The Moodle 'cron' process is a script that runs in the background different tasks at scheduled intervals. In Moodle, these scheduled tasks include sending mail, updating course or activity completions, posting forum messages or other tasks. Cron is a server operating system program, which needs to be told to trigger the Moodle cron scripts.

IMPORTANT: Do not skip setting up the cron process on your server for your Moodle. Your site will not work properly without it

On some Moodle sites it is possible to trigger the Moodle cron script by running yourmoodle/admin/cron.php in the address bar of a web browser.
