthew Lyon’s book Where Wizards Stay Up Late: The Origins of the Internet. It’s available through most online booksellers and may be available at your public library.
