What that means is that the source code is free to anybody that wants to use Drupal, although you can purchase various forms of customization, including themes and modules to offer specific effects and website components. Drupal is written in PHP and works with a variety of operating systems, including Windows, Linux, MAC and others, and a database system such as MySQL can be used for data storage - in fact a database of some form is essential.



Most of the content in Drupal is made up of what are referred to as ‘nodes'. A node is intrinsically a piece of information, and they can come in a variety of content types. Among the predefined Drupal content types are ‘page' and ‘story', although you can also define your own. There is virtually no limit to the type of website you can develop using Drupal, but it can be heavy on use of resources.

For that reason, you are advised to use a Virtual private server (VPS) or a dedicated server if you intend using Drupal to develop a large website such as a community or social networking site. If you are simply developing a small website for yourself, then you should manage with shared hosting, but otherwise you are best to get a dedicated hosting account.

Although learning Drupal is not difficult, you should learn the right way. By far the best way is to have private tuition, but that can be far too pricy for most people. You can also just play about with it, and pick it up as you go. However, if you are serious about using a Drupal content management system, then a Drupal video course is likely the best solution.

Drupal core is the standard installation of Drupal that contains a taxonomy system that enables content to be tagged with keywords, so that it is easily accessed. It includes a number of modules that enables the functionality of the system to be customized. Among the standard modules in the core download are search functions, a multi-level menu system, access statistics and logging, comments, polls and forums, RSS feed and aggregator and many more.

There are also several core Drupal themes that allow the look and feel of the sites to be customized, and also supports a large number of languages.

If all this sounds complex, it is not as difficult to learn as you might think. A Drupal video tutorial is probably the best way of learning to use Drupal, since you can watch and copy, and replay any part that needs special attention. Using the Drupal open source CMS enables you to put your ideas for unique websites into practice, and also to immeasurably improve the functionality of the blogs, forums and social websites that you will learn to design.
