The kernel is the central component of an operating system that manages computer and hardware operations.  Types of Kernel:   Monolithic Kernel: It is a type of kernel in which all operating system services run in kernel space. It is dependent on the components of the system.  Micro Kernel: Kernel types take a minimalist approach. It has virtual memory and thread scheduling capabilities.  Hybrid Kernel: It is a hybrid of a monolithic kernel and a microkernel. It combines the speed and design of a monolithic kernel with the modularity and stability of a microkernel.  Exo Kernel: It is the type of kernel that adheres to the end-to-end principle. It employs as few hardware abstractions as possible. It allots physical resources to various applications.  Nano Kernel: It is a kernel that provides hardware abstraction but no system services. Because the Micro Kernel lacks system services, the Micro Kernel and Nano Kernel have become analogous.
