what does a SM Bus Controller doin easy to understand terms?

when I was using my computer tonight a message appeared saying that my sm bus controller was no longer recognised, I did some research online and managed to force the computer to recognise it again by installing an Intel utility program that came with my computer drivers disk, but I still don’t understand what the sm controller actually does in simple terms and if my computer really needs it

    It monitors temperature and various voltage sensors to be used by the computer's management software. For example, if CPU temperature gets too high, the SM bus controller reports it to the computer's power management system which can reduce the clock speed to allow it to cool down.
