Web Browser Presentation By Alam Zaib Cell.00923005883311

Introduction:

Introduction A web browser is a software application for retrieving, presenting, and passing over 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.

:

Although browsers are initially designed 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.

PowerPoint Presentation:

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 Internet Explorer, Internet Explorer for Mac, Links, Lynx, Mosaic, Mozilla, Mozilla Firefox, Netscape, Omni Web, Safari and Opera. Most of these web browsers are free, but there are some of Browsers do have a purchase price. (The Icons of different Browsers are shown on next Slide)

PowerPoint Presentation:

World Wide Web was the first web browser. When it was written, World Wide Web was the only way to view the Web. The source code was released into the public domain in 1993. It was capable of displaying basic style sheets, downloading and opening any file type supported by the NeXT system, World Wide Web (www)

Netscape Navigator

Netscape Navigator :

Netscape Navigator Netscape Navigator and Netscape are the names for the proprietary web browser popular in the 1990s. It was the main and most popular product of the Netscape Communications Corporation and the commanding 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.

:

Internet Explorer

:

Internet Explorer (formerly Microsoft Internet Explorer ), is a series of graphical web browsers developed by Microsoft and included as part of the Microsoft Windows line of operating systems starting in 1995. It has been the most widely used web browser since 1999, attaining a peak of about 95% usage share during 2002 and 2003 with IE5 and IE6.

:

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.

:

The latest official release, Internet Explorer 8 (IE8), made its premiere performance in March of 2009, and the next major release, Internet Explorer 9, is currently in development. IE9 is expected to offer a faster Java script engine called Chakra.

PowerPoint Presentation:

Although there are many web browsers available and many more are likely to arrive in future, only those which are exciting and user friendly will be able to survive market competition and hold on to a substantial market share .
