BIOS Full Form


What is the Full Form of Bios in English?

The built-in software bios stands for Basic Input Output System. It is the first action your computer will take on being turned on. BIOS is the running lifeline of any operating system. The motherboard safely houses the BIOS stored in the ROM. As technology has evolved, the modern computer systems store the bios acronym in the flash memory. 

Different Types of BIOS:

When looking for the full form of bios, you will come across two types of BIOS. Let us talk about them in the following lines:

  • Unified Extensible Firmware Interface BIOS – As shortly knows as UEFI, these are found in modern computers. It can nudge drives as large as 2.2TB or even higher.

  • Legacy BIOS – Truly a legacy, these are the basic forms of bios full form that is found in the older versions of the motherboards. Unfortunately, due to a backdated functioning, these can't support hard drives larger than 2.1 TB. Along with this, Legacy BIOS has a limitation of having a text-only menu in the setup section. 

A Brief History of BIOS to Look Back at:

If we look back in history, Gary Kildall came up with the name basic Input Output System that is the bios full form in English. It was the year 1975 when the first BIOS came out in the CP/M operating system. It defined the machine-oriented parts of the operating system that loaded during the boot time and interfaced with the hardware directly.

Understanding the Work Mode of BIOS:

The rudimentary job of the Basic Input and Output System that is the full form of bios is to nudge the operating system on being turned on. BIOS supervises the opening system of a computer, ensuring the functioning parts are loaded properly. Further, we can categorize the work of a BIOS into the following:

  • The first and foremost work is to examine the computer's hardware for any errors before loading the operating system. This process is known as Post.

  • The second in the line of work is Bootstrap Loader. It passes over the control to the operating system on locating a functioning operating system.

  • Then comes BIOS drivers. These are drivers that give control over the operating system to the computer

  • Then the configuration programs are loaded by the BIOS set up

Software or Hardware- Clearing the Confusion:

The Basic Input Output System so as to say the bios full form is a software that works with the hardware. This software interfaces with the equipment to make the operating system work. It is present in the motherboard in the older versions. But for the sake of technology, these are current n the flash memory of the modern versions of computers so that you can rewrite the contents without removing the chip from the motherboard.
