The 7 Levels of How a CPU Works How does a CPU actually work? In this video, we break down 7 levels of CPU understanding — from tiny transistors flipping on and off, all the way to modern multi-core, pipelined system-on-chip monsters like Apple’s M1. You’ll learn: 👉 How transistors & logic gates form the basic building blocks 👉 What the ALU really does (and why it’s just a tool) 👉 Why registers, cache, and RAM are like a memory pyramid 👉 How instructions & programs turn simple operations into apps 👉 The fetch–decode–execute cycle that runs billions of times per second 👉 How pipelining & multiple cores massively boost performance 👉 And finally, CPU architecture & SoC design at the highest level #cpu #computerarchitecture #techexplained #howitworks #computerscience ____________________________________________________________ SOME OF MY MOST POPULAR VIDEOS: 💻 Need a fast cloud VM for your own tech builds?
