Mikrokernelarkkitehtuurin

Mikrokernelarkkitehtuuri is a type of operating system architecture that emphasizes minimalism and modularity. In this design, the kernel contains only the most essential components, such as inter-process communication (IPC), basic scheduling, and low-level hardware abstraction. Non-essential services, like file systems, device drivers, and network protocols, are implemented as user-space processes or servers. This separation of concerns enhances system stability and security, as a fault in a user-space service does not directly affect the kernel. Additionally, the modular nature of a microkernel allows for easier updates and customization, as individual components can be modified or replaced without disrupting the entire system. However, the performance overhead of IPC and the increased complexity of managing multiple user-space processes are potential drawbacks of this architecture. Despite these challenges, the microkernel approach has been successfully implemented in various operating systems, including QNX, Minix, and the L4 microkernel family.
