Safari

This is one browser that is dedicated to the Mac Operating System. For the general public, Macintoshes have always been computers that you want to own, but not necessarily use for work. However, there are a niche set of users who swear by the Macintosh for their daily tasks.

Safari was a browser that toppled Internet Explorer as the default browser in the Macintosh. It made its debut on June 23, 2003 and was the default browser in the OS X v 10.3 operating system.With the release of Mac OS X v10.4, Safari is the only Web
browser included with the operating system.

Safari uses Apple’s WebKit application framework for rendering Web pages and for running JavaScript. WebKit is comprised of two other frameworks which are WebCore an HTML parser based on KHTML and JavaScriptCore which is based on KJS. The Safari browser is a delight to use. It has a bookmark management scheme, contains the integrated Apple QuickTime multimedia technology (obviously!) and also features tabbed browsing. The Google search engine box is the default search engine for the browser. Other features include software that automatically fill out Web forms and spell check entries into Web page text fields. The latest version of Safari was released on April 29, 2005 and includes a built in RSS and Atom reader. It also includes a private browsing mode (which does not record any information of your Web visit) and Parental Controls. It now also has the ability for saving Web sites completely as Web Archives.

In this section, we have talked about browsers from the past and those available currently. A browser, as mentioned earlier, is the first gateway to the Internet for any user across the planet— irrespective of the OS used. Browser evolution is a constant and consistent process, and newer browsers such as Avant and Deepnet provide more functionality to your browsing without weighing down your computer resources. For now, you should choose the browser that best suits your needs.

Mozilla Firefox is the hottest new browser on the scene and it has taken computers users worldwide by storm. Firefox has made a measurable depression in the market share of the world’s favorite browser and that too in an era when users are taking to computers like a duck to water.

Firefox has quite a history of its own, a very young but interesting history. Firefox began not as Firefox, but as Phoenix, which was made available to the public on September 23, 2002. The first build of the browser which was the 0.1 version was not available as an installer, but as an executable. You needed to click on the executable to start the browser. The Phoenix browser used a large amount of Mozilla source code and the initial release was codenamed “Pescadero”, Spanish for “angler”.


Feature-wise it was extremely primitive, but it still contained some useful features Mozilla Firefox such as a popup blocker, tabbed browsing and an integrated download manager. However, shortcut features such as writing the URL then pressing [Ctrl] + [Enter] to automatically fill in the "www." and “.com” parts of the URL were not available in version 0.1. Phoenix 0.2 was released a few days later on 10 October 2002 and had plenty of more features compared to the previous release.The major change in this version was the tool bar which had undergone a complete change. The side bar made its first appearance in this version.

Other enhancements were implemented including new options to the preferences section. Now users were able to disable Java and edit some tabbed-browsing options. Phoenix 0.2 also introduced the ability to add extensions and themes to the browser. Phoenix version 0.3 was the first release of Mozilla that had an integrated search engine by default in the toolbar. The Mozilla team at the time was concentrating on enhancing the browser and spent most of their time on doing that. Although this release had bug fixes, it was still buggy and unstable.

The next major change came with the release of the Firebird browser. Yes, Mozilla changed the name of the browser from Phoenix to Firebird. This was done to avoid trademark issues with a company called Phoenix Technologies, which makes a browser of its own. After months of brainstorming, the Mozilla team rested on a new name, Firebird. However, the name Firebird had to be changed again later because Firebird was the name of an open source development project that makes a relational database. The general look and feel of the browser was also changed to support the name change. The term “Preferences” turned into “Options”, and the Options window obtained some eye candy. If Firebird 0.6 crashed, the user was now able to submit a message to the developers about this error. The downside to this new browser was the increase in the file size which was an increase by about 6MB.

With all the other bug fixes and releases happening in a span of over a few months, the next change was the re-christening of the browser, again. As mentioned earlier, Firebird was the name of an open source development project that makes a relational database and to avoid the legal issues the Mozilla team settled for the name Firefox after some further brain-storming and research in trademark names. This was mainly because it was closely similar to its previous name, Firebird. With the new name came a new logo: the now famous image of the Flaming Red Fox wrapped around the Globe. Staying true to the logo, the browser spread like wildfire in the coming ays.Firefox 0.8 was the first release to feature a Windows installer. All the previous versions were zip files containing an executable. The theme of the browser remained the same, almost. However, improvements were made to the toolbar features. The default search engine was Google and you also had the option of installing (adding) newersearch engines. The installer was also unique since it gave users the option to install the browser with or without the developer tools.


