    The book “Machine Code for Beginners” (by Usborne, 1983) likened computer memory to a shelf or a cabinet with lots of tiny little drawers, all of which can hold just one byte of information at a time. The pictures had robots carrying the information in and out of them, on little pieces of paper. One…
