The Internet is organized by "domains names"
rented by an individual or company, with an assigned extension. There is reorganization and expansion going on with this issue, but to keep it simple, some of the most common extensions are .com (commercial), .org (organization) .edu (education), .gov (government), .net (internet related services). The differences in these extensions are no longer as meaningful, but when you see an internet address (known as a
URL, which means Uniform Resource Locator and pronounced by spelling out the letters U R L), it may give you some indication of who the sponsor is.
The URL for the Internet101 section of this web site is:
http://www.ker95.com/internet101
- Most of the time it is no longer necessary to type in the http://
- Domain names are not CASE SenSItive (capitalization does not matter), but it
is important to include any dashes (-), underscores (_), forward slashes( /) and any other numbers or characters that may be included in a URL.
- The parts of a domain name that are after a / in the URL ARE CASE SenSItive.
- Domain names can also have an extension that indicates the country where it is
located (uk for United Kingdom, aus for Australia, jp for Japan, etc)
Once a URL has been assigned, it's simply a piece of cyber "real estate". Until a web
page or web site has been constructed there, it will appear as an empty lot (you'll probably receive some sort of "under construction" message). If no one has rented
the URL yet, you may receive a different sort of error message.
