The architecture of WWW: The World Wide Web (WWW) is a collection of documents and other web resources which are identified by URLs, interlinked by hypertext links, and can be accessed and searched by browsers via the Internet. The World Wide Web is also called the Web and it was invented by Tim Berners-Lee in 1989. A website is a collection of web pages belonging to a particular organization. The pages can be retrieved and viewed by using a browser. 1. Client (Browser): The web browser is a program, which is used to communicate with a web server on the Internet. Each browser consists of three parts: a controller, client protocol, and interpreter. The controller receives input from an input device and uses the programs to access the documents. After accessing the document, the controller uses one of the interpreters to display the document on the screen. 2. Server: A computer that is available for the network resources and provides service to the other computer on request is known as the server. The web pages are stored on the server. The server accepts a TCP connection from a client browser. It gets the name of the file required. The server gets the stored file. Returns the file to the client and releases the top connection. 3. Uniform Resource Locator (URL): The URL is a standard for specifying any kind of information on the Internet. The URL consists of four parts: protocol, host computer, port, and path. The protocol is the client or server program which is used to retrieve the document or file. The protocol can be FTP or HTTP. The host is the name of the computer on which the information is located. The URL can optionally contain the port number and it is separated from the hostname by a colon. The path is the pathname of the file where the file is stored.
