History of world wide web
The World Wide Web ("WWW" or simply the "Web") is a global
information medium which
users can read and write via computers connected to the
Internet. The term is often mistakenly
used as a synonym for the Internet itself, but the Web is a
service that operates over the Internet,
as e-mail does. The history of the Internet dates back
significantly further than that of the World
Wide Web. The hypertext portion of the Web in particular has an
intricate intellectual history;
notable influences and precursors include Vannevar
Bush'sMemex,IBM's Generalized Markup
Language, and Ted Nelson's Project Xanadu. The concept of a
home-based global information
system goes at least as far back as "A Logic Named Joe", a 1946
short story by Murray Leinster,
in which computer terminals, called "logics," were in every
home. Although the computer
system in the story is centralized, the story captures some of
the feeling of the ubiquitous
information explosion driven by the Web.
How the world wide web works?
The network of web servers serves as the backbone of the World
Wide Web. The Hypertext
Transfer Protocol (HTTP) is used to gain access to the web. A
web browser makes a request for
a particular web page to the web server, which in turn responds
with the requested web page and
its contents. It then displays the web page as rendered by HTML
or other web languages used by
the page. Each resource on the web is identified by a globally
unique identifier (URI). Each web
page has a unique address, with the help of which a browser
accesses it. With the help of
the domain name system, a hierarchical naming system for
computers and resources participating
in the Internet, the URL is resolved into an IP address.Presence
of hyperlinks, the worldwide availability of content and universal
readership are some
of the striking features of the World Wide Web. The interlinked
hypertext documents form a web
of information. Hyperlinks present on web pages allow the web
users to choose their paths of
traversal across information on the web. They provide an
efficient cross-referencing system and
create a non-linear form of text. Moreover, they create a
different reading experience. The
information on the web is available 24/7 across the globe. It is
updated in real time and made
accessible to web users around the world. Except for certain
websites requiring user login, all the
other websites are open to everyone. This all-time availability
of information has made the
Internet, a platform for knowledge-sharing. Thanks to the use of
a common HTML format for
rendering web content and a common access method using the HTTP
protocol, the web has
achieved universal readership.
What is the URL? Explain Brieftly.
