What is the difference between UEFI and BIOS?
Unified Extensible Firmware Interface, a form of UEFI, is used. While BIOS is limited to two zettabytes, UEFI is capable of supporting drive sizes up to nine. This is a large amount of data. With UEFI, users have faster boot times. BIOS firmware can only be updated by modifying its ROM, so updating BIOS firmware is tough. UEFI also has discrete driver support.
What is UEFI used for?
As an alternative to the traditional BIOS, UEFI defines a new method of communication between OSes and platform firmware, allowing for a lightweight booting process that only utilizes the information needed to start the OS. Aside from providing enhanced computer security, UEFI backwards-compatibility with most existing BIOS models is another advantage of UEFI.
