So, when a child process is completed, it informs it's parent by a system call and returns the status. However, apart from normal termination, there might be few other reasons for process termination such as child process has started exceeding the resources being allocated by parent, it's no longer required by parent or the parent process itself has terminated.
Omg I'm laughing so hard I am literally in tears. All this talk of parents terminating their children once they have "served their purpose and are no longer needed" hahahaha oh I can't. I just can't. It's so funny.
there are some cases, like the child process can run as a Deamon process when the parent process was terminated after it serves. in this special case though the parent task terminated by the OS, but a child process still in alive as a background task. Reference book: Mastering Embedded Linux programming 2nd edition by Chris Simmonds. section 12, topic - Deamon at 7:37, it is contradicting with a above book explanation.
A process terminates when the execution of its last statement finishes and asks the OS to delete it via an exit system call. It will return its status value (an integer) to its parent via a wait system call. It's necessary for the parent to control the statuses of its children All of its resources will be deallocated (memory, I/O buffers, open files...) There are other circumstances where a process is terminated: - A process can cause the termination of other processes (only the parent can kill its own children) via an appropriate system call - User can terminate a process manually Reasons why the parent process kills their children: - The children process exceed the resources allocated to them (the parent should have mechanism to inspect this info) - The task assigned to the children process is no longer required - The children processes will be terminated if their parent is terminating (decided by some OS)
the only thing that I find a little difficult is visualizing how these fundamentals are applied when navigating through the operating system, I understand everything that you said but, how I would use these fundamentals, is necessary to solve some sort of problem or something like that?
Parent can kill the children and no other can kill children parent can kill children for some resources and the resources were give to other children .if parent is terminated then child also terminated simply it says that termination of parent can stop tha loop and perform .......is i am right?
i like how you clarified the sentence "the parents will kill the children" by saying "in terms of processes"
wow. this was pretty dark.
"Parent might kill its child if it uses too much resources."

A child becomes orphan if parent terminated (without invoking wait() )
I like the fact that topics that look too complicated and high-leveled turn out to be useful and simple even for beginners.
best teacher on youtube
5:36 the moment he said : first reason that a parent might kill its children in terms of process 😂 😂 that was hilarious ! Btw . Great Explanation 🙌♥️
yosh
Goodness, half way through this series and you are an absolute life saver. Soo much better than my professor. You're awesome!
Child: misbehaves
Parent: *die*
Child: done washing dishes
Parent: *diE*
Child: am still hungry
Parent: *DIE*
Never thought that a random o.s. topic will hit me personally.
Brooo🤡😂

And also if parent terminates then you also have to go

superb explanation keep it up
Thank god for these videos, you're doing an amazing job!
Amazing As Always Neso Academy.♥️♥️♥️♥️♥️
But Through Out Lecture I Was Imagining .... 😂 You Know... 😂
We all don't know what's really going on inside. Maybe we've to really start programming an OS from Scratch ourselves 🤣🤣
Clear cut explanation....thanks
A process terminates when the execution of its last statement finishes and asks the OS to delete it via an exit system call.
It will return its status value (an integer) to its parent via a wait system call. It's necessary for the parent to control the statuses of its children
All of its resources will be deallocated (memory, I/O buffers, open files...)
There are other circumstances where a process is terminated:
- A process can cause the termination of other processes (only the parent can kill its own children) via an appropriate system call
- User can terminate a process manually
Reasons why the parent process kills their children:
- The children process exceed the resources allocated to them (the parent should have mechanism to inspect this info)
- The task assigned to the children process is no longer required
- The children processes will be terminated if their parent is terminating (decided by some OS)
Thank you Neso Academy
i lost it at @4:55 to the end of the video 😂 😂😂 😂😂 😂😂 😂😂 😂
glad that my parents didnt watch this, else i would have been terminated lol
WTF, you are already terminated by Hashirama senju 😶 😑
😂

Hahaha
very well explained ...
just wow! ❤✨
Explanation is very good.
You are amazing !! please keep going
Ek number 👍
At 5:36, it was getting too dark all of a sudden ... until you said 'in terms of process' 😅
Thank you so much sir
Nyyccccccc explanation ❤️❤️❤️❤️
Thank you
I love these videos :D
gd one as always
Book to refer which is in sync with the lectures - OS by Abraham Silberschatz
Thanks ☺️...
Thankyou sir
Awesome 👍
Nice sir
Sir can u explain the process preemption and process blocking
the only thing that I find a little difficult is visualizing how these fundamentals are applied when navigating through the operating system, I understand everything that you said but, how I would use these fundamentals, is necessary to solve some sort of problem or something like that?
How can the parent process know if the child has exceeded its resource usage in a single processor environment?
Remembering those days when I use to play video games for 1 hr daily limit 🤣🤣🤣
Gaming task was allocated for 1hr if exceeds, then rest of history....
Filicide is predominant in OS. LOL. There should be an OS police to control filicide.
thanks for expanding my vocab
Most of lines (written)used in your video are actually same as written in my university textbook.
99% same lines😳
what books or any specific resources....
7:56 something is fishy
Shit turned dark real quick
What’s the drawback of ‘Process Termination’ in deadlock? And in which method of deadlock handling does it belong?
no children were harmed in this video
Can someone please tell me how to create a child in real life also? 🤔 🤔 I also want to create my child😍
*Luckily humans are not operating systems*
r e yaar mummy papa samne batha tha mere, e sunne k bad mummy mere taraf dekhi.............kya padh raha beta????
This can go very out of context
It's cruel.
"Only parent can kill its own children" , it makes sense haha
Wow I wanted to study operating system not return my trauma 🙂 😳
ok
Imagine being born as a child of a process 💀
Parent can kill the children and no other can kill children parent can kill children for some resources and the resources were give to other children .if parent is terminated then child also terminated simply it says that termination of parent can stop tha loop and perform
.......is i am right?
