What is the function of a kernel in an operating system?

The function of a kernel in an operating system is essential for the overall performance and management of the computer. It acts as a bridge between the software applications and the hardware of the computer. Specifically, the kernel is responsible for managing system resources such as the CPU, memory, and input/output devices. It ensures that these resources are allocated efficiently among different running processes and that they can communicate with the hardware effectively.

By managing operations, the kernel handles tasks such as process scheduling, memory management, and device management. This core functionality makes it a fundamental component of any operating system, enabling it to run applications smoothly while making optimal use of available hardware resources. The emphasis on resource management and coordination underscores its critical role in the performance and stability of the system.
