WWW

WWW stands for the World Wide Web. WWW is the biggest information system on the Internet. These are the documents that are share on the Internet. These are link together. These include the flexibility, portability and user friendly feature. WWW project is first invented by CERN (European laboratory for particle physics). WWW work on some protocols such as FTP and HTTP etc.

WWW is the distributed client/server service, in which client using the browser for the service using the server. However the service over the different location are called site. Each site holds one or more document. These documents are linking together these documents we call that web pages. These links through hypertext

the links that are embedded on a text are called hypertext. For example in a web page, you want to move to the other page of the same site. Then you can click the word that is embedded with the URL and in the response of this you can move to the other page of the same site.

When client request for the site and in the response of this a page of this site is open. The first page that is open on the screen we call that page the home page of the site. the site owner must have menus or pages on the home page that are link the other pages of the sites to the home page. These menus are embedded with the URL.

Client (Browser)

Browser in the windows or any other operating systems works as the client. Each browser mainly consists of three parts: controller, client protocol and interpreters. The controller receives the input from the keyboard or to the mouse. After that when the requested document is in access controller using an interpret display this requested page to the screen. And the client protocol is basically the main protocol HTTP and FTP. The interpreter can be HTML, Java, or JavaScript depending on the type of the document.

Server

The web pages are located in server. Each time client request for the web page the corresponding web page are sending to the client. To make the browser more efficient, the server normally keeps requested web pages to the cache memory because the memory is faster than the disk. The efficiency is increase through the multi-threading and the multiprocessing. In multiprocessing the server can response more than one request at a time.

Uniform Resource Locater

A client needs an address to locate a web page. To facilitate the client for requested document, HTTP uses locat. The Uniform resource locator is specifying the any kind of information on the Internet. Every URL has four things: Protocol, host computer, port and path. Protocols are used to retrieve the document. The host computer is that I which the information is located. URL optionally contains the port number if port number is included. Path is pathname where the information is located.

Web Document   

Web document are of two types: static web pages and the dynamic web pages. Static web pages are the web pages that have only one page that we call home page. On the other hand the dynamic web pages are that web pages that contain hypertext in the home page or the linked web pages. The static pages only contain HTML and the dynamic web pages are the pages contain JavaScript and the other scripting languages.

Websites in these days are the most sharing and the most retrieving on the Internet. Social sites the biggest source for the sharing of data. In social sites every page is spread like the fire in the jungle. People watch and share your site in the social sites.
