Advantages of system calls
The system call is a technique of calling the system in such a way that computer program requests a service from the kernel of the operating system. The system can only provide the services if we call the system with a system call.
There is two kind of modes. The first one is kernel mode and another is user mode. The user can only get the services from the OS and user is able to send the commands to the kernel mode. User from the user mode sends systems calls to the kernel mode.
