Ce inseamna BIOS, CMOS si UEFI?

BIOS înseamnă sistemul de intrare / ieșire. BIOS-ul este un soft denumit și firmware care este încorporat în placa de bază și care inițializează hardware-ul computerului pe măsură ce computerul este pornit. După ce inițializează hardware-ul, caută un dispozitiv de boot, cum ar fi o unitate optică sau o unitate de stocare, pentru a porni software-ul, cum ar fi un sistem de operare. Așadar, când porniți computerul, acesta execută un auto-test la pornire sau POST. Acest POST (power on self test) este rulat de BIOS.
