System Calls in Operating System in Hindi | #14

Описание: In an operating system (OS), a system call is a request made by a program to the OS kernel for a specific service or action to be performed. System calls provide an interface between the program and the kernel, allowing the program to request access to resources and services that are managed by the kernel, such as input/output operations, memory allocation, and process control.

System calls are typically made using a special function or instruction that is recognized by the kernel. When a program makes a system call, it is interrupted by the kernel and the request is passed to the kernel for processing. The kernel then performs the requested action and returns control to the program, usually with a return value indicating the success or failure of the system call.

System calls are a key component of the operating system, as they allow programs to request services and resources from the kernel in a standardized way. This makes it possible for programs to run on a wide range of hardware and software platforms, as long as the operating system provides the necessary system calls.
