1.0 BASIC CONCEPTS 1.1 What is a Process? In computing‚ a process is an instance of a computer program that is being executed. It contains the program code and its current activity. Depending on the operating system (OSf a process may be made up of multiple threads of execution that execute instructions concurrently (Robbins‚ Kay. A. and Steven Robbins‚ 1996). A computer program is a passive collection of instructions; a process is the actual execution of those instructions. Several processes

Coordinating the Machine’s Activities One of the most fundamental concepts of modern operating systems is the distinction between a program and the activity of executing a program. The former is a static set of directions‚ whereas the latter is a dynamic activity whose properties change as time progresses. The activity of executing a program under the control of the operating system is known as a process. Associated with a process is the current status of the activity‚ called the process state

INTRODUCTION 1. WHAT IS PROCESS SCHEDULING? To manage all the processes in ready queue for the maximum utilization of CPU‚ this job is done by process scheduler on the basis of scheduling algorithms. Scheduling is a key concept in computer multitasking‚ multiprocessing operating system and real-time operating system designs. Scheduling refers to the way processes are assigned to run on the available CPUs‚ since there are typically many more processes running than there are available CPUs. This

Why) to Stop Multitasking and In Defense of Multitasking but give the reader something to think about. One presents an argument against multitasking while the other defends it. The two authors have different‚ and distinctive‚ writing styles. They also provide varying amounts of support for their argument. With these differences‚ the only similarity seems to be what the essays discuss. In the first essay‚ How (and Why) to Stop Multitasking‚ the author presents a case against multitasking. The author

Here are some perspectives from Coach Bill Patton: An understanding of how men and women differ in learning style and brain function enhanced my coaching methods. Both men and women multitask but it is something I noticed they approach differently. Although‚ multitasking may seem like a good idea‚ studies now show that it often leaves us less present and too quickly moving on
