Best ever lecture

[@prasadpathak3658]

@8:55 what does time 0+ means?

[@shahbros1498]

Nice way of reaching.

[@MobilePanda]

What will be the context switches in the first question ? Please answer

[@akshaykushwaha7003]

Start 7:15

[@crazymemes4080]

nice buddy 😄 time Saving

[@sachingaikwad9288]

In Round Robbin Scheduling Algorithm
lets consider if a process is executing and now its preempted and the next process for execution is the same process in this case will we consider the context switch or not ?
eg. | p1 | p3 | p4 | p2 | p2 | p5 |
how many context switch in this case ?
5 or 4 ?

[@ayushpratapsingh2540]

I think 4 as context switch is not happening

[@SoloScholar0202]

4 of course since p2 is running continuously, it won't come under the context switch.

[@rahulray7421]

Right answer is 4 because PCB of the process p2 switch only one time and it execute two times cause of RR.

[@wigglesort]

5. sir told in the video

[@sumitrajsingh938]

Sir poore syllaabus ka video daaliye

[@dsadaddy8403]

how come the fractions are multiplied to get p^n

[@gayathribijivemula]

Cpu waiting time for 1 process -p
For 2 process-p*p
For 3 process-p*p*p
For n process-p*n

[@darkrider3070]

In short - Using PnC
Detailed - Each process needs to wait for time p before execution and in all there are N processes. Also each process needs to be executed one by one separately(we cannot move on to the next process before completion of the current), so Applying Fundamental Principle of Counting(for Multiplication) of PnC we reach the conclusion :
p * p * p * p * ........... n times = p^n.
