Assume the CPU has 64 data lines. Then Z reading cycles will be needed to load an array of 12 double-precision floating-point numbers, each number coded in eight bytes, from the main memory into the CPU. Z = ?
So I'm looking at some of the past exam questions to prepare for my exams next year and this question (above) has stumped me. I genuinely don't know how to work this out. I know that a 64 bit machine is a lot faster than a 32 bit one but that's about it. Can anyone explain this? (Assume I am an idiot please)