Soon, Firefox PR 0.10 was released. This was the first build to let users use RSS feeds to read in their bookmarks. Other default search engines such as Google.com, Dictonary.com, Ebay.com, Amazon.com and Yahoo were also added to this version of the browser. Other improvements in this release were a lot of bug fixes and security patches.

Finally, version 1.0 codenamed Phoenix was released in November 9, 2004. It had support for English, French, Chinese, Hebrew, Japanese, Italian and hordes of other languages. As soon was this was made available, downloads of this browser reached a peak and it was downloaded over 1 million times in one day! This speaks oodles about the quality of the browser and the acceptance level of Firefox among users worldwide.

Currently as we write, the latest version of Firefox is 1.0.4. The strongest point of this browser is that it is open source. You can make a million modifications to it, customise it and just keep adding… There are thousands of extensions, themes and add-ons available for Firefox and with each passing day, the number grows. However, this may also be a drawback, as sometimes too many extensions can cause problems as well.

Opera





Opera has always been seen as a browser for users who do not trust IE and want something faster and lighter than Netscape. The Opera browser was started in 1994 as a research project in Norway’s telecom company Telenor. Two engineers from the same company developed the browser Opera for the company’s intranet. On July 14th 1996, Opera’s co-founder Jon von Tetzchner made the first public announcement of Opera on UseNet and Opera came into being for the general public.

Opera was written from a scratch and is not based on the NCSA Mosaic code or interface methodology (as Internet Explorer or Netscape are.) This gives it some unique browsing features such as page zoom, a multi-document interface browsing environment and mouse gestures. It has an extremely small footprint and boasts of an impressive feature set, with great support for HTML, XML, WML, CSS (one of the best implementations), JavaScript, DOM and Java.

Opera Series 1 was not released for the public and was called MultiTorg Opera. This version was used for the Telenor Intranet. The first public version of Opera was the Series 2. The first version is a Norwegian demo version of Opera 2.0 that was included with a PC Magazine and loaded only local Norwegian pages. Series 3 was the first coming in terms of acceptance for Opera worldwide. Version 3.62 was the first version of Opera in terms of features, stability and speed. CSS support was exceptional in this version of Opera.

Opera Beta 4 was released in March 2000 and had support for most of CSS2, all of CSS1, HTML4, XML, and WML. This version was based on a cross-platform core and facilitated the release of Opera for different Operating Systems. A new integrated email client was also included in this version. The first versions of Opera 4 were quite stable and buggy and it was after the release of 4.02 that the browser actually became useful.

The Opera 5 release was noticed by the general public, since this time the browser was not on a 30-day trial period but was adsupported hence people could use the browser long after the 30- day period. New features that were added to this release were mouse-gestures, Instant Messaging features hot list panels and an integrated search. In fact, many users are still using this version of the browser till date.

The long awaited Unicode support was introduced in the Opera 6 release and a new SDI MDI interface was also introduced in the same release. The Opera 6 series was one of the most stable and it was with this release that Opera garnered its own fans and a cult following, but was still miles away from making a dent in either Netscape’s or Internet Explorer’s market shares.

Opera 7 was released in early 2003 and featured a brand new rendering engine called Presto. This engine enhanced and expanded its support for standards and included W3C DOM and the Small Screen Rendering technique for handheld devices. The interface was redone entirely with a custom cross-platform skinning system which significantly reduced resource usage, keyboard shortcuts, mouse gestures, menus and toolbars.


Other new features that were included in this release were features such FastForward,Notes and Slideshow, which made the user experience even more enjoyable. A new news and mail client called M2 was introducedin this version as well as a RSS news reader and an IRC chat client.Opera 8 was released in early 2005 and is currently in version 8.0.1. The major reason for Opera being accepted publicly was not because of its compliance in standards with other browsers, but because of the non-standard browsing enhancements that were absent in its competitors. It is light weight and has its own cult of fans. It has innovative features and is one of the most used browsers on mobile devices.

Currently, Opera has started making inroads in other embedded systems platforms as well. Opera’s market share is starting to make a bit of a dent with users sticking to this alternative browser rather than using Internet Explorer or Netscape. Plus, many of Opera’s innovative features are finding their way into other browsers as well. One of them is FireFox, the browser that we will be talking about next.

Netscape




Netscape has quite some history behind it as a browser. Netscape started out as collaboration between Silicon Graphics founder Jim Clark and Marc Andreessen in mid-1994 to form Mosaic Communications. Mosaic Communications later went on to be renamed Netscape Communications. Andreessen had been a leader in University of Illinois in a software project called Mosaic.

