    (A+ in Depth, Chapter 6)

       a)   3 common memory module architectures used for RAN in current computers are:

             _________, _________, and __________.

        b)  The difference between RAM and ROM (in current computers) is ___________


        c)  Two technologies for ROM chips are ____________ and _________________.

        d)  Two categories for RAM chips are _____________ and _______________
              Which of these categories is commonly used for motherboard memory caches?


         e)  Modern motherboards with CPUs running above 800Mhz make use of two current
               technologies for standard RAM called __________ and ___________.

         f)    The _________ cache chip technology includes several types that influence the speed
                and efficiency of the cache.

                _______________________, requires a clock signal and                   

                can use   __________________         or   _____________________ ,

               _________________does not use the CPU clock and provides slower memory access.
