Today, I learned about important computer terms like BIOS and POST.
- BIOS (Basic Input/Output System) is firmware that initializes hardware when a computer starts and provides the necessary instructions to load the operating system. It’s like the computer’s built-in control center that ensures everything is working before the system fully boots.
- POST (Power-On Self-Test) is a diagnostic process the computer performs during startup. It checks that all critical hardware components, like memory and the hard drive, are functioning properly before the operating system loads.
I also practiced entering the BIOS using a virtual machine in VirtualBox. I learned how to access the BIOS settings by pressing specific keys (like F2, DEL, or ESC) while the virtual machine is booting up.
