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.

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?

My question is why not run process always in kernel mode there's no need to make so many system calls .
@jayenb4848
5 жыл бұрын
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.
