Question

Quizplus · Accepted Answer

The power-on self-test (POST) is the first-step in booting the computer, and can provide error codes through a series of beeps.
Key Takeaway - Basic Input Output System (BIOS) is responsible for booting the PC. It is stored on an EEPROM (Electrically Erasable Programmable ROM), which is non-volatile, so even without power the information is retained. The POST (Power-on Self-test) provides information to the BIOS on the system's current configuration, providing error codes when necessary. It can provide these error codes via beeps in case the display is not functioning. The CMOS stores the information gathered by the BIOS.
