You are the best! Day after Tomorrow I have a job interview fealt like wouldn't be able to revise anything in os but the level of clarity with which you are teaching is phenomenal ! Seriously so helpful!!!!
the main helpful point of this OS series is ki: jav jav old topic occurs hue hai.. wo dubara revised kraye hue hai ,, esa nahi bola ki pichli vedio dekh ke aao ( ONE OF THE GOOD PART OF THE SERIES)❤
koi bhi babbar bhaiya ke break-up ke baare me baat nhi kr raha hai ... 😢 ab kaise ho bhaiya? hota hai sbke sath.. kaam ko priority dene wale laDko ke sath aisa jaroor hota hai.. koi baat nhi bhaiya dusri aayegi.. be positive.. . . . . . AND A BIG BIG THANKS TO BOTH OF YOU FOR THIS SERIES ❤❤ (gustaakhi maaf! 😜🙏)
A zombie process refers to a process that has completed its execution and waiting for its parent to collect its exit status, whereas an orphan process is still in its execution phase even after its parent terminates.
Koi baat nhi love Babbar bhaiya padhai to kar na padge ga this line is Epic 🤣🤣🤣 please bhaiya video ka beech beech mein joke kar ta rakhen bhaiya maja a ta haa ❤️😁
its really nice to see the hands on experience from terminal. no other creator has done it.. but it would be really good if you include terminal of windows.. since many use windows it will be easy for us to understand and also to practice by our own. just a suggestion :))
The example used for context switching in the beginning (music and swiggy) is more relevant for context saving rather than context swtiching.Correct me if I am wrong.
Sir you told that any parent process calls wait command to know the exit status of child process. What is time after which any parent process calls wait command. What are the factors that decide the time for calling wait command.
Doubts: 1. Init hi bss eklauta parent process hota hai OS me?? Kiuki baaki sab process hi kisi na kisi parent kah child hai 2. Agar parent process me wait() nhi rehene ke karan bahut zombie process table me reh gya...toh uss time kya system crash ho jayega? Usko ultimately kaun handle krega??
Ans: 1. yes init is the only parent process in the system, rest all are the child process of this zeroth process. 2. System crash is bit extreme word, infact if there are too many of zombie process, the process table which is finite in number, at some point of time will become full, hence making it unable for OS to run other processess. I feel, u by now, might have come up with a solution to these questions, but still for the reference of future readers, i wished to highlight this.
In last zombie process example, you are calling sleep 1 with &, why is it not created under main init process ( pid 1 ) ? Why its parent process id is still pointing to the script pid ?
When u have used "sleep 1&", why is the PPID != 1 ???? Ideally all sleeps should have been independent processes and zombie.sh should not have called wait() for them. Init() should have called wait for them. please explain where is the gap. Thanku in advance bhaiya.
in the hands on of the zombie process why did we use sleep 1& instead we could use sleep 1 right?? bcz it makes the process detach from parent process rightt????
& will create a new process... In the orphan example, it's cleared with ppid 1 But in zombie example, the ppid is not 1 for the new process created using &. Can you explain... Why is that....????
@sufyaan khateeb yes I understood this part... But as lakshay sir told that there will be a resource leak if the parent exits first...? But if the parent exits in the above zombie process code.. Then all 100 (sleep 1 &) parent will be init..all the process will give the exit status to init and entries will be removed from the process table.. So how come there will be increase in process table(why would the process entries will not be deleted) .. It will be cleared like before..
Bhaiya orphan process mein vo uss child process ko seedha terminate kyu nahi deta. Jab uska parent process hi nahi terminate ho gya to child process ka to kuch use hi nahi raha jaega...
With exec and child process spawned with an &, does the parent process here wait for the child processes (the zombie processes)exit status even without using wait()?
sir swapping me process swapped space me jata h ,but i want to ask that jo process swapped area me move ho rhi h wo kaha se hoti h,ready queue se direct swapped space ya phir cpu me jaane k bad swapped space me jaati h .
Best O.S playlist for placement,
Quality Content and consistency🔥

Attended all os lectures till date
Consistency op 🔥🔥
And amazing thumbnail 🤩🤩
Thanks a lot for all efforts
koi bhi babbar bhaiya ke break-up ke baare me baat nhi kr raha hai ... 😢
ab kaise ho bhaiya?
hota hai sbke sath.. kaam ko priority dene wale laDko ke sath aisa jaroor hota hai..
koi baat nhi bhaiya dusri aayegi.. be positive..

tujhe kese pta chala breakup ke baare mein??
Bhai tujhe ek bandi ki bhut need hai🤢
Sabke Saath nahi hota hai ;(
OS videos consistency OP !!!! keep uploading bhaiiii 🔥🔥🖤🖤
Bhaiya mazza aa gya. Kaafi OP lecture tha.
Agle lecture Ka behadd intezaar rahega :)
Started a little late but finally caught up with the course. And by the way thank you the course. Now also expecting the DBMS course to come.
Announcement done starting from June ….. Yay!
present bhaiya! your all OS lectures are superb, thanks for all your efforts
this complete playlist is very beneficial the explain and notes both are soooo accurate
I have not seen such level of content till now
Lecture and consistency is good just one feedback just zoom the screen while you code on terminal it isn't visible enough to see all process happening
A zombie process refers to a process that has completed its execution and waiting for its parent to collect its exit status, whereas an orphan process is still in its execution phase even after its parent terminates.
what a video all concepts get cleared
Koi baat nhi love Babbar bhaiya padhai to kar na padge ga this line is Epic 🤣🤣🤣 please bhaiya video ka beech beech mein joke kar ta rakhen bhaiya maja a ta haa ❤️😁
babbar bhaiya ka breakup ho gya or tmko maja aa rha 😥
Great concise playlist. Really useful for non cs peeps
Amazing course. Waiting for Networking course😍😍
Terminal me kya karte ho kuch samjh nahi aa rha. 😖😖😖
Thank you bhaiya, your efforts are highly appreciated
its really nice to see the hands on experience from terminal. no other creator has done it.. but it would be really good if you include terminal of windows.. since many use windows it will be easy for us to understand and also to practice by our own.
just a suggestion :))
Swiggy wala example was op!!!
18:12 Love this banter
excellent explanation, windows -> maximum process ID is 2^24 (16,777,216)
The example used for context switching in the beginning (music and swiggy) is more relevant for context saving rather than context swtiching.Correct me if I am wrong.
Babbar bhaiya op 😁 break up💔

