Operating system concepts –10th edition 3.4 silberschatz, galvin and gagne ©2018 3.1 process concept an operating system executes a variety of programs that run as a process. process –a program in execution; process execution must progress in sequential fashion. no parallel execution of instructions of a single process multiple parts.

Chapter 3 Operating System Structures Identify the values of pid at lines a,b,c, and d. (assume that the actual pids of the parent and child are 2600 and 2603, respectively) at line a it will print "child : pid = 0" (value returned by fork to child) at line b it will print "child : pid1 = 2603" (actual pid of child) at line c it will print "child : pid = 2603" (value returned by. Terms in this set (17) process. a program that is being executed; unit of work in a modern time sharing system. processes that make up a system. operating systems processes executing system code and user processes executing user code. what is the benefit of switching the cpu between processes. doing so makes the computer more productive. Study with quizlet and memorize flashcards containing terms like a process control block . select one: a. stores the address of the next instruction to be processed by a different process b. is an example of a process queue c. determines which process is to be executed next d. includes information on the process's state, the list of processes waiting for a particular i o device is called a. Two different processes: the text section are equivalent, the data, heap and stack vary. process can be an execution environment for other code. ( simulation) e.g. 1. java testprogram. the command java runs the jvm as an ordinary process, then executes the java program testprogram in the vm.

Processes may create other processes through appropriate system calls, such as fork or spawn. the process which does the creating is termed the parent of the other process, which is termed its child. each process is given an integer identifier, termed its process identifier, or pid. the parent pid ( ppid ) is also stored for each process.
