A motherboard only contains the hardware to process and control the parts in the computer, your Hard-Disk or Hard-Drive is the part that contains your operating system (Windows or MacOS) and personal information. This is generally a smaller part about the size of a hand inside the computer.
No, most information is actually found on your hard drive, not your motherboard. With out your mother board, however, you do not have a place for your processor chips and fans units to safely be placed in your pc.
what do you mean by this ? motherboards have information about ram processor type of slots on it
but i don't give information if generally gives the name of slots on it
if you are talking about data then all of over pc data is on hard disk