With the advent of the Internet, both Jim and Marc saw the oncoming wave of the Internet, and understood that browsers would be the primary tool to access it, thus making Web-browsing software a huge potentia money-spinner. Within a brief half-year period, many of the original people from the NCSA Mosaic project were working for Netscape, and Netscape was released to the public in December 1994.

Netscape became a big success within months of its release. And some of the contributing factors to its success were the pace. with which software releases took place. New innovations and improvements were constantly being made to the browser and that made it “the” browser to browse the Internet with. Newer HTML capabilities were added with every release to Netscape and in most cases, these enhancements and improvements were much, much better than any other browser could provide at that time. By the summer of 1995, it was a good bet that if you were browsing the Internet, you were doing so with a Netscape browser—by some accounts Netscape had over 80 per cent market share, and Netscape’s browser helped cement their own dominance.

Enter Windows 95 and Internet Explorer, and Netscape met with their first worthy competitor. Microsoft made Operating Systems for a living, and browsers were a spin-off from the OS. For sometime though, Internet Explorer played second fiddle to Netscape and was always playing catch up. There were two advantages that Netscape could not deny that Microsoft had. First that Microsoft was way above Netscape in terms of market penetration, and secondly, Internet Explorer was free while Netscape was not. Netscape wanted to counter this situation in a manner that would impress its clients and in March 1996 launched Netscape 2.

With the launch of Netscape 2 a bevy of must-have breakthrough features (frames, Java, Javascript and Plug-ins) which helped distance it from the pack. To counter the “free” Internet Explorer browser issue, Netscape gave it away for free to carefully selected target audiences, such as students and teachers which helped immeasurably to spread the word and to ensure Netscape’s dominance.

Netscape 3 rolled out in August 96 at almost the same time as Internet Explorer 3.0 and this flared off a war amongst the two mammoths. Although, Netscape was still the dominant one in the browser market, Internet Explorer by then started making their first dents in the browser market and eating into the Netscape pie. One of the improvements that Netscape 3 browser boasted off was “mouseover” which means showing one image when a link is highlighted and a different one when it is not.

At the time,Netscape 3 was considered the benchmark for all other browser and if you wanted to be in the browser market, you would be better off supporting all features that Netscape 3 supported. June 1997 saw the release of Netscape 4 while IE 4 was released in October 1994 and things started to go wrong for Netscape. Both browsers used DHTML (the changing of CSS by means of JavaScript), but had their own implementations and did not pay attention to how the other browser worked.



Suddenly Web sites that used DHTML (or CSS with JavaScript) could be displayed in Netscape and not in IE and vice versa. But Microsoft acting mostly on hindsight went back to the drawing board and wrote the code right from the scratch for IE 4 in the process doing away with the legacy code.

On the other hand, Netscape tried to add the new features on top of Netscape 3’s code engine, a decision that was to have grave consequences. Another factor was that Microsoft’s DHTML implementation was user friendly and attracted both Web designers and developers alike who could write or design programs without having to refer to textbooks. Netscape’s implementation of DHTML though remained in the realm of elite programmers who had code for lunch, dinner and sex.

The Internet in 1997 was looking up with mass sales of computers and new users wanting to hook up to the Internet. They did not want to know what software to download, what software to use as a browser; all they wanted was the Internet “installed” in the computer, for them to click on. As mentioned earlier, Microsoft was in the business of making OSes and Windows was by far the only OS that most non-geek users were happy with. With Internet Explorer being freely available along with the OS, Netscape suffered a major setback in their browser business.

These surges of new users were unburdened with the history of the WWW and along with that the existence of Netscape as a browser, and as a result Netscape came crashing down from the once dominating Internet browser market. As a last ditch effort, Netscape did away with the shareware tag and made Netscape a completely free browser killing their main source of income. However, this solution did not turn out to be Netscape’s saviour. The newer code of Netscape 4 incorporated in the Netscape 3 core started showing bugs and extremely odd ones at that.

Netscape was going down, and fast! Finally, Netscape announced that it was going open source. This was the re-birth of Mozilla as an open source project, but the deliverables were still about 4 years away, making the wait too long for most.

Currently, Netscape has been sidelined by the barrage of new browsers such as Firefox and Opera. Features such as tabbed browsing, which was the mainstay of Netscape, has found new homes in these other browsers. The current version of Netscape is 8.0.2 and is based on the Mozilla Firefox core. For now, Netscape is dependent on the Mozilla Project and the real work actually happens there rather than at Netscape. More about this when we talk about Mozilla!

