This blog post examines various operating system architectures in detail. The key differences and advantages between monolithic, microkernel, and hybrid architectures are discussed. The single-kernel architecture of monolithic systems, the modular approach of microkernels, and the features of hybrid systems that combine these two architectures are explained. The performance comparison of these architectures is also presented, highlighting methods for improving the performance of monolithic systems and the microkernel development process. The post also evaluates the future of hybrid architectures, current trends, and innovations in operating systems. Finally, it provides readers with a comprehensive overview of operating system architectures. Introduction to Operating System Architectures An operating system (OS) is the fundamental software that manages the interaction between a computer system's hardware and its users.
