    What is the key difference between UEFI and traditional BIOS?

    a)
    UEFI is stored on the hard drive, while BIOS is on a motherboard chip.
    b)
    UEFI supports booting from drives larger than 2TB and has a more modern graphical interface.
    c)
    BIOS is faster because it operates in 16-bit mode.
    d)
    UEFI does not perform a Power-On Self-Test (POST).

    Explanation

    UEFI (Unified Extensible Firmware Interface) is the successor to BIOS. Its major advantages include support for the GUID Partition Table (GPT), which breaks the 2TB boot drive limit of the MBR system used by BIOS, along with features like Secure Boot and often a mouse-driven setup environment.
