* System Call :
The system call provides an interface to the operating system services.
Application developers often do not have direct access to the system calls, but can access them through an application programming interface (API). The functions that are included in the API invoke the actual system calls. By using the API, certain benefits can be gained.
PORTABILITY : as long a system supports an API, any program using that API can compile and run.
EASE OF USE: using the API can be significantly easier then using the actual system call.
*TYPES OF SYSTEM CALLS:
1. Process Control
2. File Management
3. Device Management
4. Information Management
5. Communication
