    I have this question I have to do for school, now we never learned hex but most of the people on the course are fairly smart when it comes to these things and I wont get a chance to talk to them until the day this question is due.

    Ill upload a picture of the question here.

    I'm not asking for an answer here, but I'm just wondering if someone can point me in the right direction of what to study as Im quite confused about the question.

    I can see why you would be lost. I have been programming for 30 years or more. While I have not done much machine code programming for many years but I did it for the first few years of programming. And maybe because it is late but I am not sure I understand.

    I think I have an idea but it could not be that simple. Basically the program is writing a number to the display which as at an address. Hope that gets you started.

    Why didn't you post the text? Afraid the instructor would find it? ;)

    You can study from the below chips, it will give you the conception about how the computer working, and how the digital world working, I can say that it will also affect your life.

    If you have any question about these chips, then you just post it.

    74LS74,Dual D-type Positive Edge-triggered Flip-Flops(With Preset and Clear).

    74LS374,Octal D-type Edge-triggered Flip-Flips(with three-state outputs)
    This is expenden from 74LS74.

    74LS89, 64-Bit Random Access Memory(Open Collector).


    74LS244,Octal Buffers/Line Drivers/Line Receivers(non inverted three-state outputs)
    Similar functions with 74LS125, but expended more.

    74LS138,74LS139, Decoder/Demultiplexer.

    74LS181,4-Bit Arithmetic Logic Unit.

    I've got to second spinnaker - the information in the question is practically indecipherable. My best guess matches spinnaker's, too.

    I'mm guessing that the original question is in some language other than english and that you have given us your translation of it. If so, a lot is being lost, or at least obscurred, in translation. That's not a criticism, your english is much, much better than my ability to work in your language. But if this doesn't appear to help you, you might find someone that has a better command of english to take a shot at it.

    Hey thank you for all the replies, Ill answer some questions firstly yes that is why I posted it in a picture form, haha, but it should'nt matter this question is not part of our syllabus so I don't know why I'm being asked it. I cannot make sense of this either all I can say to maybe shed more light on this is the answer should be fairly straight forward as this is a first year in a four year course. Could it have to do with the Address, Control and data buses sending data? I literally have no idea but the responses are greatly appreciated. Also the questions origin is definitely of English language (if that makes sense :) ).

    Thanks for the help
