Sequential circuits are digital logic circuits where the output depends on both the current inputs and the history of past inputs (i.e., they have memory).
Flip-flops (A) and Counters (C) are examples of sequential circuits. Multiplexers, decoders, and adders are combinational circuits where the output depends only on the current inputs.
