  causal systems are the systems which give the output based on the previous and present inputs. these systems do not have output dependency on the outputs after a specific time interval and this time interval depends on the system requirements.

  In Causal systems the output at a discreet time n1 depends on present inputs(at n1) and past inputs(nn1). This might confuse you but you should realise that some sytems work on stored data and hence at a specific time they know what the future input will be.
