A regular frittata is typically an egg dish, similar to an omelet, but instead of cooking the eggs in a pan, the cooked vegetables and eggs are combined in a skillet, and then are transferred to the oven and baked together. Additionally, a frittata is cooked slowly over low heat, and then baked. An omelet is cooked over higher heat on the stove, more quickly. Omelets are typically served hot, but frittatas can be served hot, room temperature or cold. They are also less finicky than omelets and don't need to be "watched" the way an omelet does since there is no risk of overcooking it.
