A System call is a programmatic approach in which the computer program sends the request a service to the kernal. The name of a system call in the Linux system is syscalls().
Explanation:
- A system call is used to interact with the operating system.
- System calls are made by an application program when it wants to access a resource or services which are not under its access.
- Since Application cannot make direct system call so it is done through an Application Programming Interface Known as the API
- API is much easier to use compared to the system calls.
- System calls are also known as the Kernel calls in the Linux System.
- Types of System calls are 'Process control', 'File management', 'Device management', and 'Information Management'.
