Mach (kernel): History, Overview & Software based on Mach

Mach (/mɑːk/) is an operating system kernel developed at Carnegie Mellon University by Richard Rashid and Avie Tevanian to support operating system research, primarily distributed and parallel computing. Mach is often considered one of the earliest examples of a microkernel. Nonetheless, not all versions of Mach are microkernels. Mach's derivatives are…
