A cron job is a time-based task that is set to run at a specific interval. For example, a cron job could be set to run every day at midnight in order to update a database or send out nightly emails. Cron jobs are typically used for maintenance tasks that need to be performed regularly.
A crontab is a file that contains instructions for the cron daemon. The cron daemon is a program that runs in the background and executes tasks at specified times.
