You’ve probably heard the familiar “h” “t” “t” “p” “colon”
“slash” “slash” a zillion times, but what does it mean? First, of
all, the Web addresses you type into the browser are called
URLs or Uniform Resource Locators.
If it were up to us we would have called them “Web addresses,”
but no one asked, so we’re stuck with Uniform Resource
Locators. Here’s how to decipher a URL:

The first part of
the URL tells you
the protocol that
needs to be used
to retrieve the
resource.
The second part is
the Web site name.
At this point you
know all about that.
And the third part is
the absolute path to
the resource from the
root folder.
To locate anything on the Web, as long as you know the server
that hosts it, and an absolute path to the resource, you can create
a URL and most likely get a Web browser to retrieve it for you
using some protocol – usually HTTP.

A Uniform Resource
Locator (URL) is a
global address that
can be used to locate
anything on the Web,
including HTML
pages, audio, video,
and many other forms
of Web content.
In addition to
specifying the location
of the resource, a
URL also names the
protocol that you can
use to retrieve that
resource.
