Describe microkernel operating system
WebMar 20, 2024 · Microkernel A microkernel is a kernel that contains only the essential components required for the basic functioning of the operating system. All other components are removed from the kernel and implemented as user-space processes. The microkernel approach provides better modularity, flexibility, and extensibility. In computer science, a microkernel (often abbreviated as μ-kernel) is the near-minimum amount of software that can provide the mechanisms needed to implement an operating system (OS). These mechanisms include low-level address space management, thread management, and inter-process communication (IPC).

WebFeb 19, 2024 · Microkernel Architecture. The basic ideology in this architecture is to keep the kernel as small as possible. We know that kernel is the core part of the operating system and hence it should be meant for handling the most important services only. In microkernel architecture, only the most important services are put inside the kernel and … WebMicrokernel-based hypervisors are also well suited to secure I/O virtualization: instead of the typical monolithic approach of placing device drivers into the hypervisor itself or into a special-purpose Linux guest operating system (the Dom0 method described earlier), the microkernel-based hypervisor uses small, reduced-privilege, native ...
WebNov 11, 2024 · The Kernel is responsible for low-level tasks such as disk management, memory management, task management, etc. It provides an interface between the user and the hardware components of the system. When a process makes a request to the Kernel, then it is called System Call.
