One of the kernel's classes is the microkernel. Because it is a kernel, it is in charge of all system resources. In a microkernel, however, user and kernel services are implemented in separate address zones. Because user services are PLACED in user address SPACE and kernel services are located in kernel address space, the kernel and operating system are both smaller. It just offers the MINIMAL essentials in terms of process and memory management. The execution microkernel is slowed by message forwarding, which is used to establish communication between client programs/applications and services executing in user address space. Because user and kernel services are separated, the Operating System is unaffected if one fails. As a result, one of the microkernel's advantages is enhanced. It's simple to extend since new services are added to the user address space rather than the kernel address area, requiring no kernel changes. It's also portable, secure, and dependable. The architecture of a microkernel is SHOWN below:

The following are some of Microkernel's advantages:

• This kernel performs better because of its compact and isolated architecture.
• The system can be expanded more easily since it can be added to the system application without DISRUPTING the kernel.
