4. http:// stands for HyperText Transfer Protocol.
'Protocol' is a set of rules a browser and a web server
use to communicate with and understand each other.
A network protocol defines rules and conventions for
communication between network devices. Protocols
for computer networking all generally use packet
switching techniques to send and receive messages in
the form of packets.

somewhere on the World Wide Web.

6. The next section, which is cnn in this example, is the
name of the server or web site.
It is flanked by dots, which separate it from other
sections of the web address.

7. The .com here is the domain.
This tells you where the web page is registered, and
often tells you what kind of web site it is.
For instance, .com usually means that you're looking
at a commercial site, or a site that someone has paid
to use. Some other common domain names are .edu
(sites for educational institutions), .org (sites
belonging to organizations), and .gov (sites sponsored
by local, state, or federal governments).

hardware) that responds to requests across a computer
network to provide, or help to provide, a network
service.

9. A browser is a software application designed to help
you access information on the World Wide Web.
At its most basic, a browser will:
1. Allow you to enter the URL of the resource you
wish to retrieve from the internet
3. Send a message to a server requesting that
resource
4. Accept the resource when the server returns it
5. Translate the resource into a correctly laid out,
viewable web page.

text interspersed with formatting instructions of
Hypertext Markup Language (HTML, XHTML).
A webpage may incorporate elements from other
websites with suitable markup anchors.
