UEFI stands for Unified Extensible Firmware Interface.It is a replacement of Basic Input Output system (BIOS).In the modern computer this specification is for a software program that connects a computer’s firmware to its operating system.In modern PC’s UEFI replace the BIOS.Like the BIOS,the UEFI is installed at the time of manufacturing and this is the first program that runs when we turn on the computer.
Both BIOS and UEFI are low lebel software that starts when you boot your PC and its run before booting of operating system.But UEFI is a more modern approach because its offers faster booting,more security features and supports large hard drives.
