What is the role of the Linux kernel, and how does it differ from the Windows kernel?

The kernel is a fundamental component of any operating system that provides low-level services and manages hardware resources. The Linux kernel, which was initially created by Linus Torvalds in 1991, is the core of the Linux operating system and is responsible for managing memory, processes, and drivers.

The Windows kernel, on the other hand, is the core of the Windows operating system and provides similar services. However, it differs from the Linux kernel in several ways. For example, the Windows kernel is not open-source, meaning that its source code is not publicly available. Additionally, the Windows kernel is monolithic, meaning that it includes all core services and device drivers in a single executable file.

On the other hand, the Linux kernel is open-source, which means that its source code is available to anyone who wants to modify or improve it. Furthermore, the Linux kernel is modular, which means that its core services are separated into individual modules that can be loaded and unloaded as needed. This allows users to customize the kernel to suit their specific needs and results in a more efficient and flexible system.
