Explanation
POST stands for Power On Self Test. It is a diagnostic process run by a computer's BIOS/UEFI firmware immediately after the system is powered on. POST checks that critical hardware components (CPU, RAM, storage, keyboard, etc.) are present and functioning correctly before handing control to the operating system. If POST fails, the system typically emits beep codes or displays error messages.
