POST - Power On Self Test
Power-On Self-Test (POST) refers to routines run immediately after power is applied, by nearly all electronic devices. The POST is a built-in diagnostic program that checks your hardware to ensure that everything is present and functioning properly, before the BIOS begins the actual boot.
