The items I referred to fire up when the machine loads the OS and nothing can or will stop that. They are all elements of a OS that supports multi-job environment. To compare a single Intel CPU to a machine that has many "processors" just can't be done and that was my point. I have been using PC's long before they got to be a commodity based product. (Late 70's early 80's) I am well aware of what they can and "can't" do. If you have ever seen any NT machine with a single processor running more than one job at a time, you and I don't have the same concept of multi-processing. Task swapping is NOT multi-user. It creates the illusion of multi-user but it's not the same. W/xx or NT(Nice Try) remain what they are and in fairness to them, should not be compared to a real OS. > Btw, laptops do have spooling, communications for various devices (modem, > ethernet, etc), can handle multiple users (Georgia Softworks has a telnet > server for NT I've used), are keeping track of hardware & software interrups > and doing something about them when they happen, etc. And a laptop could run > 5 simultaneous occurrences of the same program.
