It is the same difference as exists in English between perfect and simple verbs. A perfect verb implies past action as well as continuance in the given tense whereas a simple verb only discusses action in a given tense. For example, if I say "I have walked the dog", it means that I walked the dog prior to my current walking of the dog and that the past walking and present walking was continuous. If I say "I walk the dog", it would seem to be something that is generally something that I do, but is not a continuous action.
