Operating system (OS) internals refers to the inner workings of an operating system. It encompasses the components and mechanisms that make up an OS, including process management, memory management, file systems, I/O management, security and protection, networking, virtualization, and performance analysis. Understanding OS internals is essential for anyone involved in developing or administering operating systems, as it provides a deeper understanding of how they work and how they can be optimized for performance and security.
