In the most general terms, prehistory differs from history inasmuch as it is that period of time that has occurred before periods in which human ideas and events have been recorded, particularly through writing. In other words, 'history' refers to times or events that have been preserved through records of some kind, while 'prehistory' refers to what came before such records.
The former implies the past and a longer period of time than the latter which implies the future for a short period of time. Here are some examples: "Long before" the time of man, dinosaurs ruled the the world. "Before long" I should be able to start college.