Internet Explorer arrived at a time when Netscape was the masterof the game. Internet Explorer 1.0 debuted with the second versionof Microsoft Windows 95 that was called, simply enough, “Windows95 with Internet Explorer.” When Windows 95 first made its appearancein July 1995 it included inbuilt support for dial-up networkingand TCP/IP (Transmission Control Protocol/Internet Protocol) plusother key technologies for connecting to the Internet. However, itstill depended on third party browsers, which at that time meantNetscape.

With growing acceptance of the Internet, Microsoft suddenlyrealised the potential of bundling in its own browser and thusInternet Explorer (IE) was born. Internet Explorer technology wasoriginally shipped as the Internet Jumpstart Kit in Microsoft Plus!For Windows 95. Internet Explorer replaced the need for cumbersome,manual installation steps required by many of the existingshareware browsers.Internet Explorer 2.0 arrived in November 1995 and was the first cross platform browser released by Microsoft and worked on both Macintosh and 32-bit Windows. Internet Explorer 2.0 technology introduced Secure Socket Layer (SSL) protocol as well as support for HTTP cookies, Virtual Reality Modeling Language VRML), and Internet newsgroups.

The next big Microsoft browser release was Internet Explorer3.0 in August 1996, which had a completely rebuilt core and consideredone of the best browsers of the time. This browser wasdesigned for Windows 95 and included features that users immediatelytook to such as Internet Mail and News 1.0 and WindowsAddress Book. Later, Microsoft NetMeeting and Windows MediaPlayer were also released. Internet Explorer could now display GIF and JPG files, play MIDI sound files and streaming audio fileswithout the assistance of other applications. For Web programmers,though it was a different story altogether, since IE3allowed for a choice of scripting languages and also CascadingStyle Sheets (CSS).


Moving onwards, Internet Explorer 4 made its debut in 1997and was designed for Windows 95, Windows 98, and Windows NT.Another major add-on to the release of IE4 was Outlook Express,which would be installed in the default installation and was anupgrade from the previous Internet Mail and News application.This was the first offering from Microsoft to compete withNetscape Communicator in terms of a mail client being installedwith a browser.

This was also a major release for Web programmers since theintroduction of DHTML as a scripting language in IE4, Web pages could be designed more dynamically. Users could now expandmenus with a click or drag images and objects around on a Webpage. The Web started to look more like the applications andgames that people were accustomed to and less like a static seriesof pages.In September 1998, Internet Explorer 5 was released. DHTMLfunctionality was improved with more features and with emerging Web commerce ideas.


Internet Explorer 6 was first released in 2001 with therelease of Windows XP operating system. Later on, IE 6was released for other Windows flavours. One of the major improvements in IE6 was the implementation of privacy andsecurity functionality of the browser. Since privacy andsecurity had become customer priorities, Microsoft implementedtools that support Platform for Privacy Preferences (P3P), atechnology under development by the World Wide WebConsortium (W3C).


Internet Explorer has also been available for the Macintosh for a long time. Although Netscape Navigator was the browser bundled with the Mac OS for a long time, it stopped in 1997 when Internet Explorer became the default browser for the Mac. But with the release of Safari browser for the Mac OS, development ofIE for the Mac was stopped.

Today, for any Windows user logging on to the Internet for the first time, the blue “e” icon sitting on the desktop is the gateway to the Internet with the default installation of Windows. To useany other browser, you will need to download or source it fromsomewhere and then install it. The little “e” on the other hand isubiquitous, and all you need to do is double-click.
So where do we go from here?

IE 7 which was scheduled for release along with Longhorn willnow be released prematurely. Newer browsers such as Firefox(which we will be talking about soon) will be present, but let’s
face facts, Internet Explorer is here to stay, never mind the antitrustawsuits.

Tim Berners-Lee invented the World Wide Web or WWW as we know it today in 1989, deploying a working system by 1990. Berners-Lee was the first to invent the browser, and it was simplycalled WorldWideWeb since it was the only way to see the Web. Tim later rechristened this browser ‘Nexus’, to distinguish between the program and the abstract information space “www”which was typed in the Uniform Resource Locator (URL).

WorldWideWeb was written in Objective-C and it would let usersbrowse “http:”, “news:”, “ftp:” and local “file:” spaces.Tim wrote the program for this browser on a NeXT computer.The browser was the best at the time, since it was the only one. If you look at the browser closely, you will see that buttons and features in the browser look similar in Internet Explorer. Here’s a
brief low- down on the functionality of the browser.


