It acts as a bridge between applications and the physical hardware of the computer. The kernel is responsible for critical tasks like process management , memory management , device management , and system calls . It ensures that different applications get their required share of CPU time, memory, and access to devices without interfering with each other. By controlling how hardware and software interact, the kernel provides an efficient and stable environment for the operating system to run multiple processes simultaneously. a) File System: The file system is a component of the operating system that is responsible for managing and organizing data on storage devices.
