What is CMOS and difference between CMOS and BIOS

CMOS Full form in Hindi: In today’s article, we will tell you that CMOS what isCMOS battery what would have IsCMOS To Access How doCMOS Of UseCMOS Of Advantages And CMOS And BIOS In what gap Huh,

BIOS In the article we mentioned about CMOS, BIOS is a Software Which happens when the computer is on, booting and hardware Helps to configure. whenever you computer If you turn it on Operating System But the first program to run is the BIOS itself.

All the setting of BIOS is stored in a chip installed in the motherboard which is called CMOS. CMOS chip is a very important part of the computer.

If your CMOS battery gets damaged then how will you know that you will also get to know in this article, so if you are interested in computer then definitely read this article till the end. So let’s start today’s article without delay.

What is CMOS and difference between CMOS and BIOS (What is CMOS in Hindi)

What is CMOS

CMOS, whose full name is Complementary Metal Oxide Semiconductor, is Motherboard There is a Non Volatile Memory Chip installed in it, whose storage capacity is usually 256 Bytes which is very less.

Although CMOS is a Non Volatile memory chip but use it data It is not used to store, but the setting of BIOS is stored in CMOS and apart from this the setting of Date and Time is also stored in CMOS.

Since CMOS is a non-volatile memory, all the data stored in it gets deleted when the computer is shut down. But to keep all the settings stored in CMOS safe, a battery is installed so that all the setting of BIOS and Date & Time stored in CMOS are safe.

The CMOS battery powers the CMOS memory and stores the data stored in it even after the computer is turned off. If the Date and Time gets damaged again and again after turning on the computer in your computer, then it means that your CMOS battery is bad, you need to replace it. By the way, the CMOS battery lasts for about 10 years.

CMOS a little RAM It is like that in which all the setting and information of the BIOS are stored so that the computer can remember and configure these setting while restarting or turning on.

What is the full name of CMOS (CMOS Full Form in Hindi)

The full form of CMOS is Complementary Metal Oxide Semiconductor, which is called “Complementary Metal Oxide Semiconductor” in Hindi.

Different names of CMOS

CMOS is also known by many different names such as –

  • Real-Time Clock (RTC),
  • CMOS RAM,
  • Non-Volatile RAM (NVRAM),
  • Non-Volatile BIOS memory,
  • Complementary-symmetry metal-oxide-semiconductor (COS-MOS).

All these mean CMOS only.

What is CMOS Battery

As we told you that the setting of BIOS and Date & Time are stored inside CMOS, since CMOS is a Non Volatile Memory. Non Volatile Memory is called the memory of the computer in which the stored data is deleted after power off.

Due to CMOS being non-volatile, all the information stored in it is removed when the computer is turned off, and the setting of BIOS and Date & Time becomes default again and again in the computer. CMOS Battery was created to overcome this problem.

CMOS is usually powered with the help of a CR2032 cell battery, so when the computer is turned off, the data stored in the CMOS is not erased.

CMOS has a coin-sized Lithium Ion Battery and its life is about 10 years. Sometimes this battery also has to be replaced. If the Date & Time gets wrong while turning on or restarting the computer, it means that your CMOS battery has failed and you need to replace it.

Failure Symptoms of CMOS Battery

When your CMOS battery gets depleted, then you may see the following side effects in your computer –

  • The time and date are reset.
  • of hardware Driver
  • The computer will find it difficult to boot.
  • Cannot connect internet.

How to access CMOS

in computer to access CMOS Windows A key press has to be done even before it is opened. This key may be different in different brand computers. In almost all brand computers, this key is F1, F2, F9, F10, Esc or Delete.

CMOS Setup will open as soon as you press the key. You can access CMOS from here. If you want to change the setting of BIOS or want to change the setting of Date & Time, then you can do it from here.

What is CMOS Application

CMOS processes were widely implemented and have basically replaced NMOS and bipolar processes for almost all digital logic applications. CMOS technology has been used for the following digital IC designs.

  • computer memory, CPU
  • microprocessor Design
  • Flash Memory Chip Designing
  • Application-specific integrated circuits (ASICs)

Uses of CMOS

Following are the uses of CMOS in computer –

  • All the setting of BIOS are stored in CMOS chip and BIOS is important in booting of computer.
  • Date & Time is also stored in CMOS.
  • Provides all the information about the hardware connected to the computer.

Difference Between CMOS and BIOS

We have told you the difference between BIOS and CMOS through a table.

CMOS (seamoss) BIOS (bios)
CMOS ka full form Complementary Metal Oxide Semiconductor is The full form of BIOS is Basic Input Output System.
CMOS is the hardware that is installed in the motherboard. BIOS is software that is stored in EEPROM.
The function of CMOS is to store the setting of BIOS safely. The function of BIOS is to turn on the computer, boot and configure the hardware.
CMOS gets power through a battery which is called CMOS battery. The BIOS gets power through the CMOS.
