What Happens When You Turn The Computer On? ⚙

No matter your field, if your job requires you to use a computer, it's important to understand the basics. Here's a simple breakdown of what happens when you press the start button on your computer:

✔ Powering On:
When you turn on the computer, the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) microchip is activated. These are small, essential pieces of firmware that are responsible for the next steps.

✔ BIOS/UEFI:
The BIOS or UEFI microchips contain instructions that initialize the system's hardware, including the CPU, memory, and input/output devices. Once the hardware checks out, the **bootloader** is activated.

✔ Bootloader:
The bootloader is a program that boots the operating system (OS) from your storage device into memory. It essentially loads the operating system so the computer can begin functioning.

✔ Operating System:
Once the OS is loaded, the computer is ready to run applications and perform tasks. The OS manages system resources, including memory, processes, and connected hardware devices, enabling you to interact with your computer.
