The Internet and the Web are closely related systems. They are like music and the sound of the music system. The music system plays music yet the two are not synonymous. The Internet (capitalised) is analogous to a music system while the web is synonymous with the music.
The Internet is made up of interconnected computers across the globe. They are connected with copper wires, microwave radios, satellite dishes and fibre optic cables. On these computers are mounted software called servers that hold and manage vast amounts of documents that make up the World Wide Web (WWW). These documents are created using a special technique that makes use of structuring elements called Hypertext Markup Language (HTML). These are used to mark the beginning and ends of such elements as headings, paragraphs, images, tables, lists and on-line forms.
Over the next five months, I shall provide detailed descriptions of how to create HTML-based documents.[Yes, this was done but the descriptions will be part of a small book on web design coming very soon]
Web Technologies
Over the last 15 years or so, several technologies have been created to improve various aspects of web content. These include:

Over the last 15 years or so, several technologies have been created to improve various aspects of web content. These include:
- Hypertext Markup Language (HTML) - used to structure web documents, now in version 5
- Extensible Markup Language (XML) - - used to structure web documents, now in version??
- Cascading Style Sheets (CSS) - used to add style information to web documents, now in version 3
- Javascript - used to create dynamic effects on web documents and implement AJAX (Asynchronous Javascript and XML)
- Scripting engines such as PHP, Java Server Pages and Ruby used to provide intelligence to web pages including publishing live data
- Database Management Systems (DBMS) such as MySQL used to manage data.
