The Mach operating system was designed to incorporate the many recent innovations in operating system research to produce a technically advanced and fully functional system. Mach incorporates multiprocessing support throughout which is extremely flexible and ranges from shared memory systems to systems with no memory shared between processors. Mach is an operating system kernel developed at Carnegie-Mellon University to support operating system research, primarily distributed and parallel computation. The project at CMU ran from 1985 to 1994. …showed first 75 words of 397 total…

Mach ensures that an application cannot write on another application's memory or on the operating system's memory. 2.Preemptive multitasking. In a modern operating system, the processes share the CPU efficiently. 3.Advanced virtual memory. Mach maintains address maps that control the translation of a task's virtual addresses into physical memory. 4.Real-time support. This feature guarantees low-latency access to processor resources for time-sensitive media applications.
