What is Computer BIOS

If you are a computer user, then you should know what the BIOS is and what is the work of the BIOS in the computer. When I told you what a motherboard is? So there was little information about the BIOS. But according to me, there is not enough information to know about BIOS. So today we will learn more about BIOS.

The BIOS i.e. Basic Input Output System is the most important part of a computer. Its main job is to start up Computer Boot Process i.e. to start Computer Start.

With this, it configures all the Input / Output Devices such as Mouse, Keyboard, Scanner, Printer etc. and identifies the Computer which is the Input Device and which is the Output Device. The EEPROM (Electrically Erasable Programmable ROM) on the BIOS Software Motherboard is stored on the ROM chip.

The CMOS i.e. Complementary Metal Oxide Semiconductor is a Battery, which stores all the settings in the BIOS, and with the help of this, the BIOS starts the Computer Booting Process.

You must have seen that even after computer OFF, its time & date does not change.

This is because the setting of Time & Date is stored in BIOS and it runs with CMOS Battery. If the CMOS battery of a computer is bad, then after plugging in, it takes a little time to start the computer and the time & date is also reset.

What does the BIOS work for?

As I mentioned above, BIOS helps in starting the computer and it configures all the Input / Output Devices. But with this the BIOS does many more important tasks that help the computer to run well. for example..

  • Checking Computer Setting and CMOS Setting.
  • Loading all Computer Drivers.
  • Doing power-on-self-test.
  • BIOS Password Set / Reset.

Can BIOS Setting be viewed?

Many people have a question in their mind that how to open BIOS setting. If you also have a question in your mind that “Can BIOS Setting be seen?”, Then the answer is yes, of course you can access BIOS Setting. For this, you just have to restart the computer and you will have to press this key before getting computer boot.

  • Press F2 for Dell PC.
  • F10 (after 2006) & F1 (before 2006) for HP PC
  • Press F2 for Accer.
  • Press F1 & F2 for Lenovo
  • Press F2 for Samsung PC.
  • For Sony PC press F1, F2 or F3.

And in many computers, Computer BIOS Setup can also be opened by ESC Key. Just one thing you have to keep in mind that before the Windows logo arrives, this key press has to be done only then the BIOS setup will open.

How to update BIOS?

Many times it happens that PC does not boot or all its Input / Output Device do not work correctly. Sometimes this happens because the BIOS is not up-to-date. In such a situation, you can find out from the Internet which is the latest BIOS version and which version BIOS is installed in your PC. If you do not know how to check the BIOS version in PC, then you should use these tips.

  • You can go to BIOS Setting and check its version.
  • Press the Windows Logo + R Key on the computer and enter by typing MSinfo32 in the RUN command. System Information Setting will be open You can also check BIOS Version from there.

For information about BIOS Update, you should open the official website of your Computer Brand. From there you will get information about its updation.

Friends, here I have told what is Computer BIOS? And what is its function? With this, I have also told about the CMOS battery and BIOS update. If someone asks you about the BIOS, you can answer it in one word that it works to start the Computer Booting Process and configure all Input / Output Devices. Hope you all have liked these tips.
