Thank you Jenny ma'am , I am watching this a day before my exam and you are explaining this in such an effortless manner making everything so much fun to learn

The main drawback of Priority Scheduling is "Starvation"

[@gatecomputerscience1484]

Jenny's lectures CS/IT NET&JRF , right

[@shilpashreeha5798]

@Jenny's lectures CS/IT NET&JRF Ma'am please clarify my doubt that if arrival time of any two process is same how to solve that....please clarify this ma'am

[@jagadeeshmandala4097]

@@shilpashreeha5798 we have to give priority for order in which we have written the process.. I. E if P1 and P4 having same A. T we have to give priority for P1 only

[@bense_tony]

Same Priority, Same Arrival Time. Which one should be considered? Earliest process ID or smallest burst time ?

Thank you ma'am for your guidance. I have been following your video lectures for DBMS , DSA and OS for the past two months. The video lectures helped me, an ECE student, to grasp the concepts. And the video lectures helped me in securing a job in Persistent Systems.

[@soumyadipdeb2084]

such a explanation needs to be highlighted for years.perhaps the best ever explanation available on youtube

Well explained Ma'am, big thanks to you, looking forward for more videos like this, especially in these days where pandemic is still present, just like me, a student who is struggling on online classes. Thank you very much Ma'am.

[@Dattebayo._.]

Thank you mam😊😊..For helping me to get good grade in DSA and now for clearing the concepts of OS also..

[@preathi5436]

Thank you from tamilnadu ❤️ after my 1 hour lectures in college I am still confused about this algorithm but you make me clear in one shot ✨

Its really happy to say that im clear in many topic due to ur videos....thanks for providing it🤗

[@deepakkamatad1680]

Thanks you. Before I was struggle to solve preemptive problems but after seeing this video I understood how to solve this.

[@aleezaymuskan6528]

You just made my exam preparation very easy now m expecting A grade in OS🤩

This lady is not just smart but very pretty! I passed my exam thanks to your lectures! Both non preemptive and preemptive videos were great! best wishes

Thank you Ma'am for explaining it so clearly, you explained it better than my so-called professor

[@arshiraina7021]

Thank you ma'am. The video was just amazing .Everything went inside 💖.

Too confusing question of preemptive but you understand in a very simple way. Thanks a lot ma'am.🙏

hello mam, how we can use this preemptive version for research per-pus? for example there are n jobs and n machines
thanks

On RUclips
Pre-empt, P2 > P1 (Priority) => choose P2
Non pre-empt: P2 > P1(Priority) => choose P1

[@fake.reb129]

is this the long method of preemptive? i saw a lot of video about this topic and yours is different. but i got this more clearer than anyone.

Last process that is p7 has highest priority but in case if was no higher priority than others in ready queue, will it completely scheduled? Or only for one ms??

Thank you so much mam

[@sudarshanhalse4639]

Thank you

[@mujigopinath802]

Could you please explain the scenario and criteria for arriving at Arrival time and Burst time in this model.?
Can we apply this in project management where 70 projects (process) to be completed with 15 developers based on priority which is getting changed frequently.. Could you please suggest a best algorithm to go for this?
To my curiosity what algorithm will be used by IRCTC in online train ticket reservation system.?

Its really helpful ,But please make shorter version of this same topic .. It will be very helpfull to see before exams as a quick revision

In case of higher no higher priority, to solve starvation problem, the priority no of that waiting process after some time interval will be increased or decreased? And the time interval for every processes which are in waiting state will be same or not? PLZZZ REPLY

mam how does the ready queue look like in this case??

If the BT of P5 is changed to 4...then what is need to be done?? The CPU will remain at waiting state till 10nth unit of time??

Mam please reply if highest priority come in p1 then what should we do .....

Great mam

thanks a lot

[@kavithavenki22]

If the burst time of two consecutive processes is same then how to do

[@steveoremo3565]

Thank you ma'am

[@abhinaybehara290]

do we only check the priority of previous process or the all processes which are in the ready queue in preemptive priority scheduling plsss reply

[@pratheekshahl1527]

What if the version is not mentioned in question that is preemptive or non preemptive??

[@shehansampath359]

Thanks ma'am I like your lesson
I think you used to upload

[@user-jm9iw6mm9o]

Thanks mam

[@Rishithabajjuri]

Should we repeat the exercise fr each one?
Like 10 times 1 exercise

[@SangitaThakur-be7oy]

NICE EXPLANATION..
Theres a mistake in remaing time for P5 it would be 11-5=6
