What is the Full Form of BIOS ?

BIOS - Basic Input Output System


The Basic Input Output System is a first software run by the computer, when the system is turned On. This software is usually stored in the Read Only Memory (ROM), located on the motherboard of a Computer.

The ROM is typically an Electrically erasable programmable read only memory (EEPROM). It allows the contents (bug fixes & upgrades) to be rewritten without removing the chip from the motherboard.
