All AT computers (80286 processor) or later require a small battery on the system board that provides power to the Complementary Metal Oxide Semiconductor (CMOS) chip, even while the computer is turned off. This chip contains information about the system configuration (e.g., hard disk type, floppy drive types, date and time, and the order in which the computer will look for bootable disks). The CMOS battery allows the CMOS to preserve these settings.
The CMOS chip in your computer is backed up by a battery (like a large watch battery) this only kicks in when the computer is switched off. Since the chip requires VERY little power to maintain its settings, the battery will keep the settings for a long time - sometimes years.
it contains a small amount of memory, or RAM, enough to configuration or setup information about the computer. This chip is responsible for remembering the current date and time, which hard drives and floppy drives are present, how the serial and parallel are configured and so forth. When the computer is first turned on, it looks to this CMOS chip to find out what hardware it should expect to find.
Yes CMOS is available in modern computer. CMOS definition: Complementary metal-oxide semiconductor, or CMOS, typically refers to a battery-powered memory chip in your computer that stores startup information. Your computer's basic input/output system (BIOS) uses this information when starting your computer. CMOS-related error messages could be caused by a faulty or discharged battery. The battery can become discharged if your computer has been turned off for a very long time. To resolve CMOS-related errors, check the information that came with your computer or contact your computer manufacturer. Because your CMOS settings are specific to your computer's hardware, Microsoft can't provide specific instructions for changing them.
