CMS stands for Content Management System.
Companies and organizations which have many web pages in their website use content management systems to build and edit their webpages. A Content Management System is essentially a frame work which allows for the sharing of common elements across many different pages. This efficiency helps the web team locate, track and make changes to many pages in the ETSU web site very quickly.
ETSU's website consists of over 600 subsites and about 10,000 individual web pages!
