A web page is a document, usually written in Hypertext Markup Language(HTML), which can be accessed on the internet. Web pages may contain text, pictures, movies, sounds, graphics, information and hyperlinks to other web pages and files.

                    Web page is the basic unit of information on the world wide web. It contains text and graphics and other media. Like a book or magazine's page, a web page can be of any length but results are obtained for shorter page length

                     A document created with HTML as a part of a group of hypertext documents or resources available on the world wide web, collectively is known as a website. One can read HTML documents from internet or from local hard disk drive with the help of a software called a web browser. Web browsers read HTML
A Web Page
documents and display them as formatted presentations, with any associated graphics, sound and video on a computer screen. Web pages can contain hypertext links to other places within the same document, to other documents at the same website or to documents at other websites. These also can contain fill-in forms, photos, large clickable images, sounds and videos for downloading.

                       Thus web page is a single document on the world wide web and it is specified by a unique address or URL and it may contain text, hyperlinks and graphics.

                       The web uses the metaphor 'pages', for the organization of information. One page is actually a text file marked up in HTML. It appears in web browser as a page containing images, text, hypertext and graphical links to other points on the same page, other pages, large images, sound or movies. Technically speaking, one page is one computer file that has been marked up with HTML codes. To a person using the web, a page is that unit that can be scrolled through using web browser's scrolling tools. A web page has a top and a bottom, a beginning and an end.

                       Web page is simply collection of electronic information on the web, formatted in HTML and addressed by a single URL.

                       The semantic web provides a common framework. It allows data to be shared and reused by application, enterprise and community boundaries. It is based on the resource description framework, which integrates a variety of applications using XML for syntax and URLs for naming.

                      The semantic web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in co-operation.

HTML(Hyper Text Markup Language):
Hyper text markup language(HTML) is suitable for converting ordinary text into hypertext. It is a set of special codes included to control the layout and appearance of the text. Technically, HTML is not a programming language. It combines instructions within data to form a display program, called browser. HTML has the following features ............

1. HTML is the character based method for describing and expressing the content. the content is pictures, text, sound and video clips.
2. It delivers the contents to multiple platforms.
3. It links document components or documents together to compose compound documents.
4. HTML is a type of code. It embeds simple codes within standard ASCII text documents to provide an integrated, two-dimensional display of text and graphics.
5. Any document created with any word processor and stored in ASCII format can become a web page with the addition of a few HTML codes.

                             Tim Berners Lee developed HTML in early 1990 at CERN(Conseil European De La Recherche Nucleaire), the European  Particle Physics Laboratory in Geneva, Switzerland. HTML is a public domain and not owned by anybody. The WBC(world wide web consortium www.w3.org) is the body, which controls the HTML standards. To develop web pages, we always remember the following three C's of web page design.....

1. Quality content.
2. Artistic composition.
3. Reader convenience.

                           All web pages should be written, viewed and tested before installing the same on a public web server. Any web page on a web server requires ongoing maintenance. Timely information on developed pages should continue to be updated. External hyperlinks should be periodically tested to ensure that these are not obsolete.

                           Web page design is not like desktop publishing where the author has absolute control over the final presentation of the text. Web page display is always dependent on input from both the web page author and the web page reader. Control on the part of the reader is essential because any given browser may be operating on any number of hardware platforms. Large complicated screen displays may be unreadable on the small screen of a laptop computer. For example, a paragraph indentation of 10 characters looks fine in a window that displays 100 characters per line, but it is not so fine in a window that displays only 30 characters per line. Also, browsers wrap text from one line to the next, unless instructed otherwise. Since users can re-size their browser's display window, one user may see the text wrapped after 80 characters, while another sees it wrapped after 60. Users have no control over these things and they may only hope to create a web page that will be easy to read for a majority of users. This makes text formatting in HTML inherently more limited than text formatting with a word processor. It is difficult to know the dimensions of the window prior to displaying it on screen. These uncontrollable factors make to format a challenge to format HTML text. There are also web page construction kits and these can be used to build prefabricated web pages from HTML template. Each template is designed for a particular genre(Example- a personal home page or a small business advertisement). For this, it is required to select a template and add the content.

                           Special HTML editors, interactive assistants and construction bits are all instructional for beginners. The most advanced HTML features are associated with graphics and special effects.

A web page is just a text file. However, it is a text file that contains HTML tags in addition to the text that appears when the page is viewed with a web browser. We can start a web page by writing all of the visible text first and then inserting the HTML tags later. We can edit web page using any text editor or word processor as long as the file is saved as plain ASCII text. A well designed web page normally consists of three parts..........
1. Head
2. Body
2. Graphics

                         The head is reserved for the title of the document as well as some optional data. Every web page should have title which will be displayed in the title bar of a web browser. The title is also important to some search engines which may weigh keywords found in a title more heavily than other keywords. A web page is built with HTML elements, and each element is associated with an HTML tag or pair of tags. For example, the title of a web page is an HTML element, and it is created with a pair of tags that mark the beginning of the title and the end of the title -<title>and</title>:

HTML is a subset of SGML. SGML organized in 1960s at IBM to overcome the problems in moving the documents across the multiple hardware platforms and operating systems. IBMs efforts were called GML(general markup language). Later in 1980, SGML came into existence.
