Prison inmates have been tried and convicted of crimes, where as those in jail may be awaiting trial. A prison is under the jurisdiction of either federal or state, while a jail holds people accused under federal, state, county and/or city laws.

It doesn't really matter unless you plan on studing/practising law.
