Did you intend to ask about RAM or did you actually mean ROM?

A computer motherboard contains both RAM (typically between 2 and 4 GB) and a small amount of ROM.

RAM = Random Access Memory. The memory used on a computer motherboard to hold programs and data while it is running. This memory is said to be 'volatile' because when the computer is switched off and there is no power available to the memory all the stored information is lost.

ROM = Read Only Memory and is essentially non-volatile, that means when the power is removed the data remains as it was and can be accessed again when power is restored.

Computer motherboards use ROM (strictly EPROM) to hold critical files and settings for the BIOS.
