yes
BIOS configuration data is stored in CMOS memory. That is where all the basic hardware settings are kept. CMOS has traditionally been volatile memory, so a battery is required. Newer BIOSes often use NVRAM.
CMOS or BIOS configuration settings
CMOS battery of your laptop maintains hard disk, time and date, and other drivers and configuration settings in a CMOS memory. You will see these tiny CMOS batteries connected directly to the laptop’s motherboard.
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.
CMOS memory size has increased.
yes it is stored in CMOS
No it uses little power
Modern PCs store the CMOS password in the CMOS memory itself.
