Your textbook presents a brief historical summary of the development of the Internet. In the following exercise, you will use online sources to get a more detailed view of several aspects of Internet history.

A helpful tip: if you're using a PC, your mouse probably has (at least) 2 buttons on it. When you click on a link using the left button, the new page opens up, and the page you were looking at before disappears. If you use the right button, though, the new page will open up in its own "window", so you can view the new page and the old page simultaneously. If you're using a Mac, you can do the same thing -- your mouse only has one button, though, so what you have to do is instead of just clicking, hold the button down for a second; a short menu should pop up and you can select "Open in New Window" (or something like that). You may find this helpful in looking for answers and typing them in to the spaces provided.

Another helpful tip: The information you type into the boxes will not be saved if you work on this at different times (and you may find that some sites are very busy at some times, so you may well be forced to work on this in a couple sessions). You have two options for dealing with this: you can work on it all at once, or you can write down your answers somewhere else as you get them, then, when you have all the answers, fill in the boxes and submit the form. PLEASE DO NOT SUBMIT MORE THAN ONCE! I will only grade the FIRST submission I receive from each person.

1. Today, we tend to think of the Internet and the World Wide Web as being synonymous. In fact, the World Wide Web is a relative newcomer to the Internet, and the original ARPAnet network was hardly "world wide".

   Find the answers to the questions below in Hobbe's Internet Timeline:

   1. How many sites were on the original ARPAnet in 1969?
   2. When did research on internetworking begin at ARPA?
   3. When was email invented?
   4. How many years later was the World Wide Web released?

2. One of the factors that contributed to the growth of the Internet was the open quality of the research on internetworking. All of the original Internet research reports, called RFCs, were made publicly available. You can access most of them through the RFC Hypertext Archive.
   1. Who wrote the first RFC?
      When was it written?
      What was it about?
      
      
   2. What is the most recent RFC you can find?
      When was it written?
   3. Look at one page of the index. Can you tell what the different entries in the 'status' column mean? What do you think the column 'obsoleted by' means?
      
      

3. The original ARPAnet project was funded and directed by the Department of Defense. Who pays for everything today? - Look at Economic FAQs About the Internet (What's an FAQ, anyway?)
   
   

4. Often you hear of being connected to the Internet using a T1 line or a T3 line. This table of carrier technologies explains the difference between these types of connections.
   1. How much faster is a T1 (DS1C) connection than a regular telephone connection?
   2. How much faster is a T3 (DS3D) connection than a T1 connection?

5. It has been suggested that cable modems would provide a fast means to access the Internet. See CNET's cable modem article to answer these questions:
   1. What are some of the problems associated with cable access?
      
      
   2. What are alternative high speed access methods?
      
      

6. DSL is one increasingly popular high speed access technology. This article provides a brief summary of DSL technology.
   1. What are some advantages of DSL over cable modems?
      
      
   2. What are some advantages of cable modems over DSL?
      
      

7. You can read about the Internet 2 in the Internet 2 FAQ.
   1. What is Internet 2?
      
      
   2. Who is funding Internet 2?
      
      
   3. How might Internet 2 (eventually) affect your life?
