🧠 **What *really* happens when you press the power button?** A quick dive into the **boot process** from a computer architecture POV: Check my comments 👇
1️⃣ **Power-On**: CPU resets; starts executing code at a fixed address (e.g., 0xFFFFFFF0 on x86). 2️⃣ **Firmware (BIOS/UEFI)**: Runs POST, initializes hardware, locates boot device. 3️⃣ **Bootloader** (e.g., GRUB, Windows Boot Manager): Loads OS kernel into RAM.
4️⃣ **Kernel Initialization**: Sets up memory, processes, drivers → hands control to user space. From electrons to OS—in milliseconds. ⚡ #ComputerArchitecture #BootProcess #OS #LowLevel #TechDeepDive
