Hi Ahmed,

LMS is a learner mangagement system - an administrative platform that manages access, views, stats etc. for course participants and administrators etc.
There are many LMSs including open source versions such as Moodle and Claroline.

You can customize free versions of the above to run on your own servers (or local host for testing)but you will need to refer to the help/supports available from the respective LMS providers. I suggest you google Moodle and/or Claroline for more information.

Kind regards,

Frank
