Okay, so we've learned how every person on the Internet has a unique email address. Each "page" on the Web also has a unique address. These addresses are called URL's, it's an acronym for Universal Resource Locator. They are a little more complicated so stay with me here.

Every URL has three parts that are separated by forward slashes ("/"). Those three parts are:

Access Method

Web browsers have the ability to access many types of information. As such a URL needs to know what type of information it will be accessing. In most cases a technical acronym is used. Here is a short list;
http:

This is an acronym for hypertext transfer protocol and it is the basic Web service that provides those nice looking pages.
ftp:

File Transfer Protocol, this method allow for browsing and transfer of program and data files.
gopher:

Gopher is an older less attractive version of the Web.

System name

The system name portion of a URL follows the access method. It is separated by the access method with two forward slashes ("//"). This name uniquely identifies a computer on the Internet.

Resource name

The resource name uniqely identifies a document or file on the system. This is usually a directory name and file name. It follows the system name and is separated by a single forward slash ("/").

When we pull at this together the format lookes like this;

AccessMethod://System.name/ResourceDirectory/ResourceFile

So to find the Web page "/howto/fix_conn.htm" on the system www.Discovery.net the URL would be;

http://www.Discovery.net/howto/fix_conn.htm
