Yes, but how you time-slice depends on the implementation of "multitasking".

That's "pre-emptive" "multitasking".

No, that's "inter-process communication", which has little or nothing to
do with multitasking.

In your humble opinion.

"True" multitasking is (pick one):
a)  one task per CPU
b)  pre-emptive/no yields/done by the OS
c)  cooperative/yields/time given by each application
d)  when the user can use two or more programs/applications at the same time
e)  any of the above


Have a nice day,
