- So, Mr. CS Expert, why don't YOU tell all us ignorant folks what TRUE
- multitasking is, instead of blasting somebody who at least has part of
- it right? Why not explain why "multiprocessing" keeps being invoked
- here, when essentially single processor systems are being discussed?
- I always thought Unix was a multitasking operating system, since it
- can run 2 or more processes simultaneously. True, it is unequal
- sharing due to process priorities, and there is also overhead to
- consider, but one component of multitasking is certainly the ability
- to run 2 or more processes (or tasks) at the same time, at least as
- it appears to the user. Sure, this has to be time-sliced on a single
- processor system so it's only apparently simultaneous, but the comment
- on halving the time should have given you a clue that multiprocessing
- was not being discussed. The Falcon may have a couple coprocessors,
- but I wouldn't characterize it as a system capable of TRUE multiprocessing,
- so I can't understand why people keep bringing it up.
-
- If you have something useful to contribute, please do so; but sniping at
- someone who doesn't have your obviously superior background in Computer
- Science without sharing your expertise seems a bit nasty, IMHO.
