What is the Difference Between a UEFI BIOS and a Legacy BIOS

Difference Between a UEFI BIOS and a Legacy BIOS - For those of you who are often involved in the computer world, especially technicians, of course, have you seen a different BIOS on an old computer and a new computer with certain specifications? Yups usually makes a difference, now there is a UEFI BIOS and then a Legacy BIOS.

Usually the most basic when we see the difference between these two types of BIOS is its function to support the hard disk capacity, which Legacy is only up to 2 TB (Terabytes) maximum (that's the Master Boot Record MBR mode), while the UEFI BIOS type can be more than 2 TB (Terabytes) with GPT (Guid Partition Table) mode. The number of newer high-spec computers is usually a UEFI BIOS as it is synonymous with big usage.

Understanding BIOS

BIOS stands for Basic Input Output System. is a piece of software (written in assembly language) that regulates the basic functions of computer hardware. The BIOS is embedded in a memory chip (ROM or Flash Memory made from Comlpimentari Metal Oxide Semiconductor (CMOS) on the motherboard. A battery which is commonly referred to as a CMOS battery serves to keep the date and other settings that we have set in the BIOS from missing or returning. to the initial configuration even when the computer is turned off.

Then what is the Difference Between a UEFI BIOS and a Legacy BIOS?

Here are the differences between a UEFI BIOS and a Legacy BIOS in outline:

• In terms of interface, UEFI supports mouse use and even touchscreen or touch screen while Legacy only supports keyboard only.
• In terms of appearance, the Legacy interface is still standard while UEFI has a more attractive appearance.
• UEFI supports hard disk capacities of more than 2 TB while Legacy bios only 2 TB is the maximum capacity, meaning it can't be more than 2 TB.
• Regarding the hard disk type, uefi is obliged to use the GPT (Guid Partition Table) while the legacy bios uses the MBR (master boot record) type.
• For windows installation, Legacy is easier than UEFI.

That is the difference between the UEFI BIOS and the Legacy BIOS, hopefully what I have explained can be useful and useful for you. That is all and thank you.
