Types of system calls: Process Control: These system calls are used to create, modify, and manage processes and threads, including functions such as fork(), exec(), wait(), and exit(). File Management: These system calls are used to create, modify, and manage files and directories, including functions such as open(), read(), write(), and close(). Device Management: These system calls are used to access and manage hardware devices such as printers, disks, and network interfaces, including functions such as ioctl() and read(). Information Maintenance: These system calls are used to retrieve and update information about the system and its resources, including functions such as getpid(), getuid(), and getgid(). Communication: These system calls are used to facilitate interprocess communication and synchronization, including functions such as pipe(), socket(), and sendmsg(). Memory Management: These system calls are used to allocate and manage memory resources, including functions such as mmap(), malloc(), and brk().
Great job. This lecture explains five major types of system calls i.e process control, file manipulation, device management, information maintenance, communication. However each type is well explained by citing appropriate examples under each.
good illustration five stratification for system calls. videlicet 1. process control 2.file manipulation 3.device management 4.info maintenance 5.communication
hello sir, thanks a lot for providing free and informative knowledge to everyone, but in this lecture about types of system call, I noticed that in the OS concept textbook I read, there are 6 types of system call, including protection. I hope you acknowledge my opinion, thank you very much!!
Hey, great video! I just have one question. Can device manipulation system calls for logical attach/detach of devices be used for remote devices also or should communications system calls be used?
what's the difference between types of system calls he describes in this video and subsystems of the linux kernel ? (Process management PP, Virtual File System VFS, Memory Management MM, Network Stack, Device Driver DD) ? Are these related ?
hey NESO 9:03 , if a programm is running for example a video is played in gallery . and then i opened the same video from gallery to another video player application . is this the example of communication call ?
What are wait event and signal event under process control? Can someone plz explain all those "reposition"s that he mentioned? What is being done here? Also, if I am modifying a file which system calls are used?
If the process somehow crashes in the kernel mode, the whole system crashes. Hence the program is run in user mode, and a system call is made whenever required.

Do u study at iit? Or aiming for iit?
Superrr
Can you share all notes of os?

such a good lecture series on the RUclips
Great Job! your explanation is very clear and concise. Thanks a lot.
I cannot get enough of your videos Sir. Thank you so much (y)
Thanks! System calls:
1. Process control
2. File manipulation
3. Device management
4. Information maintenance
5. Communication
Great Work! Well explained!Please share the notes also.
Thank You
sir.. I am polytechnic Student.. sir pls make a video in computer security.. great video thanks alot
Great job
You are the best teacher ❤🎉
Hey, great video! I just have one question. Can device manipulation system calls for logical attach/detach of devices be used for remote devices also or should communications system calls be used?
Thanks a lot for the great creations 👍👍🙏
Thanks teacher, I'm learning a lot with you :D

Sir plz upload videos bit faster on os...ur videos helping me alot sir...great work sir
well-explained .
Thanks a lot !
Thanks for the knowledge
very helpful video.
thank, you so much🙏
Should have given examples rather than screen reading
I think this because he made it to be a short-time video, but for deep knowledge and examples search is really needed
love and respect
Sir please upload videos bit faster on OS
These videos are really helpful
We also have protection system call because we study six major categories
There are service's of system calls......
Thanks
the 6th Type is Protection.....
you are amazing
But very helpful video 🙏
Sir, Process means when the program was executing, So in Process control why we use load and execute sys calls.
Sir please upload a video on types of operating system...?
thank you
thank you sir!
thanx so much. I wud love 2 know; what is the meanx of REPOSITION?
I request you can make more videos for operating system
Thanks a lot
hey NESO 9:03 , if a programm is running for example a video is played in gallery . and then i opened the same video from gallery to another video player application . is this the example of communication call ?
No bro I don't think so because it's not accessing the process it is just reffering it ..
What are wait event and signal event under process control?
Can someone plz explain all those "reposition"s that he mentioned? What is being done here?
Also, if I am modifying a file which system calls are used?
I have questions about semaphore and mutex, can have a video on these topics? Thank a lot
Thankyou sir
is there any kernel level programing tutorial ?
Sir pls make more lectures for electronics and communication..great videos ..
Respect...❤💯👏🙏
8:38 what does "system data" refer to ?
calendar data and other default applications of os
can we do any task without any system call?
sir please make a video on thread,s.....
What do you mean by getting and setting system data 8:25
Where is the previous video?
what is parent and child process?
Processes can create another process. Creating process is called parent process and created process is called child of that process
I will buy you guys a microphone, where's yalls venmo?
My question is why not run process always in kernel mode there's no need to make so many system calls .
If the process somehow crashes in the kernel mode, the whole system crashes.
Hence the program is run in user mode, and a system call is made whenever required.
Sao here
System call have 6 type!
very gddd
🙏
6 type is pretection..
Sir please upload videos bit faster on OS ！！！！！！！！！！！thank you！^^
🎉🎉🎉🎉🎉🎉❤❤❤❤❤
