what is system call?
these are tiny programs which are attached with the operating system which are call automatically by the call of some specific processes.
These are type routines which are called via process itself.
For example suppose we have to give the copy command then it will automatically check the below informations
1. Is the source file is exist.
2. is there any content present in the source file.
3. Checking the destination file.
4. Is there enough space for copy.
5. is the content is rewritable or non-movable.

Or in other words - a system call is like a normal function call, but to the kernel of the operating system. Therefore, a system call is executed with more privileges. System calls are the basic set of function that an operating system provides to user application. They are like an interface to software.
