[@utsavtaliyan7395]

Great Video Sir, but I think Context switches are actually = 3, as P3's burst time is = Time quantum = 2, and P4 also gets completed in only it's first time quantum(so it doesn't get saved after), also we don't save P2 after we execute the 2nd time because it gets completed.

[@maliaqakhan7502]

yeah i thought the same

[@rohanmandloi7561]

I was looking for this only

[@Rayuga-zq8ge]

👍🙂

[@trndsttr7585]

Exactly.

[@ayaredattatraya327]

I don't think so Utsav. If there is expiry of Time quantum, it's called preemptive context switch. If the current process terminates, it's called non - preemptive context switch. Thus, both are considered as context switch..

[@_haptic_shorts]

Great video sir .. ❤ But i think the number of context switching is *4* not 5. Because we didn't save _p3 state_ , coz p3's brust time is 2 so it's terminate there.

[@utsavtaliyan7395]

Context switches are actually 3, because P4 also gets completed in only it's first time quantum, and we don't save P2 after we execute the 2nd time because it gets completed.

Thank you so much. I understood really really well. However I have this question. The p4 here, it was done at 9, and then CPU executed p2. If p4 is completed and then CPU switched to p2, is it still context switching?

Exactly how P3 and P4 context switched?

P3 and p4 never got context switched we brought it in the ready queue based on their arrival time, hence it is only there one time and gets completed when it enters the running queue.
