Web Development using HTML


HTML & The Internet

The Internet (sometimes called “the Net” for short) is a network of computers linked together. It started in 1969 as a US military experiment to share computer resources more efficiently. Later, it was expanded to include colleges and research facilities.

Today, the Net has grown into a massive public broadcast medium. It is an international network of mixed computer technology with more than 600 million users using several different computer languages called protocols. HTML is one the most common and popular protocol.


Where Did HTML Come From?
 In March of 1989, 20 years after the Internet was “born,” Tim Berners-Lee, a computer scientist at the European Laboratory for Particle Physics (CERN) in Geneva, Switzerland published a paper titled Information Management: A Proposal. In it, he suggested a way of managing information by linking related documents and having them all available over a computer network so physicists could share research results with each other. 

History of HTML

At the time, SGML, or Standard Generalized Markup Language, was the standard format for large-scale documents accessed by researchers using computers. As more computers were networked, more documents were put online in SGML format, but SGML was unwieldy and difficult to use.
HTML, or Hypertext Markup Language, combined the wide acceptance of SGML with ease of use. Instead of many commands, HTML used only a small subset, making it easier to learn.

What was truly different about HTML, however, was the concept of links, or references to other documents. Each SGML document was designed to stand alone, but HTML documents are designed to refer to other documents.

 

These references can appear in any web page on any site, and are not limited to references to the same site. This crisscrossing of references makes the World Wide Web a web, and because of its ability to link documents, HTML became the basic language of the Web.

The Web Development Cycle

Each document produced in HTML is considered to be one web page …no matter how long or short it is. An entire group of web pages collected at one location is called a web site (or just “site” for short.)
Web Development Cycle


There are four major stages in the web development cycle:
1. Planning — Writing a web page is simple, however, if you want to create a good site, you will need to put some planning into it. You need to decide what you want to say, organize your thoughts, research what you want it to look like and decide what should be linked to what. This should all be done in the planning stage.

2. Creating — After the web site is planned, you need to write the text and format it with HTML commands. You will also need to gather or create the graphics you will use in your site.

 

3. Testing — After each page is created, you will need to test it on one or more different browsers to make sure it looks and acts like you want it to. You can do the initial testing off-line, on your computer and correct any mistakes before you publish.

 

4. Publishing —Publishing a web site is similar to publishing a book…you make it available to anyone who wants to see it by uploading, or moving your finished page (or pages) from your computer to a web server. A web server is simply a computer whose job it is to send the file to any computer asking to look at it. In creating complicated web pages, it's not unusual for the web page creator to write part of the page, test it, and then write more. The writing and testing stages of the web development cycle usually take the most amount of time.
