Re: Webdesign tools
JOomla is a CMS (Content Mangement System), it allows you to publish, organize and present your data along with various tools, modules, components and plugins to enhance website visitor's experience as well as add functionality to the content.
You will need either LAMP (Linux Apache MySQL and PHP) or WAMP (Windows Apache MySQL and PHP) in order to run Joomla and take advantage of its features. I as well as many other users prefer using it on a linux server.
