I've been watching these amazing videos in the hopes that I too will pass. Sometimes I get discouraged but when I see and hear others succeeding the fire is lit once more.

apparently 32 bit processors are a thing of the past ? I can’t find the current state of which is most prevalent

I have a question about the diagram at 3:24. My coworkers told me that while L1 and L2 cache are stored in the core on modern processors, the L3 cache is stored on the motherboard. However your diagram shows the shared L3 cache as being a part of the CPU itself. So where exactly are all of these caches stored? I'm gearing up to take the exam this or next weekend and your videos have been a huge help.
