These scheduled tasks, called "cron jobs," can be used for routine system maintenance like backups, software updates, or running custom scripts to perform tasks like deleting old files or sending out email notifications. End-users, also known as Express Users, are the individuals accessing an application through Express View. In most cases, end-users are the customers using the product.
