What Is Web Technologies?
Web Technologies:-
The Web uses the HTTP protocol, only one of the languages spoken over the Internet, to transmit data . Web services, which use HTTP to allow applications to communicate in order to exchange business logic, use the Web to share information. The Web also utilizes browsers, such as Internet Explorer or Netscape, to access Web documents called Web pages that are linked to each other via hyperlinks. Web documents also contain graphics, sounds, text and video.
The Web is just one of the ways that information can he disseminated over the Internet. The Internet, not the Web, is also used for e-mail, which relies on SMTP, Usenet news groups, instant messaging and FTP. So the Web is just a portion of the Internet, albeit a large portion, but the two terms are not synonymous and should not be confused.
Web is a system of Internet servers that support specially formatted documents. The documents are formatted in a script called HTML (HyperText Markup Language) that supports links to other documents, as well as graphics, audio, and video files. This means you can jump from one document to another simply by clicking on hot spots. Not all Internet servers are part of the World Wide Web. There are several applications called Web browsers that make it easy to access the World Wide Web. Two of the most popular being Netscape Navigator and Microsoft's Internet Explorer. In a web page information are presented using the following technologies:
■ HTML
■ Javascript
■ Java Applets
■ Java Server Pages (JSP)
■ Active Server Pages (ASP)
■ Java Servlets
In the above list the browser machine executes the first three whereas the last three run in the server machine. XML is a new technology, which is widely used in data formatting and communication. The web pages also contain objects such as cookies and plug-ins.
