Static(memoryless)

Dynamic(memory)

Causal

Noncausal

A system is static (memoryless) if its output at any arbitrary time depends on the input at exactly the same time.

A system which has memory (i.e., it is not memoryless) is a dynamic system.

A system is causal if the output at any time t1 (n1) depends on values of the input at t

In other words, a system is causal if its output is generated during or after the application of input and not before! Causal systems are also called non-anticipatory. A system which is not causal is called noncausal.
