This person is so dedicated that even the lines on the board are drawn using a ruler. Thanks a lot for providing such nice content. Respect 🙏🏻

Round Robin is like PaniPuri wala giving Puri to everyone standing there one by one And FCFS is like ticket counter , you came first so you can buy ticket first , And SJF is like grocery store kaam saman waley list ko pehle de deta hai

[@Parth-z1k]

Best teacher on youtube for operating system

[@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..

[@nihalmuhammed4354]

When we count the no. of context switches, do we also count where a process gets terminated and a new one comes in (like P1 after P3)?

[@Kumkumbinjwa]

I was searching for this question in comment section . Did u got ur answer ??

[@monilgandhi229]

Even I have same doubt....can you plz share the answer if you have got your query solved

[@nihalmuhammed4354]

Yes, we do count them. It just means that CPU is switching from one process to another(whether preemption or termination)

[@amanmotwani4727]

i also have a same doubt....if somebody knows about it , then please clarify...btw i love the way you teach sir❤❤

[@utsavtaliyan7395]

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, also we don't save P2 after we execute the 2nd time because it gets completed.

Sir how P3 process gets context switched, it gets terminated there.

[@YashKumar-iw4zd]

Very nice explanation Varun Sir, just please clarify the above point and also similar kind of case was with P4

[@sarojshardha3549]

Exactly how P3 and P4 context switched?

[@talhaanwar6427]

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.

[@_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.

[@nuzattasnim3942]

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?
