sir,in SJF cpu scheduling even though process p3 has the shortest burst time( 1 unit)instead of taking process(p3) first why you had the taken the process p1 with burst time(7 unit)
starting time of process-arrival time of process. for non preemptive, starting time of p2 is 8 but arrival time is 2 ,hence 8-2=6 is waiting time for p2
Waiting time of P2 is 3 sir. You by mistake took it as (5-2-2) = 1 Correct should be (2-0)+(5-4) = 3 i.e first appearance and it'swaiting time + second appearance and it's waiting time.... And so on!!

Your explaintion . Method is so good I am IT student it is very use full for me thanking you so much keep it up!👍
Its really helpful for me
Thank you so much sir
I am SOMALIA student I learn IT your explanation is so good

Anshul Sharma it’s arrival time is 0
Sir u didn't mentioned the waiting queue of processes after every arrival time, so everyone is getting confused.
sir how to compute throughput in SJF
thank u it is nice lesson
thank you sir!!!
Thank you very much sir
What is the formulae you used in calculating avg waiting time. So it'll be clear cut for putting values..
starting time of process-arrival time of process.
for non preemptive, starting time of p2 is 8 but arrival time is 2 ,hence 8-2=6 is waiting time for p2
nice explanation
can u solve for me 1 Q.if u are available ill send the Photo of Question which i need to solve...
Arrival time are 00, 02, 04, and 05 right ? (in white board, it shows 00, 20, 40...)
it was written like 0.0 , 2.0 , 4. 0 but the dot is not visible.
if it is in a SJF manner then we should have to take P3 as a first in gannt chart is it correct method or wrong? please help me for this
when arrival time is mentioned u have to consider the arrival time in the gantt chart
sir what is the 2nd column in the Arrival time with all zeros ?
Thank you sir , understood
Bro you rock
Sir, in this session the explanation not good there are so many doubts to clarify .
For those who got confused a bit its....2.0,4.0,5.0 not 20 40 50....:)

Waiting time of P2 is 3 sir. You by mistake took it as (5-2-2) = 1
Correct should be (2-0)+(5-4) = 3
i.e first appearance and it'swaiting time + second appearance and it's waiting time.... And so on!!
Accha hua apke lectures free hai wrna hmare paise waste the 😒😒.
Sorry but no clear explanation you have given on this topic
watch his video in series he teaches well to prepare in short time otherwise there is mit video also on youtube why don't you go there
