What is a Content Management System (CMS) ?
A CMS or a 'Content Management System' is something that is incorporated into your website that allows you to control and manage the content within your web site without any technical knowledge. Using this system you can very easily add, delete images and edit text in your web site on the fly from any web browser without any risk of damaging your design layout.

If you have just a little experience any WYSIWYG text editor such as MS Word then you will be able to manage the content of your own web site very easily without any programming or HTML experience.
