Answer / Sarvesh Kumar Satyarthi
A system call is a request made by a program to the operating system for services that the program cannot provide itself. It allows programs to access hardware, manage processes, interact with the file system, and perform various other tasks.nnWhen a system call is invoked, the control flow of the program temporarily transfers from user mode (where the program runs) to kernel mode (where the operating system manages resources). Once the system call has been processed, control returns to the program.
