Ipc microkernel
Web31 jan. 2024 · A microkernel is a software or code which contains the required minimum amount of functions, data, and features to implement an operating system. In Monolithic Kernel approach, the entire operating system runs as a single program in kernel mode. A Microkernel is the most important part for correct implementation of an operating system. Web18 jun. 2024 · In the monolithic system, the service is obtained by a single system call, which requires two mode switches (changes of the processor’s ring or CPU mode). In the microkernel-based system, the service is obtained by sending an IPC message to a server, and obtaining the result in another IPC message from the server.
