UEFI stands for Unified Extensible Firmware Interface. It works exactly the same as a BIOS and both work as an interpreter between the computer hardware and the operating system.

Both are used at the computer startup and they initialize the hardware parts and the operating system. UEFI has one fundamental and basic difference.
