Unix Cron is a daemon ('service') that runs in the background and runs the commands specified in the crontab file at the intervals specified within. This allows someone to easily run a program or script every hour, day, week, etc.
The crontab file can be found in two places. Typically, it is located in the /etc directory. Cron also supports multi-user setups, in which case you will also find other 'crontab' files in some distribution-specific location (I believe /var/spool/cron, named after the user that owns the file).
More information on Cron can be found by Googling "cron" or "crontab".
