An operating system is a complex software infrastructure designed to provide an abstract set of interfaces and services for use by application processes (Franklin & Coustan‚ 2000; Silberschatz‚ Galvin‚ & Gagne‚ 2009; Tanenbaum‚ 2008). The operating system manages the execution of these processes and controls their access to these interfaces and services. Understanding how an operating system accomplishes this can best be achieved through examination of the major elements and technologies comprising
