What is a system call?

A  system  call  is  a  request  made  through  any  program  to  the  operating  system  for performing tasks, picked by a predefined set, that the said program doesn't have needed  permissions  to  execute  into  its  individual  flow  of  execution. System calls give the interface between the operating system and a process. Most operations interacting along with the system need permissions not available to a user level process, for example: input and output performed with a device present in the system or any form of communication along with other processes needs the use of system calls.
