Window to Web Browsing
One of the most common problems all Internet users face is the fact that it can be quite difficult to find what you want on the Internet. There is no central “main menu” that users can access to navigate through the Internet. Although there might not be an official menu, there are several resources available – both on-line and off-line – that can make “surfing the net” easier. The Internet is a terrific resource. It contains hundreds of web sites dedicated to thousands of topics. There are some web sites, which are used to search information on the web. This searching on the web, moving from page to page, website to website in search of information is known as web browsing. There is one main software/application which is mainly used for the web browsing, called web browser . There are different types of web browser. Search services on the Internet come in two main flavours: 1) ‘search engine’ that index words or terms in Internet documents; and 2) ‘directories’ that classify Web documents or locations into an arbitrary subject classification scheme or taxonomy. Most search engines take one or more words entered by the user, search the contents of every Web page stored in their databases and display the result. Search engines tend to “index” (record by word) all of the terms on a given Web document. Internet directories are on-line Web sites that place Web page into one or more categories. Web pages are usually listed with a brief description and their URL.Directories operate on a different principle. They require people to view the individual Web site and determine its placement into a subject classification scheme or taxonomy. Once done, certain keywords associated with those sites can be used for searching the directory’s data banks to find Web sites of interest some popular search engineers are:-
• Google- http://www.google.com
• Infoseek- http://guide.infoseek.com
• Alta Vista – http://www.altavista.digital.com
• Lycos – http://www.lycos.com
• Yahoo! – http://www.yahoo.com
A web browser is an interface that helps a computer user gain access to all the content that is on the Internet and the hard disk of the computer. It can view images, text documents, audio and video files, games, etc. More than one web browser can also be installed on a single computer. The user can navigate through files, folders and websites with the help of a browser. When the browser is used for browsing web pages, the pages may contain certain links which can be opened in a new browser. Multiple tabs and windows of the same browser can also be opened.There are four leading web browsers: Explorer, FireFox, Netscape and Safari but there are many others browsers available.
Netscape is one of the original Web browsers. This is what Microsoft designed Internet Explorer to compete against. Netscape and IE comprise the major portion of the browser market. Netscape was introduced in 1994.
Internet Explorer (IE) is a product from software giant Microsoft. This is the most commonly used browser in the universe. This was introduced in 1995 along with Windows 95 launch and it has passed Netscape popularity in 1998.
Safari is a web browser developed by Apple Inc. and included in Mac OS X. It was first released as a public beta in January 2003. Safari has very good support for latest technologies like XHTML, CSS2 etc.
Firefox is a new browser derived from Mozilla. It was released in 2004 and has grown to be the second most popular browser on the Internet.
Opera is smaller and faster than most other browsers, yet it is full- featured. Fast, user-friendly, with keyboard interface, multiple windows, zoom functions, and more. Java and non Java-enabled versions available. Ideal for newcomers to the Internet, school children, handicap and as a front-end for CD-Rom and kiosks.
This web browser was developed by Google. Its beta and commercial versions were released in September 2008 for Microsoft Windows. It has soon become the fourth-most widely used web browser with a market share of 1.23%. The browser versions for Mac OS X are under development.
