Everyone knows about www. on the internet, what other prefixes are there and what are they for?

Answer 1

2003-12-11: a web site can have any valid domain name. Starting the domain name name of your web site with www. or www2. or www3. is a common convention and nothing more. There is nothing in the HTTP specification that says a web site must start with www. or any other prefix. It is simply a convention that began in the early days of the web and was used to distinguish a company's web server from its FTP server, gopher server, mail server, et cetera. But no such distinction is necessary, because web servers respond on TCP port 80, which is distinct from port 25 (outgoing mail), port 110 (POP mail), port 21 (FTP control), et cetera. A single domain name can host all of these services, and a single physical computer may actually respond to many different domain names.
As a matter of common practice, most webmasters make sure their sites respond to both www.mycompanyname.com and mycompanyname.com, because the former is the first guess many people will make, and the latter is both more convenient to type and easier to fit into an advertising logo. It is rare for a well-run web site to reject either name.

Some web sites use www2., www3., www4., etc. as names for additional web servers that handle some of the traffic for the site. But it's strictly up to the webmaster and the person who handles DNS for the domain. These could just as easily be catnip.example.com, dirtnap.example.com or whatever else.

Answer 2

I use my books from Penn Foster. I do about an hour of this each day. I am also using extra books, like Points of Views: An Anthology of Short Stories Edited by James Moffett and Kenneth R. McElheny. I read a story and do a personal outline of what I feel about the story. Other books I am using are grammar workbooks. I have about 10 different ones I use. I do 1-2 hours of personal writing. I use regular journals from Wal-Mart. I'm Using Algebra The Easy Way along with about 4 other math books that range from Algebra to tech math. I'm not sure if I'm going to do Chemistry, but I do have a text/workbook for it. I'll also be working on learning different writing styles. One books that I am using is called If you're trying to teach kids how to write, you've gotta have this book! By Marjorie Frank. I figured that I'd start with something simple and work my way up. As you can see, I focus more on writing then anything else. My goal is to be able to write a book. I haven't decided on the type of book I want to write, but that's why I'm doing so many different types of workbooks and doing a lot of reading.
