What is UEFI?
UEFI's full Unified Extensible Firmware Interface. UEFI is the newest version of BIOS. It is used in modern motherboards. Now the question is what was needed to make it new to have BIOS. Since BIOS was used in older computers, it had some limitations. One of these is to support the drive. Previously, hard drives of computers used MBR or master boot record partitioning schemes. This partitioning scheme can only be used on a hard drive of 2 terabytes and 4 primary partitions can be
created. To solve all these problems in modern times, new partition scheme GPT has been created with UEFI. This allows you to use a hard drive like Terabyte or Petabyte Jetabyte and create a maximum of 128 partitions. UEFI is created using animations with a graphical user interface. It can be controlled using both mouse and keyboard. Here you can see more information including processor temperature, voltage, motherboard fan speed.
