What does UEFI stand for?

UEFI stands for Unified Extensible Firmware Interface. It is a modern firmware interface designed to replace the traditional Basic Input/Output System (BIOS) in computers. UEFI provides a more flexible and robust environment for pre-booting operating systems and other applications.

The term "Extensible" indicates that it allows for greater customization and support for various operating systems and configurations, making it more suitable for today's complex computing needs. UEFI also introduces features like a graphical user interface and support for larger hard drives, which were limitations of the legacy BIOS interface.

UEFI is critical for security features in modern computing systems, such as Secure Boot, which helps to ensure that only trusted, signed software loads during the startup process. This enhances the security of the system against cyber threats.

The other terms listed in the other options do not accurately reflect the standardized definition of UEFI in computing.
