BIOS: Basic Input Output System
The full form of BIOS is Basic Input Output System. It is also known as System BIOS, ROM BIOS, PC BIOS etc. It is the first software a personal computer’s microprocessor uses to get the computer system started after you turn it on. The Basic Input Output System (BIOS) firmware comes pre-installed on a PC’s system board. This software is usually stored in Read-Only Memory (ROM) and located on the motherboard. In modern computer systems, the BIOS contents are stored in a flash memory.
It is not possible for an operating system to continue without BIOS as it is the BIOS that loads the drivers of the hard disk and primary portions of the operating system like MBR, FAT, GPT etc, into the memory to enable the operating system to continue loading itself. It also manages data flow between the computer’s operating system and attached devices such as the hard disk, video adapter, keyboard, mouse and printer. The name originates from the Basic Input/Output System used in the CP/M operating system in 1975. The term BIOS was invented by Gary Kildall. Unified Extensible Firmware Interface (UEFI) is a successor to the legacy PC BIOS, aiming to address its technical shortcomings.
