• A web browser is a software application for retrieving,
presenting, and traversing information resources on
the World Wide Web. An information resource is
identified by a Uniform Resource Identifier (URI) and
may be a web page, image, video, or other piece of
content. Hyperlinks present in resources enable users
to easily navigate their browsers to related resources.
• Although browsers are primarily intended to access
the World Wide Web, they can also be used to access
information provided by Web servers in private
networks or files in file systems. Some browsers can be
also used to save information resources to file systems.
• There are different web browsers that are
available and in use today and they all come
with a variety of features. Some of the available
web browsers include Amaya, AOL
Kiosk, Dillo, Elinks, Epiphany, Flock, Galeon, iCab
, Internet Explorer, Internet Explorer for Mac, K-
Meleon, KioWare, Konqueror, Links, Lynx, Maxth
on, Mosaic, Mozilla, Mozilla
Firefox, Netscape, OmniWeb, SeaMonkey, Safari
, Opera and Off By One. Most of these web
browsers are free, but there are five of them
that do have a purchase price.
• WorldWideWeb was the first web browser. When it was
written, WorldWideWeb was the only way to view the Web.
• The source code was released into the public domain in
1993. Some of the code still resides on Tim Berners-Lee's
NeXTcube in the CERN museum and has not been
recovered due to the computer's status as a historical
• It was capable of displaying basic style sheets, downloading
and opening any file type supported by the NeXT
system, browsing newsgroups, and spellchecking. At
first, images were displayed in separate windows, until
NeXTSTEP's Text class supported Image objects.
• Mozilla Firefox is a free and open source web
browser descended from the Mozilla Application
Suite and managed by Mozilla Corporation. As of
June 2010. Firefox was the second most widely
used browser, with 23.81% of worldwide usage
share of web browsers.
• To display web pages, Firefox uses the Gecko
layout engine, which implements most current
web standards in addition to several features
which are intended to anticipate likely additions
to the standards.
• Mosaic is the web browser credited with popularizing the World
Wide Web. Its clean, easily understood user interface, reliability,
Windows port & simple installation all contributed to making it
the application that opened up the Web to the general public.
Mosaic was also the first browser to display images inline with
text instead of displaying images in a separate window.
• Mosaic was developed at the National Center for
Supercomputing Applications(NCSA) at the University of Illinois
Urbana-Champaign beginning in late 1992. NCSA released the
browser in 1993, and officially discontinued development and
support on January 7, 1997. However, it can still be downloaded
• Netscape Navigator and Netscape are the names for
the proprietary web browser popular in the 1990s.
• It was the flagship product of the Netscape
Communications Corporation and the dominant web
browser in terms of usage share, although by 2002 its
usage had almost disappeared.
• This was partly due to the increased usage of
Microsoft's Internet Explorer web browser software
and other web browsers, and partly because the
Netscape Corporation (later purchased by AOL) did not
sustain Netscape Navigator's technical innovation after
the late 1990s.
Windows Internet Explorer
• Windows Internet Explorer (formerly Microsoft Internet
Explorer), is a series of graphical web browsers developed by
Microsoft and included as part of the Microsoft Windows

most widely used web browser since 1999, attaining a peak
of about 95% usage share during 2002 and 2003 with IE5 and
• That percentage share has since declined in the face of
renewed competition from other web browsers. Its usage
share now sits at approximately 50% to 60% and is slowly
trending downward. Microsoft spent over $100 million a
year on IE in the late 1990s, with over 1,000 people working
on it by 1999.
• Opera is a web browser and Internet suite developed by Opera
Software. The browser handles common Internet-related tasks such
as displaying web sites, sending and receiving e-mail messages,

built-in phishing and malware protection, strong encryption when
browsing secure websites, and the ability to easily delete private

including Microsoft Windows, Mac OS X, Linux, and FreeBSD. The
Desktop Team recently dropped support for Solaris.
