What does UEFI stand for?

Unified Extensible Firmware Interface
User Extensible Firmware Interface
Unified Encryption Firmware Interface
User Encryption Firmware Interface

The correct answer is: Unified Extensible Firmware Interface

UEFI stands for Unified Extensible Firmware Interface, which is an updated version of the well-known PC firmware interface, the BIOS. The other options, B, C, and D, are incorrect because they do not accurately reflect the purpose or function of UEFI. UEFI is a system that initializes the hardware in your computer and boots up the operating system, and it is designed to make the process more efficient and flexible compared to the traditional BIOS. Therefore, options B, C, and D, which refer to "user" or "encryption" instead of "unified," do not accurately describe UEFI.
