Jenny remember one thing your the best explainer and if I cannot explained through your lecture then I cannot explain myself anything your the ultimate teacher you are found
System processes are used to run system programs. Ex- Interrupt. High priority system process. Interactive process - When u r interacting with the application.. Like working on MS office. Interacting continuously through console or command, etc. Batch process - Runs in the background. Multilevel queue - Different types of processes are placed in df. types of ready queue. Each queue is having its own scheduling algorithm. "Which queue will follow which scheduling algorithm?" This depends on who is going to implement the scenario i.e, implementer. ( Example - For system process: Round Robin scheduling algorithm) No. Of queues also depends on the implementer. Imp: In a Multilevel queue, if a process is running then from its execution to termination the process cannot change its queue i e it cannot migrate from one queue to another queue. It's permanently assigned to the queue in which the process has arrived. 2nd imp- No interactive process can be executed unless & until "SYSTEM PROCESS QUEUE" gets empty. Same goes with the batch + interactive process. Bcoz of such cause, it leads to starvation. (Disadvantage) We can do "aging". i.e upgrading - To place the process into the next ready queue to get its execution faster. (Migration of process from one queue to another) - known as Multilevel Feedback Queue Scheduling Algorithm. Look, not only low priority process are promoted to the queues of higher priority but also "higher priority process are demoted from higher priority queue to lower priority queue." Go watch how : -2:55 Implementation of MFQ scheduling is tough, it all depends on the implementer. How many queues?, which queue is using which scheduling algorithm, when to promote a process ( after how many time quantum) , when to demote a process, etc. Thank you!❤
Thank u mam, You have cleared my all the doubts and now I am requesting you please make videos on the remaining topics of Operating System. Thanks once again...
Pls complete the playlist... I don't think I will find any lecture on TH-cam which explain so easily like u... Your lectures are amazing😍...God bless u ma'am 🙏
Mam please continue the rest of operating system ..your explanation is very clear very understood and you are the best teacher ever ..please continue this syllabus of Os
Absolutely amazing i enjoined and understood every second thank you so much i have learnt a lot it a short amount of time. Please do not stop creating content you are helping many people many thanks.
Hello Mam, I find your videos very educational. They always provide me clarity on concepts. Can you also please prepare series on Process/Thread Synchronization ? Mutex, Semaphores, Condition Variables, Spinlocks, When to use a particular technique and so on with examples ?
You explained the topics of OS better than my professor. the problem is that my professor is going so deep in OS... Can you do the same please?☺ Thank you for all the work that you have done in your TH-cam account. your lectures are the BEST😁
in the last video, you told that you will discuss disadvantages & advantages of LRU and FIFO page replacement algorithm..but this video is totally different.. can you please make sure that no video is missing?
Tomorrow i have OS exam.... after scoring 25/25 my sir will ask....oh atleast u got to know everything that i taught...very well....and ill say ......no sir...credits to jenny sis.....
Ma'am, Thank U So Much! Bcz Of Your Lectures, I Cover Up My OS Syllabus Upto 80%. And Its really very helpful for me! And ma'am aap bahut cute ho! Plz Ma'am make a series on COA. Plz ma'am
Mam Y u have not completed the Total Syllabus of Operating System . I am sad 😔... Now I want to find a New mentor to complete remaining topics in OS... Thank u Mam For giving a Understanding Lecturer of OS.....Best to give the remaining part ...I don't want to find a New mentor other than you....😕
I have a question, how are timers implemented? Suppose I have a scheduling job, which sends email at 12PM daily. How is it implemented in the OS level? Btw thanks a lot for the videos, really great!.
I understood the concepts very well mam, thanks for these wonderful lecture's mam. I finished the full playlist ,are these videos is enough for gate preparation on operating systems?
Is this playlist incomplete ? I can't find some topics like Allocation of frames, Thrashing, Cache memory, Organization, Impact on performance, File sharing, Disk scheduling, etc. Can you please add those videos ?

you are requested to plz cover rest syllabus ...would be a great help in this pandemic....Your content is crystal clear. appreciable work
Pro trick : watch series on Flixzone. Me and my gf have been using them for watching all kinds of movies during the lockdown.
@Maximo Briggs yea, I've been watching on flixzone for years myself :D
@Maximo Briggs definitely, been watching on flixzone for months myself =)
@Maximo Briggs Yup, have been watching on Flixzone for since november myself :D
don't go for the Flixzone it's a trap by bot

hi , thanks for all your help , I managed to get 95% for my operating systems module at university last semester & it's all because of your teaching 🙏

Nice explanation 👌 nice one...you are the best ...
Finally got...
thank you i really enjoy the you are explaining
Mam, you are doing a great job. You are the gem person of Computer Science. Can you please tell me good book for the Operating System.
Galvin and Tanenbaum.. I think these are very good books with many exercise problems
absolutely crystal clear ❤
You explained the topics of OS better than my professor.
the problem is that my professor is going so deep in OS...
Can you do the same please?☺
Thank you for all the work that you have done in your TH-cam account.
your lectures are the BEST😁
Thanks you mam love from CHHATTISGARH❤️
Your teaching is excellent, crystal clear
Please cover the rest syllabus also mam
Which all topics are yet to be covered in this playlist?
in the last video, you told that you will discuss disadvantages & advantages of LRU and FIFO page replacement algorithm..but this video is totally different.. can you please make sure that no video is missing?
Bro this is one of the cpu scheduling algorithm..
Means this video is actually after the priority scheduling algorithm
Tomorrow i have OS exam.... after scoring 25/25 my sir will ask....oh atleast u got to know everything that i taught...very well....and ill say ......no sir...credits to jenny sis.....
Great efforts prof.
Ma'am pls make video on MRU algo and thrashing.
Wow, Beauty with Brain💗
U r videos was very usefull mam pls keep operating system full syllabus on donig more videos mam
Ma'am, Thank U So Much!

Plz Ma'am make a series on COA. Plz ma'am
Thank you mam for such a great teaching
@8:10 I guess, it should be convoy effect instead of starvation. But, text books also mention as starvation only. Kindly clarify
starvation is the terminology used when dealing with priorities
Mam can you please cover all the topics under operating system..
Mam Y u have not completed the Total Syllabus of Operating System . I am sad 😔...
Now I want to find a New mentor to complete remaining topics in OS...
Thank u Mam For giving a Understanding Lecturer of OS.....Best to give the remaining part ...I don't want to find a New mentor other than you....😕
Mam please complete full topic on OS 🙂🙂
