Content Management Systems
A content management system (CMS) is an application that is used to create, maintain and manage digital content.
A modern CMS will present rich web content, including text, images, sound clips and video material, to visitors. The CMS can also protect the content it contains by providing various access levels depending on user privilege levels.
It also allows for users with different security rights to add or edit the content and data it hosts.
There are many CMS systems available; some Open Source and others that employ a variety of licensing models. WordPress is the worlds most popular CMS, with an estimated 70-million sites or blogs running on it.
