UEFI is essentially a tiny operating system that runs on top of the PC's firmware and can do a lot more than a BIOS.
UEFI is a BIOS replacement on new hardware! UEIF can be stored in flash memory on the motherboard, or loaded from a hard drive or network share when booting. One can say that UEFI has established itself as the successor to the old BIOS and as such enables the central interface between the platform firmware and the operating system, which is very advantageous through the UEIF. This is also the difference between Windows 11 and Windows 10!
UEFI comes from English and is an abbreviation for Unified Extensible Firmware Interface , i.e. the new interface between the hardware and the software during the boot process! This can be seen as a BIOS successor, but it is more, the UEFI has been used on Apple's Mac computers for some time, but UEFI only works with 64-bit systems .
For standard users , switching to a computer with UEFI will not be a noticeable change. Your new computer will start up and shut down faster than with a BIOS, and you can use drives that are> 2 TB or larger.
