UEFI stands for Unified Extensible Firmware Interface. It is a newer firmware standard that has largely replaced the traditional BIOS firmware found in most IBM compatible computer systems. UEFI is designed to provide a more flexible, secure, and efficient way of managing the hardware components and launching the operating system.
UEFI offers several advantages over BIOS, including support for larger storage devices, faster boot times, and improved security features such as Secure Boot, which helps prevent unauthorized software from loading during the boot process.
A more user friendly user interface makes it easier to configure and customize the firmware settings, such as boot order, system clock, and power management options. This can be done with a mouse or keyboard.