Bahot sahi content! ❤
Really loving your efforts 🎉🎉🔥🔥

Attandance marked OS considered consistent ✅
Nice session...🙌
Thank you Lakshyay Bhaiiya !!
HomeWork: The number of entries in windows process table are total 8 entries & in LINUX there are 512 entries
source pls? cannot find
you are a motivation for us bhaiya
Nice video. Good hanson concept.
The best 🔥
ultimate bhaiyaa!!
Take care Love Bhaiya
The default number of maximum table entries in the process table ranges from 10,000 to 32,000 in windows and 4096 in Linux.

best os playlist
Really very good content.
quality🔥🔥🔥
The os playlist is awesome. but please try to make the video regularly like in a week at least three videos sir.
Best os course
Best explanation
In last zombie process example, you are calling sleep 1 with &, why is it not created under main init process ( pid 1 ) ? Why its parent process id is still pointing to the script pid ?
Thank you so much bhaiya 🙃🙃
Bash prg. ka bho ek course leke aao plz
Awesome content!!!

Maza aa raha hai Padhne mai sirji
Bahot nend aa rahi thi love bhai ka break UP sun kar nend hi cali gai 😅😂
When u have used "sleep 1&", why is the PPID != 1 ???? Ideally all sleeps should have been independent processes and zombie.sh should not have called wait() for them. Init() should have called wait for them. please explain where is the gap. Thanku in advance bhaiya.
bahot mast video he
awesome teaching
Wonderful Content ;)
sir, degree of programming is no of process in ready queue or no of process in memory which can go to ready queue?
Number of processes in the ready queue.
the way babbar said "break up" 😂😂
in the hands on of the zombie process why did we use sleep 1& instead we could use sleep 1 right?? bcz it makes the process detach from parent process rightt????
& will create a new process... In the orphan example, it's cleared with ppid 1
But in zombie example, the ppid is not 1 for the new process created using &.
Can you explain... Why is that....????
Please revise the video, you will find the parent of "sleep 1& " has not exited.
@sufyaan khateeb yes I understood this part... But as lakshay sir told that there will be a resource leak if the parent exits first...?
But if the parent exits in the above zombie process code.. Then all 100 (sleep 1 &) parent will be init..all the process will give the exit status to init and entries will be removed from the process table.. So how come there will be increase in process table(why would the process entries will not be deleted) .. It will be cleared like before..
@@lakshaykumar7518 thanku .. I got this part.. I have one more query.. Kindly help to reply.. I added just below it.
Thanks in advance.
CPU can handelmaximum 2^22 processes.
Why parent process (waiting for child's status) did not immediately read the status of child ?? And letting the creation of zombie process ?
majja aa gaya
In Progress.....
You just wrote command in terminal but did not tell anything about that program and what are it's syntax and how to write code
Thank you bhaiya!
Bhaiya orphan process mein vo uss child process ko seedha terminate kyu nahi deta. Jab uska parent process hi nahi terminate ho gya to child process ka to kuch use hi nahi raha jaega...
What if that child process is doing something really important work.
Amazing👍
Bhaiya handwritten notes update nhi hue av tk?
Kal bola tha aapne update krdunga😁🙏🙏
Let me check
Check Community Post, Added all notes there
Thank you very much bhaiya ❤️❤️😁
bhiya mujha sb smj agya orphan process or Zombie process but ik doubt h ki koi process apni child process kyu banati h
please explain
Ye Lakshay bhaiya ek progrma command main run kr rahe orr ek orr kha run kr rahe hai ...?
18.35 point to be noted
maza aagaya bha
Attendance marked sir !
The orphan process demo didnt work for me in WSL :(
Is on-hands part is important for the interview ?
Keep uploading vaiya
Best explanation 🫡
Job queue is in secondary memory or main memory?? please confirm
Bhaiya moj kr diii
Hum first hum first😅
With exec and child process spawned with an &, does the parent process here wait for the child processes (the zombie processes)exit status even without using wait()?
mera window system hai cmd run nhi ho rhaa hai ??
Does Multiprogramming depend on ssd/hdd speed??
i think depend on ssd
Sir what will be command for windows operating system? for trying the hands on
Thank you sir
Commenting for better reach of the video
bhaiya orphan or zombie process ko khud se practically krk dekhna chate h but bash script create kaese kare?
Present Bhaiya
💥💥💥
18:18 babbar bhai ko kyu toda 🤣🤣
nice explanation

sir swapping me process swapped space me jata h ,but i want to ask that jo process swapped area me move ho rhi h wo kaha se hoti h,ready queue se direct swapped space ya phir cpu me jaane k bad swapped space me jaati h .
cpu ke through jata hai
