What does UEFI mean?

Unified Extensible Firmware Interface (UEFI) is a standard firmware interface, designed to replace Basic Input/ Output System (BIOS). UEFI was designed to overcome some of the weaknesses of BIOS, such as speed and hardware limitations. UEFI was initially released as the Extensible Firmware Interface (EFI), a technology developed by Intel for use with their high-end Itanium® line of 64-bit processors, which were incompatible with the BIOS standard. Now Unified EFI Forum is the group responsible for developing, managing and promoting UEFI specifications.
