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.html
- The http:// is the protocol.
- The www.companyname.com is the domain name.
- The index.html is the path name.
The URL for an About Us page is commonly written as:
http://www.companyname.com/about.html
- The http:// is the protocol.
- The www.companyname.com is the domain name.
- The about.html is the path name.
