Web Browser Tips
A Web browser is a software application that enables a user todisplay and interact with text, images, and other information typicallylocated on a web page at a website on the World Wide Web or a local areanetwork. Text and images on a web page can contain hyperlinks to otherweb pages at the same or different websites. Web browsers allow a userto quickly and easily access information provided on many web pages atmany websites by traversing these links.
Popular browsers available for personal computers include MozillaFirefox, Microsoft Internet Explorer, Opera, Netscape,and Apple Safari. Web browsers are the most commonly used typeof HTTP user agent. Although browsers are typically used to access theWorld Wide Web, they can also be used to access information provided byweb servers in private networks or content in file systems.

Web browsers communicate with web servers primarily using HTTP(hypertext transfer protocol) to fetch webpages. HTTP allows web browsersto submit information to web servers as well as fetch web pages from them.The most commonly used HTTP is HTTP/1.1, which is fully defined in RFC2616. HTTP/1.1 has its own required standards that Internet Explorer doesnot fully support, but most other current-generation web browsers do.
Pages are located by means of a URL (uniform resource locator), whichis treated as an address, beginning with http: for HTTP access. Many browsersalso support a variety of other URL types and their corresponding protocols,such as ftp: for FTP (file transfer protocol), rtsp: for RTSP (real-timestreaming protocol), and https: for HTTPS (an SSL encrypted version ofHTTP).
The file format for a web page is usually HTML (hyper-text markup language)and is identified in the HTTP protocol using a MIME content type. Mostbrowsers natively support a variety of formats in addition to HTML, suchas the JPEG, PNG and GIF image formats, and can be extended to supportmore through the use of plugins. The combination of HTTP content typeand URL protocol specification allows web page designers to embed images,animations, video, sound, and streaming media into a web page, or to makethem accessible through the web page.
Early web browsers supported only a very simple version of HTML. Therapid development of proprietary web browsers led to the development ofnon-standard dialects of HTML, leading to problems with Web interoperability.Modern web browsers support standards-based HTML and XHTML, which shoulddisplay in the same way across all browsers. Internet Explorer does notfully support HTML 4.01 and XHTML 1.x yet. Currently many sites are designedusing WYSIWYG HTML generation programs such as Macromedia Dreamweaveror Microsoft Frontpage. These often generate non-standard HTML by default,hindering the work of the W3C in developing standards, specifically withXHTML and CSS (cascading style sheets, used for page layout).
Some of the more popular browsers include additional components to supportUsenet news, IRC (Internet relay chat), and e-mail. Protocols supportedmay include NNTP (network news transfer protocol), SMTP (simple mail transferprotocol), IMAP (Internet message access protocol), and POP (post officeprotocol). These browsers are often referred to as Internet suites orapplication suites rather than merely web browsers.
Browser Comparasion
Microsoft's tight grip on the Internet browser market is rapidlyslipping. Internet Explorer use has fallen below 90 percent of the marketin the United States and as low as 69 percent in Germany. What's makingpeople leave IE are the numerous security concerns and the simple factthat functionality (tabbed browsing and a built-in Really Simple Syndication[RSS] feed reader) promised in version 7 of Internet Explorer, expectedto be in beta late this summer, is already available in other browsers.Add to that Microsoft's controversial decision to offer the next versionof Internet Explorer only to people running Windows XP SP2.
Rapidly forcing IE from desktop dominance is Mozilla Firefox.This open-source browser receives our highest rating, in part becauseit includes tabbed browsing and RSS feeds, is very easy to use, and iswell supported with a variety of third-party plug-ins. Firefox's popularityhas recently helped unearth a few vulnerabilities, but the speed and forthrightnesswith which Mozilla has patched its browser is very impressive.
Netscape 8 takes the best of both worlds. It runs both IE andMozilla's engines, should sites you want to visit render properly onlywith IE. Netscape 8 also includes tabbed browsing, and it's easy to use.Another browser actually built upon the Microsoft IE engine is DeepnetExplorer. Think of Deepnet Explorer as Internet Explorer the way you'dlike it to be--today.
Two unique browsers are also available. One is Apple Safari RSS,designed to run on the Mac OS X operating system. Bundled withMac Tiger OS (and available for download for previous Mac OS X users),Safari offers tabbed browsing, an RSS reader, and increased speed forMac users fed up with IE for Mac.
Finally, there's Opera, which uses neither the IE nor the Mozillaengine. There are many cool new features introduced in Opera 8, such asits ability to stretch and resize Web pages to fit your desktop needswithout sacrificing content. Unfortunately, Opera comes with a catch:in order to get all of the advanced features, you'll need to pay $40 orput up with an endless stream of banner advertising on the free version.This makes the value proposition for Opera 8 questionable at best.
