[@Mehraj_IITKGP]

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().

Do u study at iit? Or aiming for iit?

[@mugadaashok6473]

Superrr

[@quratraja7391]

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.

[@amishachourpagar9925]

I love neso academy so much.
Thank you 😀❤️❤️❤️

[@velasqjo]

Great Job! your explanation is very clear and concise. Thanks a lot.

[@saadmanahmed860]

good illustration
five stratification for system calls. videlicet
1. process control
2.file manipulation
3.device management
4.info maintenance
5.communication

Great job

[@mazharkhaliq1971]

Thanks for the knowledge

[@kanimozhin8177]

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?

[@antonio-vr4iu]

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 ?

[@PRABHJOTKAUR-du1jd]

Thanks

[@ayushiyadav1]

[@minhnguyenquang4448]

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!!

you are amazing

[@dushananuradha1098]

Respect...❤💯👏🙏

[@ani9899]

Sir pls make more lectures for electronics and communication..great videos ..

[@varaprasadgrandhi8101]

Sir, Process means when the program was executing, So in Process control why we use load and execute sys calls.

[@UmerMansoor-ns1yl]

is there any kernel level programing tutorial ?

[@mukhtiarahmad7448]

sir please make a video on thread,s.....

[@RasulyDevelopment]

the 6th Type is Protection.....

[@DallasCowboyFan95]

What do you mean by getting and setting system data 8:25

[@nowshintabassum2768]

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?

[@trilecao9014]

Thanks! System calls:
1. Process control
2. File manipulation
3. Device management
4. Information maintenance
5. Communication

[@aqeelkirmani7391]

Should have given examples rather than screen reading

[@SkyV77]

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 ?

[@saishekhar5847]

can we do any task without any system call?

[@MaxCoplan]

Where is the previous video?

[@user-em9mw9ch3y]

8:38 what does "system data" refer to ?

[@boomshakalaka5066]

calendar data and other default applications of os

[@khadijehemad5345]

We also have protection system call because we study six major categories

[@lakshmisayyapureddy376]

There are service's of system calls......

[@veganphilosopher1975]

I will buy you guys a microphone, where's yalls venmo?

[@aboutknowledge2474]

very gddd

[@absobel]

Sao here

[@sonalagarwal9297]

what is parent and child process?

[@nidhinhari8397]

Processes can create another process. Creating process is called parent process and created process is called child of that process

[@voonlin4678]

System call have 6 type!

[@TheFinestStuff]

🙏

[@umairalvi7382]

My question is why not run process always in kernel mode there's no need to make so many system calls .

[@jayenb4848]

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.

[@user-ny5yx2hr3r]

Sir please upload videos bit faster on OS ！！！！！！！！！！！thank you！^^
