What is CMOS with full information

CMOS is a software with the help of which the computer starts the boundary, its setting is saved in a small chief of the computer and that chip is called CMOS.

The full name of CMOS is 

COMPLEMENTARY METAL OXIDE SEMICONDUCTOR

 It is a very small memory of a computer whose size is usually 256 bytes, the settings of the bios are stored in it, what type of devices are installed in it and the types of disks installed in it, the culture rate of the system clock in it Time and hardware settings are also in this

 CMOS is like a small RAM in which all brothers information is stored so that every time you restart the computer it can remember its memory. CMOS is also known by other names like

1. CMOS-RAM
2. NON -VOLATILE RAM (NVRAM)
3. NON -VOLATILE BLOS MEMORY
4. REAL TIME CLOCK (RTC)

CMOS is a memory in which some things are stored and there are many types of memory like NON-VOLATILE and volatile memory

Volatile memory is that which does not have a data address even when it is powered off and non volatile memory is called as one in which the data address is reached when power is off, then what is more is a non volatile memory which means whenever it is in it If there is no power, then whatever data is in the chip will be exhausted, then its data will never be exhausted and to keep it getting power, a battery is installed in the motherboard which is only made by CMOS to fulfill its function. We call CMOS battery, CMOS is an advanced technology battery that works at very low power cost.

 what is a CMOS battery and how does it work?

 As I have already said that the CMOS setting remains inside the chip, apart from the settings of the bios, there is also the storage of date and time, so if there is no CMOS battery, then when we shut down the computer then the CMOS will also finish all its settings Because CMOs are a non-volatile memory whose data is lost when power is not available, this battery is designed to overcome this problem.

This battery lasts very long because it is very difficult to change the battery of CMOS battery of a laptop computer. CMOS daughter is a coin-shaped lithium ion battery and its life is usually only 10 years but sometimes it Even before it goes bad, how the system is being used when it goes bad depends on me, it can be replaced if the CMOS battery is bad.

When the CMOS setting goes bad, Jai is also set to the bio setting, in which your computer will work but as the date and time functions will be reset because whenever you change the bio configuration of your computer then that CMOS setting in its chip Saves not on the chip of the boy's, so the computer can remember all its configurations every time the power is restarted, so the Siemens battery always supplies power to the bio even when power is off continuously.

Now we will know how to access CMOS. After accessing the CMOS, footing on we have to press one of the keyboards such as F1 F2 F9 F10 AND Esc. Who is pressed differently in different brands of computers. On pressing, you will reach the bio settings of the computer from where you can change the system and timing and date and in this you can also enable and disable many types of hardware such as USB board video card sound card other devices

 what is the difference between CMOS or BIOS

Bios basic input output system

Mainly used to start the computer and it also commands all input and output devices. The computer only knows by bios what the output is.

> Both bios and CMOS are different components that work together.

 > Computers without bios could not understand how all the CMOS of gaa would         work

> The job of the CMOS is to secure all the battery scores that continue to power             them even when the computer is off.
