⟩ win 3.1 supports which type of multi tasking?
Win3.1 supports co-operative multi-tasking. Once a process
is given the control for execution, the other tasks have to
wait until the current has relinquished its execution.
WinNT is preemptive multi-tasking. A process can be stopped
in the middle if another process needs CPU cycle.
This is handled by the windows OS.
