1 Web Browsers Introduction to Web Design VICO 361 Brandon Flayler

2 What is the Technology? A web browser or Internet 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.[1] Hyperlinks present in resources enable users to easily navigate their browsers to related resources.

3 What is the Technology? 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 also be used to save information resources to file systems.

4 Who Developed it? When? Why? Tim Berners-Lee developed it in December of It was released in March, Interview with Tim berners-lee: Why did you invent the WWW? “Well, I found it frustrating that in those days, there was different information on different computers, but you had to log on to different computers to get at it. Also, sometimes you had to learn a different program on each computer.” said Tim Berners-Lee. People at CERN came from universities all over all types of computers.

5 History and Milestones ・ WorldWideWeb. Tim Berners-Lee Christmas day, ・ libwww. Berners-Lee and a student at CERN named Jean-Francois Groff 1991 /1992,. ・ Line-mode. Nicola Pellow,1991 ・ Erwise. After a visit from Robert Cailliau, a group of students at Helsinki University of Technology joined together to write a web browser. April, 1992.

6 1990 Web Browser

7 History and Milestones ・ ViolaWWW. Pei Wei, a student at the University of California at Berkeley, released the second browser for Unix, called ViolaWWW, in May, ・ Midas. Summer 1992, Tony Johnson at SLAC developed a third browser for Unix systems. ・ Samba. Robert Cailliau started development of the first web browser for the Macintosh, called Samba. Development was picked up by Nicola Pellow, and the browser was functional by the end of 1992.

8 History and Milestones Mosaic. Marc Andreessen and Eric Bina February, Arena. In 1993, Dave Raggett at Hewlett-Packard Lynx.. Lou Montulli released the web browser Lynx 2.0 in March, Cello. Tom Bruce, cofounder of the Legal Information Institute developed a web browser for that platform called Cello, finished in the summer of 1993.

9 1993 Mosaic Browser

10 History and Milestones Opera. In 1994, the Opera browser was developed by a team of researchers at a telecommunication company called Telenor in Oslo, Norway. Internet in a box. January, 1994, O'Reilly and Associates

11 History and Milestones ・ Navipress. In February, 1994, Navisoft released a browser for the PC and Macintosh called Navipress. ・ Mozilla. In October, 1994, Netscape released the the first beta version of their browser, Mozilla 0.96b, over the Internet. ・ Internet Explorer. On August 23rd, 1995, Microsoft released their Windows 95 operating system, including a Web browser called Internet Explorer.

12 What Groups are Responsible for Managing it? The Information Technology group of the company. Developer of the software

13 What Groups are Responsible for Managing it? Mozilla is a global community dedicated to building free, open source products like Firefox web browser and Thunderbird software. Mozilla Firefox is a free and open source web browser descended from the Mozilla Application Suite and managed by Mozilla Corporation. Functions can be added through extensions, created by third-party developers The Mozilla project was created in 1998 with the release of the Netscape browser suite source code that was intended to harness the creative power of thousands of programmers on the Internet.

14 What Groups are Responsible for Managing it? Instead of just working on Netscape's next browser, people started creating a variety of browsers, development tools and a range of other projects. In ten years the community has shown that commercial companies can benefit by collaborating in open source projects and that great end user products can be produced as open source software. A sustainable organization has been created that uses market mechanisms to support a public benefit mission and this model has been reused by others to create open, transparent and collaborative organizations in a broad range of areas.

15 What Groups are Responsible for Managing it?

16 WebKit is a layout engine designed to allow web browsers to render web pages. It powers Google Chrome and Safari. The WebKit engine provides a set of classes to display web content in windows, and implements browser features such as following links when clicked by the user, managing a back-forward list, and managing a history of pages recently visited.

17 Growth of the Web Browser For years, the Web browser was a technology that seemed frozen in time. While the Web itself exploded with new types of content and virtual communities, the way users accessed that material changed hardly at all from 1997 to 2004.

18 Growth of the Web Browser Of course, new versions of the most popular Web browsers come along regularly. Microsoft released Internet Explorer 9 on March 14; Mozilla upgraded Firefox to version 4 on March 22

19 Growth of the Web Browser Browster, for example, offers a free add- on for Internet Explorer and the Mozilla Foundation's open-source Firefox browser that's a simpler alternative to using the "Back" button.

20 Growth of the Web Browser

21 A plugin for Internet Explorer and Firefox, lets users preview other Web pages without leaving the current one, by moving a cursor over an icon appearing above each link.

22 Growth of the Web Browser companies like Flock are developing entirely new browsers to facilitate now-common social activities, such as blogging, RSS-based news reading, and photo sharing. Not only can you use it on the computer, but it is now integrated into mobile devices, DVD players, and video game counsels.

23 Related and Competing Technologies Apps, social networks

24 Pros and Cons FireFox Pros: Fast, very customizable, uses fewer system resources than most Cons: So many options can be confusing, crash on one tab crashes all, private browsing requires add-in, many other features require add-ins

25 Pros and Cons Google Pros: Fast and simple, stable, private browsing option, enables offline use of Internet apps Cons: No ad blocking, minimal options, skimpy bookmarking, uses a lot of system resources

26 Pros and Cons Opera Pros: Doesn’t bog down older computers, excellent history of searching, synchronize across computers Cons: No ad blocking, not the fastest, no private browsing

27 Creation of Accessibility Limitations and Improvements The browser as operating system, Functionally-limited mobile applications, Web-enhanced devices, Personalization.

28 Pushing the Limits Flock 2.5 Firefox 5 Internet Explorer 9 Web Os Chrome Os

29 Future Technology Worldwide Market Shares Influence of Google Chrome Competition amongst Web Browsers
