BIOS (basic input output system) is the menu system programmed into the firmware of your motherboard which allows you to change its settings and input some basic hardware information.

CMOS (copper metal oxide semiconductor) is a type of battery. It is the type of battery most commonly used on motherboards to power the circuit which remembers the BIOS settings and system time. Without a CMOS battery, this data will be lost every time the system is powered off.

In common nomenclature, these two phrases are often used interchangeably. Some people will refer to the BIOS menu as the CMOS menu, and will refer to the CMOS battery as the BIOS battery.
