This is the Uniform Resource Locator (URL) of the web page you are looking at right now. A URL can be thought of as the "address" of a web page and is sometimes referred to informally as a "web address."
URLs are used to write links linking one page to another; for an example, see the HTML entry.
A URL is made up of several parts. The first part is the protocol, which tells the web browser what sort of server it will be talking to in order to fetch the URL. In this example, the protocol is http.
The remaining parts vary depending on the protocol, but the vast majority of URLs you will encounter use the http protocol; exceptions include file URLs, which link to local files on your own hard drive, ftp URLs, which work just like http URLs but link to things on FTP servers rather than web servers, and mailto URLs, which can be used to invite a user to write an email message to a particular email address.
The second part of the example URL above is the fully qualified domain name
of the website to connect to. In this case, the fully qualified domain name is
www.boutell.com. This name identifies the web
site containing the page. The term "fully qualified domain name" refers to
a complete website or other computer's name on the Internet. The
term "domain name" usually refers only to the last part of the name,
in this case
boutell.com, which has been registered for that
particular company's exclusive use. For more information about registering
domain names, see the setting up
The third part of the example URL is the path at which this particular
web page is located on the web server. In this case, the path
/newfaq/basic/url.html. Similar to a filename, a path
usually indicates where the web page is located within the web space
of the website; in this case it is located in the
sub-folder of the
newfaq folder, which is located in the
top-level web page directory of our website.
