- The Amiga can really only do one thing at a time, like most other
- computers. Its pre-emptive multi-tasking simply means that more than one
- program can be - more or less - progressing more or less at one time. The
- OS pays attention to one, then another, then another. Sometimes this
- means that you can get more done - but only when your various processes
- are using different system resources. A print job and a disk copy can
- proceed together at almost full speed while you set up a rendering job in
- near real-time. Two rendering jobs will proceed together but will take
- twice as long (individually) to finish. And you _are_ running a 7MHz 68000,
- here. System 7.5 does not run on a 68000 machine. 68020, _maybe_. Win3.1
- does not multi-task - though it allows task switching and background
- processing.

-
- This is possible, but not if you are using the WB for the copy. You could
- use the Shell or a utility for the copy then do something else, but once
- you tie up the WB, it's tied up. The OS will still multi-task, but the WB
- (no more than the Amiga's GUI) does not. The latest DOpus has pointed the
- way to individual programs/utilities multi-tasking so that we can look
- forward to the WB itself, and a Shell task, becoming multi-tasking in
- their own rights. (Oooo! AAahhh!)
-

-
- You can do it. You just need to know the limitations as to how you can go
- about it. Oh, and the term "pre-emptive" is the key as to how/why the
- Amiga system is, at least in one way, better than the others. The others
- rely on the "resident" program yielding to another program that it may
- multi-task. Badly-behaved programs do not yield, thus cancel
- multi-tasking. The Amiga OS decides who gets to run when, and for how
- long. Badly-behaved programs have no chance to dominate the system.
- Straight?
