What Is the Purpose of the CMOS? The complementary metal-oxide semiconductor, or CMOS, chip is a motherboard component that stores the basic input/output system, or BIOS, settings of the computer. It comes with its own battery power to retain stored information regardless of the power state of the computer.


CMOS (short for complementary metal-oxide-semiconductor) is the term usually used to describe the small amount of memory on a computer motherboard that stores the BIOS settings. Some of these BIOS settings include the system time and date as well as hardware settings.


Purpose and Contents of CMOS Memory. A great deal of important configuration information is stored in a special type of non-volatile memory, called Complementary Metal-Oxide Semiconductor, or CMOS (pronounced 'sea-moss'), which requires little power to hold on to its contents.


CMOS Settings. The CMOS menu is accessed from the BIOS splash screen. You can typically enter it by pressing F1, F2, Del or Esc. The actual button varies from motherboard to motherboard.


Because the system clock is controlled by a CMOS battery, one of the most common methods of identifying CMOS battery problem is noticing that your computer has a problem maintaining the correct time. Complementary metal-oxide-semiconductor batteries power basic input-output system settings.


CMOS Battery . The CMOS battery (or the motherboard battery) has a unique purpose in a computer. This page will explain what the battery is, how to change the CMOS battery and how to remove the CMOS battery and a range of other things to do with that little computer battery inside your motherboard.


CMOS (complementary metal-oxide semiconductor) is a method of manufacturing microchips, and CMOS RAM is a small amount of memory stored on the motherboard used to hold motherboard settings. This CMOS RAM retains the data even when the computer is turned off because it is charged by a nearby battery.


Complementary metal–oxide–semiconductor (CMOS) is a technology for constructing integrated circuits.CMOS technology is used in microprocessors, microcontrollers, static RAM, and other digital logic circuits. CMOS technology is also used for several analog circuits such as image sensors (CMOS sensor), data converters, and highly integrated transceivers for many types of communication.


The terms BIOS and CMOS both refer to essential parts of your computer's motherboard. They work together and they're both important, but they are not the same thing. Let's take a look at what the BIOS and CMOS are, and how they're different. The BIOS also provides a simple interface for configuring ...


BIOS enables computers to perform certain operations as soon as they are turned on. The principal job of a computer's BIOS is to govern the early stages of the startup process, ensuring that the ...
