2.4.1 A period is divided into multiple jams, which are races between the two teams to score points. There is no limit to the number of jams allowed in each period.

Down to basics. Today's rule explains what jams are. As the rules put it, jams are races where the Jammers are trying to score points and the Blockers are defending against being scored on. If ever you are confused as to how to explain derby to someone, you say that it is simply a series of short races to score points. This rule states that there is no limit to the number of jams allowed in a period. I've previously thought that mathematically there had to be a limit, considering the 30 second lineup time between jams. However, if Official Timeouts are continually called as soon as the jam begins, in theory there could be dozens, hundreds, or more jams in a period. Of course, that is theoretical, and would require some serious jackassery by the refs, and I doubt such a ref crew exists. However, the rule does state that there no limit to the number of jams that may happen in a period. The period is only limited by the period clock.
