It is the application of discrete logic gates (circuitry) without using clocks or counters to sequence a specified task. ususally unversal gates are implemented.
Combinational logic (also called combinatorial logic) is a type of logic circuit whose output is a function of the present input only. This is in contrast to sequential logic, in which the output depends not only on the present input but also on the history of the input. In other words, sequential logic has memory while combinational logic logic does not.
Yes,
It(combinational) depends with present input only. Where as in sequential,the circuit depends with present input and past output(memoried output).
