The
Difference Between the Internet
and the World Wide Web
Many people use the terms Internet and World Wide Web
(a.k.a. the Web) interchangeably, but in fact the
two terms are not synonymous.
The Internet and the Web are two
separate but related things.
The Internet is a massive network of networks, a networking
infrastructure. It connects millions of computers together globally, forming a
network in which any computer can communicate with any other computer as long
as they are both connected to the Internet. Information that travels over the
Internet does so via a variety of languages known as protocols.
The World Wide Web, or simply Web, is a way of accessing information
over the medium of the Internet. It is an information-sharing model that is
built on top of the Internet. The Web uses the HTTP protocol, only one of the
languages spoken over the Internet, to transmit data. Web services, which use
HTTP to allow applications to communicate in order to exchange business logic,
use the Web to share information. The Web also utilizes browsers, such as
Internet Explorer or Netscape, to access Web documents called Web pages that
are linked to each other via hyperlinks. Web documents also contain graphics,
sounds, text and video.
The Web is just one of the ways that
information can be disseminated over the Internet. The Internet, not the Web,
is also used for e-mail, which relies on SMTP, Usenet news groups, instant
messaging and FTP. So the Web is just a portion of the Internet, albeit a large
portion, but the two terms are not synonymous and should not be confused.
