What do you understand about system calls? |
|
Answer» A system call is a way for a computer programme to REQUEST a service from the kernel of the operating system it is EXECUTING on. A system call is a program's way of interacting with the operating system. A system call is when a piece of software makes a request to the operating system's kernel. The Application Program Interface (API) is USED to provide services from the operating system to user programmes (API). It serves as a link between a process and the operating system, allowing user-level programmes to request services from the operating system. System calls are the sole way to GET into the kernel system. Any software that consumes resources must make USE of system calls. |
