Much more code is required to write a microkernel than the monolithic kernel. … WebSome examples of operating systems that use monolithic kernels are Dos, Solaris, AIX, Linux, OpenVMS, etc. A monolithic kernel suits minute tasks such as CPU scheduling, system calls, etc. This is so because it manages limited resources.

WebA real-time operating system (RTOS) is an operating system with two key features: predictability and determinism. In an RTOS, repeated tasks are performed within a tight time boundary, while in a general-purpose operating system, this is not necessarily so. Predictability and determinism, in this case, go hand in hand: We know how long a task ... WebModular operating systems such as OS-9 and most modern monolithic operating systems such as OpenVMS, Linux, BSD, SunOS, AIX, and MULTICS can dynamically load (and unload) executable modules at runtime. This modularity of the operating system is at the binary (image) level and not at the architecture level.

WebA microkernel RTOS is structured with a tiny kernel that provides minimal services. The microkernel works with a team of optional cooperating processes that run outside the kernel space (in the user space), which provides higher-level OS functionality. The microkernel itself lacks file systems and many other services normally expected of an OS.
