    Difference between UEFI and BIOS


    I'm confused with terminology and origin of UEFI and BIOS. I only understand benefits of UEFI.
    Is UEFI part of BIOS?
    Can PC have both?
    Are boot modes parts of UEFI or BIOS?
    Where UEFI is stored on PC?
    Does OS contains UEFI?
    Can UEFI be flashed/updated?

    Strictly, UEFI is not part of BIOS.

    The confusion arises because you have to go to a menu system which historically we called the BIOS when it is really the configuration menu for the BIOS, not the actual BIOS itself.

My computer has UEFI installed but when I go to the BIOS I see an old fashioned BIOS. I thought UEFI was supposed to replace the BIOS. Can someone explain?
