For my first post I read the article "What is a Learning Management System" by Alexandra Toedt.
Basically a Learning Management System or LMS is used to not only present content in a virtual environment like the Internet, but is can be used to also create content. In addition to content creation and presentation an LMS can be used to assess learners as well as used as a communication devise between the learners and the instructor.
There are two types of LMSs that are used. A component approach and an integrated approach. The component approach used several different systems allow the content to be created using a separate system. While the integrated approach has all aspects of the LMS in one system.
