TAILIEUCHUNG - Lecture Operating system concepts (Sixth ed) - Chapter 4: Processes

Chapter 4 - Processes, now includes coverage of multitasking in mobile operating systems, support for the multiprocess model in Google’s Chrome web browser, and zombie and orphan processes in UNIX. The objectives of this chapter are to introduce the notion of a process a program in execution, which forms the basis of all computation; to describe the various features of processes, including scheduling, creation, and termination; to explore interprocess communication using shared memory and mes- sage passing. | Chapter 4 Processes Process Concept Process Scheduling Operations on Processes Cooperating Processes Interprocess Communication Communication in Client-Server Systems Operating System Concepts Silberschatz Galvin and Gagne 2002 Process Concept An operating system executes a variety of programs Batch system - jobs Time-shared systems - user programs or tasks Textbook uses the terms job and process almost interchangeably. Process - a program in execution process execution must progress in sequential fashion. A process includes program counter stack data section Operating System Concepts Silberschatz Galvin and Gagne 2002 Operating System Concepts Process Control Block PCB Information associated with each process.
