A Hybrid Kernel is a type of operating system kernel that combines features of both monolithic kernels and microkernels. It aims to provide the performance benefits of a monolithic kernel, which runs most services in kernel space, while also incorporating the modularity and flexibility of a microkernel, which runs services in user space. This design allows for better resource management and easier updates. In a hybrid kernel, essential services like device drivers and file systems can operate in kernel space for efficiency, while less critical services can run in user space. Examples of operating systems that use a hybrid kernel include Windows and macOS. This approach helps balance speed and stability, making it suitable for a wide range of applications.
