In computing, the 'kernel' is the central component of most computer operating systems. Its responsibilities include managing the system's resources (the communication between hardware and software co...

Operating System Structure; Monolithic kernels (the \big mess" according to Tanenbaum) led to interest in more structured operating systems, such as layering and better structuring. Layered operating system example is Xinu|\a small, Look at excerpts from \Microkernel Operating System Architecture and Mach" paper;

Besides managing complexity, the structure of the operating system can influence key features such as robustness or efficiency: ... The communication overhead inside the microkernel operating system can be higher than the communication overhead inside other software, however, research has shown this overhead to be manageable.

Thus, a general purpose of the present invention is to provide an efficient operating system structure that permits scaling from small, embedded systems type operating systems to relatively fully featured, network capable, standards compliant operating systems.

In this paper we evaluate the memory system behavior of two distinctly different implementations of the UNIX operating system: DEC's Ultrix, a monolithic system, and Mach 3.0 with CMU's UNIX server, a microkernel-based system.

An error that occurs in a microkernel operating system service can potentially result in state corruption and ser-vice failure.
