 		 #130472 - Whats an OS?
Responding to: ???'s previous message
The term 'OS' goes back a long way - way before my entry into computing. The term probably predates the use of multitasking and memory protection.

CP/M could probably be better described as a 'disk operating system' as this is primarily what it does.

If we have an 'OS' that is not real-time, what do we call it? Simply 'OS' to differentiate it from a 'RTOS'?

The PDP11 had a variety of OS's.

As an operating system, how would you describe UNIX?

As a noun, OS has many interpretations!
