CMOS或互补金属氧化物半导体^{(Complementary Metal Oxide Semiconductor)}是计算机主板中的少量内存，用于存储BIOS设置。它们对您的计算机非常重要，因为它们存储跟踪您的日期和时间以及一些硬件设置的系统文件。那么，让我们看看什么是CMOS，它的用途是什么？详细说明。

什么是CMOS？

CMOS，如前所述，是主板上的少量存储，用于存储BIOS设置。它由N 型^(N-type)和P 型^(P-type)晶体管组成，它们以相反的配置使用。因此，打开一种^{(ON one)}晶体管的信号会关闭另一种晶体管。这样，逻辑器件的设计就不需要上拉电阻。

CMOS有一些优点，因为它具有高速、高噪声容限、低功耗，并且可以在很宽的输入电压范围内工作。

CMOS是做什么用的？

CMOS广泛用于不同的芯片，例如微处理器^{(Microprocessor)}，微控制器^{(Microcontroller)}，静态RAM^{(Static RAM)}等。在计算机中，它与BIOS一起使用。那么，让我们看看它是如何与BIOS一起工作的。

在计算机主板的^{(Motherboard)}RAM上，存在一个CMOS芯片。该芯片继承了RAM^(RAM)的特性之一，它会在您关闭计算机时删除计算机的设置。但是，在CMOS Battery的帮助下，芯片可以持续供电，因此您的计算机设置不会被删除。

因此，当您打开计算机时，CMOS芯片将向BIOS提供必要的信息以启动您的计算机。

CMOS传感器用于许多其他事情，例如在数码相机中将图像转换为数字数据，但在您的计算机中，它用于存储BIOS设置。

BIOS和CMOS有什么区别？

BIOS 或基本输入/输出系统是一个程序，它从启动到操作系统开始控制您的计算机^(System)。CMOS是BIOS存储日期、时间和其他系统配置的地方。

因此，CMOS和BIOS是相关的，但一个是物理芯片，另一个是用于启动系统的固件。

希望我们能帮助您了解CMOS及其用途。

What is CMOS and what is it used for?

CMOS or Complementary Metal Oxide Semiconductor is a small amount of memory in the motherboard of your computer and is used to store BIOS settings. They are very important for your computer as they store system files that keep track of your date and time and some hardware settings. So, let us see what is CMOS and what is it used for? in details.

What is CMOS?

CMOS, as mentioned earlier, is a small amount of storage on the motherboard and is used to store BIOS settings. It consists of both N-type and P-type transistors and they are used in an opposite configuration. So, a signal that turns ON one type of transistor turns OFF the other one. This way, a logic device is designed without the need for a pull-up resistor.

CMOS has a few perks as it has high speed, high noise margin, low power dissipation, and can operate on a wide range of input voltages.

What is CMOS used for?

CMOS is widely used in different chips such as Microprocessor, Microcontroller, Static RAM, etc. In computers, it is used along with BIOS. So, let us see how it works alongside BIOS.

On the RAM of your computer’s Motherboard, a CMOS chip is present. This chip would inherit one of the characteristics of RAM, it deletes the computer’s setting when you turn OFF your computer. However, with the help of a CMOS Battery, the chip can be powered constantly, hence, your computer’s setting will not get deleted.

So, when you turn ON your computer the CMOS chip will provide the necessary information to the BIOS to boot your computer.

A CMOS sensor is used for many other things such as in a digital camera to convert images into digital data but in your computer, it is used to store BIOS settings.

What is the difference between BIOS and CMOS?

BIOS or Basic Input/Output System is a program that takes care of your computer from the time it starts up to the time the Operating System takes control. CMOS is a place where BIOS stores the date, time, and other system configurations.

So, CMOS and BIOS are related but one is a physical chip and another one is a firmware used to boot up your system.

Hopefully, we have helped you in getting a grasp of CMOS and what is it used for.
