Detailed explanation-1: -Nonvolatile BIOS memory refers to a small memory on PC motherboards that is used to store BIOS settings.
Detailed explanation-2: -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.
Detailed explanation-3: -Originally, BIOS firmware was stored in a ROM chip on the PC motherboard. In later computer systems, the BIOS contents are stored on flash memory so it can be rewritten without removing the chip from the motherboard.
Detailed explanation-4: -What is CMOS? Complementary metal-oxide-semiconductor (CMOS) is a small amount of memory on a computer motherboard that stores the Basic Input/Output System (BIOS) settings. The BIOS is the software stored on the memory chip on the motherboard.
Detailed explanation-5: -Traditionally, the BIOS (the computer boot up instruction set) was always stored in ROM because it is non-volatile. However, flash memory (which is also non-volatile, but not read-only) is now often used for the BIOS so that changes to the instructions can be made.
