CMOS & BIOS as interchangeable terms

I have always considered the CMOS and BIOS interchangeable terms and use them frequently with users.  I understand they are not exactly the same but do not understand the difference in detail.  Can someone shed some light on this for me?

CMOS is complementary metal oxide semiconductor and BIOS is basic input output system.  The difference is one of CMOS being a generic term for a type of manufactured electronic component, and BIOS is a functional description of an electronic component.  Early PC BIOS'es were read-only and may not have been made of CMOS, while CMOS chips can be used where they are not BIOS'es.
