Answer:
To access the services of OS the interface is provided by System calls
Explanation:
“System call acts as a bridge between the user and the operating system”. Whenever the user place the request to execute a process, a system call is generated to interact with the Kernel of the operating system and OS executes and returns the result to the user.
There are 5 different system calls in OS. They are Process control, File management, Device management, Information maintenance and communication.
Eg. of System calls: CreateProcess(), WriteFile(), ReadConsole(), etc.
