Detailed explanation-1: -Nonvolatile BIOS memory refers to a small memory on PC motherboards that is used to store BIOS settings.
Detailed explanation-2: -A computer’s basic input/output system (BIOS) is a program that’s stored in nonvolatile memory such as read-only memory (ROM) or flash memory, making it firmware. The BIOS (sometimes called ROM BIOS) is always the first program that executes when a computer is powered up.
Detailed explanation-3: -CMOS stands for “Complementary Metal Oxide Semiconductor.” The CMOS battery powers the BIOS firmware in your laptop [2]. BIOS needs to remain operational even when your computer isn’t plugged into a power source. That’s where the battery comes in.
Detailed explanation-4: -The CMOS (complementary metal oxide semiconductor) battery in the computer is used to store the hardware configuration settings. It also keeps a record of the date and time when the computer is switched off. The CMOS battery is inside the computer and attached to the system board (motherboard).
Detailed explanation-5: -CMOS is a special memory chip in the motherboard that stores and holds the BIOS configuration settings.
