Thanks, Spoon

I have gone that primitive in college. I get how an AC power signal is converted to DC and transformed down to a usable voltage (~5 V usually). I get how that can be interpreted as a digital ON vs. 0 V being a digital OFF.

I have built NOR and NAND gates and worked with transistors in college. Additionally, I still have the textbook to look over that stuff.

I do need to get into memory, and I understand that there are many kinds of flip-flops (FF): DFF, JKFF, RS-NOR latch, etc.

I do not know about accumulators, so that's something I need to look into.

What constitutes a microprocessor? Is it a CPU, RAM and I/O?
