How does the CPU work?

We will try to understand all the fundamental ideas behind it.

What are CPU registers? How does the CPU work with memory? Why assembler looks like this? What is machine code? How to implement loops and if-else with machine code?

What we will have at the end will be very similar to modern any modern RISC processor like Arm or RISC-V.
