There really is no major difference. The Roman Empire was the empire itself, lasting from 27 BCE-476 AD (1453 for the Eastern half, which came to be the Byzantine Empire).

Yes!
The Roman republic was a form of government and the Roman emperor was a man. If you mean the difference between the Roman republic and the Roman empire, there was no difference except in the form of government. Rome was already an empire under the republican form of government. When a single person took over leadership of that government, it became the principate or what is erroneously called the "empire". In both types of government, vast amounts of territory were ruled by a single authority, the senate under the republic and the "emperor" under the principate. Both the republic and the principate met the criteria for an empire.The Roman republic was a form of government and the Roman emperor was a man.
