classifying operating systems

An operating system could be described as a series of events that occur when a computer is turned on.

If a number of computers are set up with the same operating system, we might assume the same events would occur when each is switched on, for some number of steps.

A group of computers that all performed some number of identical steps before some of them began performing different steps could be said to share the same operating system up to a certain number of steps.

All existing computers could be classified as belonging to one of a finite number of operating systems as just defined.
