Teaching better then many PHDs.

[@AniketMondal1995]

Ravindrababu Ravula you're the real MVP

[@mysticstardust1109]

20:46 should be 18-6 = 12. :) for those that are confuse

[@nayansengupta9911]

the coolest teacher ever..thank you for making it so easy! (y)

[@jabbinfathima3357]

U r the best.. Young and genius.. Thanx a lot for making this easy

[@harshitmalviya3807]

u r uncredibly awesome !! nailed it !! :) thnqq .... phli bar koi cheez itni asaani se samjh aai h :D tnqq soo much

[@sum1ch.949]

Best video ever. I already understand by looking at the subtitles

[@thembiemadziwa988]

helpful indeed. Big up from Zimbabwe

[@saeedhashemi9682]

Teaching better than college professors keep going

[@saadmanahmed860]

iconoclastic illustration. You are a real super hero for teaching

[@kahlilugsad942]

Great explanation sir! I only had 1 hr left to study before exam and I understood it. :D

[@kanchamjathinreddy7406]

superb teaching sir....untill now i have seen many videos on round robin ....but not in single video i understand......after watching ur video ....i understood completely and now i can solve any type of problem in it ...thank you soo much sir

[@dddiehard02]

Amazing tutorials, please don't stop making them!

[@m1rchegfn]

I don't know if I am going to pass my exam on 20th June, but this video was super helpful! Congratulations for making it!

[@susenakodumuri2667]

Extremely awesome sir... So many videos were there but they didn't give clarity to me. But I. This video I got it...

[@rajbrothers5113]

here TAT for P6 is 12 not 13, nevertheless as u mentioned there might be mistakes in maths but the concept is clear, thanks buddy

[@pujanshah4664]

Awesome work. Thanks for teaching us brother

[@eugineakediodongo2832]

Thank you for this, you've made my work easier!!!

[@srisravya9901]

first time, i m understanding the whole procedure of round robin calculation. thanks a ton!!

[@animalcarecenter4607]

16:30 the time p2 is over the time is 6, how come? I dont get it.

[@bhagwatdhavale6091]

proc execution priority are depends on arrival time then it's sequence are p1,p2,p3,p4 ,p5

[@mr_pawar_3]

I am just like u bro..... really I understand every one what ever I know clearly and heartly​......ur cool

[@swapnilmandal4711]

thank you sir , your way of explaining things is really wonderful

[@iwas23]

Great video, so thankfully for this man, thank you so much

[@AayraAndMom]

sir why p4 is not put into queue after p2 and p3 ??

[@mr_pawar_3]

actually many teaches​...just what ever they know. but they should teach us like how they had understood. maintain same not for others only for u so that u can love yourself that u are good character​ed person.

[@mbohblesspn4887]

Oh man this has changed my knowledge thanks allot

[@satyakibose8402]

for TQ=4, the TAT of P6 should be (18-6) = 12, not 13.

[@mdsaifalam9823]

sir to lecture m hi bol diye h thoda misprint ho skta h concept sahi h n...(18-6)=12 hi hoga

[@ZoneInOn]

Satyaki Basu this is for when the TQ is 4, for anyone wondering, during the second example he gives near the end of the video.

[@vhiteshmore9458]

Bhot hard sir ji, clg chod ke apke videos hi dekhne padege.

[@otiasammy]

sir! EXCELLENT work!!! big applause

[@deezerzgaming810]

You taught more in 20mins than my lecturer in 3 hours

[@shivakumar-zb8ii]

Professor u r best than our faculties

[@MohamedAjhar]

3:57 RR also depends on BT like SJF ?

[@mohamedabdul633]

genius explanation, i dont know where I can accesses your tutorial

[@akshatha.c.bharadwaj5390]

classic teaching!!👏👌👍

[@preethimathiyarasu7486]

Thank u very very much Anna was very useful and clear

[@tunedstrings5132]

Sir i want to ask that from where we came to know the burst time? As u teached that it us not predictable which is also the reason for the failure of SJF

[@yashbehara7525]

Learned it in 5 min.... thank you!!

[@iamPramuk]

Very helpful indeed ! Thank you so much :D

[@LoKing96]

Very detailed .. thank you so much :)

[@ujjwalrustagi8690]

Nice explanation. Thank You Sir!!

[@vikassemwal1947]

Really helpful for my exams thanks a lot...

[@vijaykumar4-yrb.tech.elect264]

In sjf you said that we can't know burst time earlier without doing the process then how you are giving condition that if process terminates before time quantum time You come out from that process less than time quantum?

[@asandaLFC]

THIS GUY IS EXCELLENT

[@KaranSingh-qu6uh]

your explation is really ossm...

[@kavithakatla7533]

Considering p1 at 4th is wrong because in round robin TQ is allocated to all processes in one cycle

[@AsquareM]

No it depends on arrival time, you're dumb.

[@namandeepsinghhora8956]

excellent teaching skills thanku sir

[@Truth-qe6sf]

can someone help me to solve this 1. Assume that there are n processes in a ready queue when the time quantum is q. A. Determine the average wait time of the processes. B. Determine the wait time for a new process if the process goes back to the beginning of the ready queue. C. Calculate the average turn-around time if the execution time of processes is m. When the processes are finished, assume that they are executed sequentially. D. Calculate the average throughput using the above results.

[@alexandrumuntean7565]

Question : How can we determine the optimum time quantum ? is it 80% of AVG(BT)?

[@frittatas8551]

really nice and thorough explanation

[@CuriousGirl-g2g]

Life saving during exam.

