How kernal work in operating system?..

Answer / Syed Abdul Nadeem

The kernel is the core component of an operating system (OS) that manages and controls system resources, such as memory, CPU, I/O devices, and files. It acts as a mediator between user applications and hardware. Key responsibilities of the kernel include:

1. Process management: Scheduling, creating, and terminating processes, and allocating CPU time to them.
2. Memory management: Managing physical memory (RAM) by dividing it into smaller chunks for efficient allocation to processes.
3. Device drivers: Providing a standard interface between user applications and hardware devices through device drivers.
4. File system management: Handling file creation, deletion, and access by user applications.
5. Interprocess communication (IPC): Facilitating communication between different processes running in the operating system.
