Short for "cron table". Can refer to the system crontab or Magento's own cronjob management
crontab is the Unix command to manage cron tables.
Magento uses the term crontab for its own cronjob management. Example crontab configuration from Mage_Backup:
<crontab>
<jobs>
<system_backup>
<run>
<model>backup/observer::scheduledBackup</model>
</run>
</system_backup>
</jobs>
</crontab>
You can also use the more general tag cron