[@AmitChaudhary-qx5mc]

sir u are doing a great service. please upload more videos

[@PavanKumar-zd2sy]

Sir, When priorities are provided for process. Does we need to follow priority or fcfs while performaning round robin?

[@hafiznoumanshakoor9298]

make an example of round robin include arrival, time burst time and priority time.

[@mosaletswalo7764]

The beauty of math you don't need to know the language, just understand the numbers :_)

[@heisenbergwhite9310]

You are great sir...thanks a lot♥️

[@Kususasikala]

tqq so much.it was very helpful for my exam.

[@muskaantayal4614]

Sir u r the bst...m ur fan sir😍😍

[@sohammondal406]

Sir , still in round robin I am requiring BT as I am comparing again again with TQ. You said SJF is difficult to implement because we require BT beforehand. So how round robin is being implementable.

[@navkaransingh3948]

pls tell if u have found the answer

[@RickConvenience]

Thanks, u save my SOs proyect

[@Harsha-kg5rv]

I have a doubt. When there is no arrival time can I assume arrival time for p1,p2,p3 is 0,1,2 respectively or for all arrival time is 0

[@GottaBeLouuu5]

excellent explaining!

[@abmshihab6713]

I have a question. What if there is no time quantum given ? can we consider any by default time quantum value ?

[@AyushKumar-qs7gx]

is it possible to use less time quantum for large no. of processes and large time quantum for less no. of processes?

[@garimadhankar301]

plz correct the processor 6 TAT(CT-AT) i.e. 18-6=12 & WT(TAT-BT) i.e 12-3=9 in second example( where TQ=4). @Ravindrababu_ravula

[@professor549]

mistake in (time quantum 4) tat is not 13 it will be 12 and in wt not 10 it will be 9 but u explain very well

[@backgroundnoiselistener3599]

simple and accurate. Best.

[@nishajaiswal4424]

Thank you sir... It was very helpful

[@gaganbhattarai6101]

if the burst time of p1 is 5 we have to add the p1 in queue after p5 or not?

[@mayanksaraswat113]

what if the arrival time isn't given in the question?

[@oishikeebanerjee8937]

Mayank Saraswat take arrival time=0

[@ambatirakesh5597]

Sir what is the case if the arrival time for P1 is not zero then in the gnatt chart from we should start

[@santanubarik2235]

If a two process has same arrival time ' 0 ' then which process going to be taken first???

[@babin9530]

while tq==2 why you do p1,p2,p3,p1,p4.... but not p1,p2,p3,p4,p5.p6,p1..???

[@kaushikreddy2642]

what if all the processes have arrived at same time???? then can we follow shortest serve first approach

[@utkarshparekh4710]

Hi What is the response time? And How to calculate that?

[@khannawaz2600]

Many thanks . Best Explanation

[@edwardlucida4949]

Correction in TAT= 18 - 6 = 12

[@flaviouscorreia536]

for which process buddy entire algorithm is perfect

[@neon0wl2107]

TAT=CT-AT; 18-1=17

[@neon0wl2107]

TAT=CT-AT; 18-1=17

[@NamNguyen-tv5ie]

do u have banker algorithm video?

[@anuraagsingh1263]

is their is any particular number to get at in the last??

[@aakashkotiya02]

really great videos thanks for this...

[@zaidisyed8695]

If we have time quantum 17.75 then can we round off the value ?

[@viranjankumarakela701]

If arrival time of all process is greater than 0 ,how will you start

[@nawabonkashehar831]

Sir why u not use after the p1, p2, p3, p1, then p2 is coming why put the values p4 and p5..?

[@SmritiChatterjeefairy93]

shouldn't the TAT of P6 be 12(18-6) and WT 9?

[@iqratanveer2308]

plzzzz I hav an prob if Arrival time is 1,2,4,5,6,7 of 6 processes and Quantum time is 1 then what be the solution?

[@taimoormughal7271]

THAnk you sir for clear my confussion

[@shreeshkulkarni2547]

sir what happens if any interrupt will occur during its quantum?

[@anamikaunnikrishnan4268]

Is there any different method...or the same u explain?

[@suyogmane5879]

After 2nd P2 there should be P5 before P6 because P5 is 6-2=4 still remaining

[@harismansoor3584]

Hello dear.Kindly tell me if 2 processes in Round Robin have same arrival time then what should we do? either we use the process with smaller Burst time 1st or process with Larger B.T 1st ?

[@harismansoor3584]

@@ravindrababu_ravula if you dont want to reply here no problem i will ask to other person on youtube thanks.

[@tesspradeep]

i couldnt get the order that took in the que.?

[@bassmadalin3000]

Hello. how do you find optimal quantum if its not given? Good job otherwise

[@usmanfarooqi244]

Sir very well teaching

[@ongweiwen9891]

Thank you! Helps a lot

[@protikhansda9571]

in RR scheduling which one will execute first when the arrival time is same for both processes?

[@santhoshsan9958]

All the processes executes once and depending on TQ preemption occurs on there respective processes

[@skmgamer8214]

sir.. why after process P3 again P1 while come ? why not P4 ?

[@icscybersecure]

What happens when you add priority into the table?

[@mdsaifalam9823]

Thanks Sir Dear sir wo P6 m thoda misprint ho gya h n sir concept bahut achha h sir......

[@RajKishor-ls1vz]

Chha Gaye Bhidu... Pass kra diya aapne OS ka Exam...

[@shreeshkulkarni2547]

sir what happens to the remaining one quantum of time for p4 is it considered as an idle time for the processor pls answer ASAP

[@RIPRandomInsanePranks]

No, CPU will not remain idle for 1 second instead it takes the next job
