    Can you be more specific? A logic arrangement that takes data in parallel is a register. A counter indicates events that occur in a sequence. Have you looked at the data sheet for an existing counter (if that is what you want) like a 7490? That is a BCD counter.

    Well he asked us to do jk flip flop connected in series and do another on connected in parallel. That count from 0-9 and I have done the series one but I don't know how to do the parallel one.

    Get the data sheet for a 74162. That is a parallel load capable BCD counter.

    Maybe the question is about parallel (synchronous) clocking vs ripple clocking.

    no, he want us to design parallel and series counter from 0-9 buy using j k flip-flop
    as i said i have done the series counter need help in the parallel counter.
    any ideas

    Here is one definition of a parallel counter.
    Unfortunately, you have to pay EUR 34.00 to read the entire article.

    I don't see why a parallel counter (with this definition) would need flip-flops. It seems to me that it would be combinational logic. There may be other definitions for parallel counter. As beenthere suggested, I believe that parallel-load counters are sometimes called parallel counters.
