That can have different answers. There are 6 levels on the Fujita Scale ranging from F0 to F5 (EF0 to EF5 on the Enhanced Fujita scale). But these are only levels of intensity and do not divide tornadoes into distinct types.
Type 1: also known as supercell tornadoes. These tornadoes, which form from the mesocyclone of a supercell, are the most common type and are generally the strongest. They are the only ones that can reach EF4 an EF5 intensity. On occasion these tornadoes can become very large.
Type 2: also known as landspouts or waterspouts* depending on where they occur. These tornadoes most often form from developing thunderstorms. They are weaker on average than supercell tornadoes but on rare occasions can be as as strong as EF3. When they occur as landspouts they often produce a characteristic dust tube.
Other tornado-like circulations such as dust devils, fire whirls and gustnadoes are not considered tornadoes.
*Type 1 tornadoes can occur as waterspouts as well, though not as often as type 2. They are called tornadic waterspouts. Waterspouts are usually not officially counted as tornadoes unless they hit land.
