Course Overview

A distributed operating system is a software over a collection of independent, networked, communicating, and physically separate computational nodes. Each individual nodes hold a specific software subset of the global aggregate operating system. Each subset is a composite of two distinct service provisioners. The first is a ubiquitous minimal kernel, or micro-kernel, that directly controls that node’s hardware. Second is a higher-level collection of system management components that coordinate the node’s individual and collaborative activities. These components abstract micro-kernel functions and support user applications.
