Interactive Web

• Web has a client/server structural design, where a browser runs on the client such as Microsoft Explorer or Netscape and a Web server like Apache server runs on the server machine.
• However in 1995 W3C published HTML 2.0 which included forms that made it possible to use Web interactively
• In the early days of the Web, there was processing neither on the client nor on the server.
• A user accessed only static documents which are the pages that exist on the Web server and are simply delivered to the Web browser. 
• A Web form, is an HTML page with one or more data entry fields and a mandatory "Submit" button.
