Is it call BIOS or CMOS?

[Gage_5]

My CompTi teacher calls what I know as the “BIOS” the “CMOS” I told him that the CMOS is a battery on the motherboard he said that I was wrong just wanting to know if I am or not

The BIOS settings are stored in the CMOS

No, the BIOS is software stored in a flash chip called an EEPROM. The CMOS is in the southbridge/PCH and is low-power RAM that holds your customized settings. That's why removing the battery erases the CMOS--it's volatile RAM. It doesn't erase/deprogram the BIOS which is good because that would brick it.
