doubt

Question

is this preemptive or non-preemptive?

 

Comments

Non preemptive process diagrams look like this:

 here we can't remove process A, until it gets in wait state or termination state.

where as in your diagram, an interrupt could remove process.

Preemptive

Answer 1

This is pre-emptive as there is a transition from running to ready when there is a interrupt.
