The kernel manages a computer’s hardware and software interactions, serving as the critical bridge between applications and the physical components of a computer. It is responsible for overseeing and coordinating all hardware resources, which includes tasks such as memory management, process control, and system calls.

Memory management ensures that each application and process has the necessary memory allocated to it while protecting the memory space from unauthorized access by other processes. This involves managing both the physical memory (RAM) and virtual memory efficiently.

Process control is another vital function of the kernel, where it manages the execution of processes. This includes creating and terminating processes, scheduling them for execution on the CPU, and providing inter-process communication mechanisms. The kernel ensures that processes do not interfere with each other and run in a secure and stable environment.

System calls are the interfaces through which user applications request services from the kernel. They act as the gateway for applications to interact with hardware resources, such as reading or writing files and communicating over networks.

Every modern operating system (OS)—such as Windows, Linux, or macOS—relies on its kernel to ensure stable and efficient operation. The design and implementation of the kernel can significantly influence the overall performance and security of the operating system, making it a fundamental aspect of computer architecture. The kernel thus plays a crucial role in facilitating resource management, ensuring efficient system performance, and providing a reliable platform for applications to run effectively.
