The various roles of an operating system generally revolve around the idea of "sharing nicely." An operating system manages resources, and these resources are often shared in one way or another among the various programs that want to use them: multiple programs executing concurrently share the use of main memory; they take turns using the CPU; and they compete for an opportunity to use input … Operating systems that support a form of process management is considered to be a multitasking operating system. Representation. In order to manage a process, an operating system designer needs to determine how to best represent a process given OS design criteria and required system resources. A process consists of the following:
Operating Systems II Steven Hand Michaelmas Term 2005 8 lectures for CST IB Operating Systems II P/L/TT/11. Course Aims This course aims to: impart a detailed understanding of the algorithms and techniques used within operating systems, consolidate the knowledge learned in earlier courses, and help students appreciate the trade-o s involved in designing and implementing an operating system. Why … Memory management techniques Single contiguous allocation. Single allocation is the simplest memory management technique. All the computer's memory, usually with the exception of a small portion reserved for the operating system, is available to the single application.
