Define System Calls With Example


System Calls : A system call in an OS is a process that provides a lito between the operating system and a running process. Requirement for example: Whenever any process is running in the system, and if the process requires some print to be executed by the operating system, then at that time the process is abandoned and a statement has to be called. Only those that can interact with the journal perform the necessary actions. And this special type of function is known as System Call in the Operating System. That is why it is known that system calls in the OS provide a partnership so that the running processes can communicate with the operating system. System connections are the main entry points to the system in the OS.
