URL is the abbreviation for Uniform Resource Locator
and is an address referring to a document on the Internet.
In other words, it is the address of an individual web page
element or web document on the Internet. The syntax of a
URL consists of three elements:
- the protocol, or the communication language,
that the URL uses;
- the domain name, or the exclusive name that
identifies a web site; and
- the path name of the file to be retrieved,
usually an HTML document.
Most newbies mistakenly believe a URL is the same as a domain
name or home page. Every web document and web graphic image
on a web site has a URL.
For example, the URL for a home page is commonly written
as:
http://www.companyname.com/index.htm
- The http:// is the protocol.
- The www.companyname.com is the domain name.
- The index.htm is the path name.
The URL for an About Us page is commonly written as:
http://www.companyname.com/about.htm
- The http:// is the protocol.
- The www.companyname.com is the domain name.
- The about.htm is the path name.
