What is BIOS?

BIOS and UEFI in computer system example
BIOS and UEFI in computer system example 


The full form of BIOS is Basic input output system is software which checks the all input or output devices running statues which connected to the Computer it is like as firmware if you not know what is firmware then we explain in short form, Firmware is a software which attached to the electronic devices and help it to do some basic work which we program on it

When we start the computer then, first of all, BIOS of the computer is starting and check all components which attached to the computer if all the components in their working condition then the computer will be started so we can say that BIOS is the first software which starts first when we power ON of the computer

The BIOS is also used for booting of the device when we start the computer then before the starting all process which is required to ON the device is called Post (Power ON self-test), after the booting process, the computer is eligible for ON.

The BIOS of the computer is fixed on the motherboard of the computer, it looks like a chip which is called CMOS (complementary metal-oxide-semiconductor) the BIOS chip of the computer is non-volatile (No any data loss when we OFF Computer)

What is UEFI?

The full form of UEFI is Unified extensible firmware interface, it is also a type of BIOS but it is more advance with compare to BIOS so at the present time this UEFI is used on most of the computer and other devices

Difference between BIOS and UEFI

(a) In the BIOS we can do work with the help of keyboard only but in the UEFI we can do work with keyboard and mouse so it is easy to use we can easily configure any setting with the help of mouse but in the BIOS the only keyboard is allowed to do changes

(b) BIOS of the computers are supported only limited storage drives so this is the big reason to replace the BIOS of the computers but at the present time UEFI is taken is used which is supported a large amount of storage drives

(c) In the BIOS the all setting show on the blue screen and the values of the different component are shown in numbers only but in the UEFI the values of the different component are shown both values or graphical which make it too attractive, we can easily see all the details of the computer in the graphical form