The WorldWideWeb (Nexus) BrowserThe menu bar looked like a primitive version of the WindowS Desktop, and clicking on it would provide a list of options similar to the Windows of today. The Navigate menu had things such as “Back”, “Next” and “Previous”, and the last two were useful when you followed a link from a list of links—they meant “go back a step and then take the next link from the same page.”

The “Link” menu had options such as “Mark all” which would remember the URL of the current page where you were. “Markselection” would make a link target for the selected text, give it an ID, and remember the URL of that fragment. “Link to Marked”would make a link from the current selection to whatever URL you had last marked. So making a link involved browsing to somewhere interesting, hitting [Command] + [M], going to the document you were writing and selecting some text, and then hitting[Command] + [L]. “Link to new” would create a new window and prompt for a URL, and then make a link from the selection to thenew document.You never saw the URLs—you could of coursealways find documents by following the link to them.

Using the “Style” menu, you could load a style sheet to definehow you wanted your documents (Web pages) rendered. You could also set the paragraph style to an HTML element’s style such as heading1, heading 2, list element, etc., and then this implied anHTML structure in which the document was written back.

At that time, the “X” close box was unique to NeXT, and according to Tim, Windows copied it. The broken X in the “Tim’s homepage” window means that the document was in the process of being edited and was unsaved.

BROWSERS



Whenever we use the terms ‘logging on to the Internet’, ‘browsing’, or ‘surfing the Internet’, we generally mean using the system’s browser. The word “browser” has had a circumstantial coining since the Internet as a whole is a collection of Web pages, and when we surf the Internet we actually browse a variety of Web pages—hence the word browser. In this section, we will talk about the most popular browsers today.

evolution of internet-right now

Right now, the Internet is growing and at an amazing rate. This rate could perhaps be second only to the burgeoning population of third world countries. Internet use across the planet has grown at a whopping 146 per cent since 2000 and is continuously moving upwards.

The main reason for this is that the Internet has now become an accepted part of the mainstream urban life. The Internet is used for almost everything imaginable from recreation and entertainment to learning about rocket science. However, for every good thing, a million bad ones hit you. The same has happened with the Internet. The Internet is a huge resource for everything under the sun; however, not all the data available is harnessed in the right way or in the right direction.

There is an information overload and within a small time, you can turn from a learner to a researcher. Another factor is that all data that is available on the Internet is not true and should not be accepted at face value, which users normally do. This has been happening since the time Internet came into existence. With more and more users getting online everyday, it has become difficult for searching and sifting through data. Not all results provided by search engines are the one you are looking for. Depending on the search engine used, results provided could be based on which advertiser pays the most. For the statistician in you, here are a few to gulp.

Research to find out the number of Web sites visited by users residing in the US showed that the total number of users in a month was 164,961 out of which, Yahoo!, Time Warner and MSN were the most-visited domains. The Entertainment category comprised a total of 128,863 users whose most visited Web sites were Viacom Online, AOL Entertainment, Yahoo! Music and Windows Media in that order. And these figures are just for a month for users surfing the internet in the US! If we start collating data from other countries, we will definitely achieve a mind-boggling figure. So where do we go from here?

In the 1980s there was a widespread development and use of LAN’s, PC’s and workstations. This allowed the Internet to flourish. By 1985, the Internet was refined and well-established as a technology and although it was still limited, mostly to researchers and developers, regular computer users started using it for daily activities. Electronic mail or e-mail was the most used application and its interconnection between different mail systems was demonstrating the utility of broad based electronic communications between people.


Until this time, networking protocols were still being developed. However, the major protocol that was polished at the time was TCP/IP. In fact, by 1990, the ARPANET was decommissioned and TCP/IP had displaced most other Wide Area Networking (WAN) protocols and was fast becoming the accepted protocol for internetworking.

After a while, the World Wide Web came into existence. A consortium called the World Wide Web Consortium (W3C) was also formed which was led initially by Tim Berners-Lee (the inventor of the WWW) and Al Vezza. The W3C is the consortium that has taken on the responsibility for evolving the various protocols and standards associated with the web. This happened in 1992.

Soon after this, the commercialisation of the Internet started taking place. There was a marked increase in the number of communities across the Internet. Bulletin Board Services and Usenet groups were now home to more computer users than ever before. With the advent of such information, corporations and businesses also started looking at the Internet in terms of business viability.

In 1994, Pizza Hut started offering pizza ordering on its Web page while First Virtual, the first ‘cyberbank’, launched its online presence. By this time, there were more than 3,864,000 hosts on the Internet. Since then, the Net has grown rapidly and the process continues to this day.
