    im literally reading jibberish

    i know its a big ask, but can any of you tech wizards try and dumb this chapter down?

    12

    what I understand is that the program is copying from one memory place and then writing to another but after that it might as well be in Arabic

    pages 12, 13, 14, 15 and 16

    I'm so conflustered

    That is ridiculous!

    There is absolutely no reason a person has to know the microprocessor down to the actual hardware latching.

    The lowest level of programming would be to use the instruction set of a given microprocessor.
    Even that is no longer necessary in today's programming world.
    The programming languages and compilers do all of the work behind the scenes.

    But to look back on simple microprocessor programming ...

    Take an old style, simple processor like the 8085.

    It has an instruction set that is built-in. You use an assembly language programmer to create the program and then save the program in it's memory. Once it is saved, it can execute the program.

    If you look at the 8085 instruction set, you'll see it does the same things as your "Jibberish" processor, but instead of getting down to the hardware latching, you only use the instructions in the 8085 instruction set. Those instructions do all of the bit banging. You only define the command and what it is supposed to do.

    See this example:
    Programs For 8085 Microprocessor Learners

    Scroll down to the "add two numbers". You'll see an instruction like MOV. You instruct it to move a value from one location to another.

    There is a whole instruction set manual for the 8085 that describes what functions it can do.

    You can actually simulate an 8085 online ... learn how to do it:

    Looks like that 8085 simulator is no longer supported ... it used to work.

    You'll be touching on it in college?
    Computer Science I take it?

    Learn to fully understand binary, hex, decimal.
    In particular, conversions and math functions.
