In A Nutshell

The World Wide Web is what we navigate every day,
what you’re reading this page on right now. It dates
to 1991, while the Internet—the underlying network,
the framework on which the Web lies—was created
much earlier.
The Whole Bushel
The mother of all computer networks, the Internet,
grew out of government and university projects in
the early 1970s. The obvious main predecessor of
the Internet, ARPANET, was built by the US
Government’s Advanced Research Projects Agency
and became active in 1969. It was the first computer
network to use packet switching technology—means
of delivering information in small, easily transmitted
“packets” that were relayed along points in the
network (network switches and routers)—which
helped maximize bandwidth efficiency.
Put simply, the Internet is the sum of all other
networks. Your home network, gigantic corporate
networks, the network your cell phone is on—all are
part of the uber-network known as the Internet.
Things like instant messaging and email protocols
were first used in the 1970s, long before the
development of the World Wide Web.

The Web is a sort of graphical user interface for the
Internet. It’s not a physical web of hardware (a
network), but basically the software that runs on it—
or, more accurately, a web of information in the form
of hyperlinks. Hypertext Transfer Protocol (HTTP) is
what enables the Web to run, and it is essentially
just a way to log in to a certain domain (website)
without having to ask permission (say, with a user
name and password).

Though many think of the World Wide Web and the
Internet as being synonymous, the Internet could
(and did) exist without the Web—but the Web
couldn’t exist without the Internet. The first web
page on the first web server was created at
Switzerland’s CERN lab by Tim Berners-Lee on
August 6, 1991.

Thanks for the info. This is a nice research.
