What is the purpose of process management in operating systems?

I think the question was about processes running on an OS, not software development process.\n\nThe biggest reason is multitasking.  A single process often does not use the full capability of the computer, as it may be waiting for something to complete, generally some kind of IO (e.g. disk or user input).  Multitasking allows the CPU to work on something else while that is occuring.\n\nOnce you decide to have multiple processes, you need some way to manage them, keeping one process from mucking up another process.

They basic function of the windows operating system is just to provide you with a Graphical User Interface for operating your PC.  Which translates to a very user friendly way to work your pc.  Back in the day before windows you had only DOS and the easier way was using utils like HD manager, which just provided a graphical shortcut to your programs.

Processes are given a process priority, let's say from 0 (lowest) to 15 (highest). The process scheduler queues all processes according to their priority in their appropriate queue.\nThe scheduler start up with the first ready process of the highest priority queue. A process becomes ready by hardware interrupt, by time interrupt or by request (software interrupt).\nEvery process must be interruptable either by itself (waiting for an event) or by time (by the scheduler). Therefore is guaranteed that also processes with a low priority will be executed.

An operating system is a special computer program that manages the relationship between application software, the wide variety of hardware that makes up a computer system, and the user of the system.\n\nThe lowest level of any operating system is its kernel, the first layer of software loaded into computer memory when it starts up . As the first software layer, all other software that gets loaded after it depends on this kernel to provide them with various common core services. These services include, but are not limited to: disk access, memory management, task scheduling, and access to other computer hardware|hardware devices.\n\nThere are many types of operation systems, but Unix and Windows variants are the main types found on personal computers. \n\nSee the link below for more data.

There are all used as batch scripts and user inputs. Portability and user preferences is the reason people choose different ones.\n\nsh, csh, ksh\nash, bash

try using Process Explorer located on www.sysinternals.com.  It's a free stand-alone utility that acts like task manager but more powerful.  You may see the program running this way

The most common modern computers consist of processors, memories, timers, disk or tape drives, terminals, and wide variety of other devices. Operating systems manage these hardware devices and resources, and provide controlled access to these devices for the user programs [Tan92]. The rapid growth in technology allows us to have faster hardware devices than past generations; however, not every type of device has increased its speed at the same rate. For example, disk drives have improved in speed of access, but due to the mechanical limit in rotation, the overall speed increase is not as significant as processors or other devices [RR96]. The fundamental difference between mechanical devices and semiconductor materials causes this disparity in performance. \nConsider a user program waiting for the data to be fetched from a disk. Because of the time disparity between the disk drive and the processor, the program causes the CPU to be idle for a significantly long time. The concept of multiprogramming is inspired by the fact that while the CPU is idle for one program waiting for the some resource to be available, the CPU can execute instructions for other programs. \n\nThe modern operating systems like UNIX not only does multiprogramming, but also timesharing. Timesharing is a variant concept of multiprogramming, and means that the system appears to be executing multiple instances of programs simultaneously. Consider an analogy that a busy individual who needs to cook and do laundry. Two jobs, cooking and washing clothes, can be done one after another, but it is more efficient to be done at the same time, because some stages of both jobs may require waiting for something. While the individual is waiting for the clothes to be dried, it is possible to do something for cooking. \n\nIn a timesharing system like UNIX, a process becomes the basic active entity and the most central key object. The following will discuss the definition, modeling, and properties of processes.

i have used a lot of processes in my current job.  I have used successful processes to create safety programs and human resource programs.  I am trying to learn as much as I can about each process but a lot of the learning just comes from experience.  For instance you learn that a process does not have to be done exactly the same as long as the end results are successful and the process still covers all the bases.

I'm telling u the main points (so far I've studied in OS)...\n\n(1).Windows XP operating system is a multithreaded kernel that provides support for both real-time applications 'n multiple-processors. \n\n(2).On uniprocessor system, when WinXP kernel access a global resource, it temporarily masks interrupts for all interrupt-handlers.\n\n(3). On multiprocessor system, WinXP protects access to global resources using spinlocks. (e.g.- in Solaris, kernel uses spinlocks to protect short-code segments).\n\n(4). For thread synchronization outside the kernel, WinXP provides dispatcher-objects. (several mechanisms 're there... mutexes, semaphores, events, timers etc.)\n\n(5). Dispatcher objects may be either in a 'signaled-state' or in a 'non-signaled-state'. 'Signaled-state' means -- an object is available & a thread won't block while acquiring the object. 'Non-signaled-state' means -- just the opposite (i.e. object's unavailable & thread'll block if tries to acquire that object)\n\nTransitions :\nnon-signaled-->(owner thread releases mutex-lock)-->signaled\nsignaled-->(thread acquires mutex lock)-->non-signaled\n- - - - -- - - -- - - - - - - - - - - - - - - - - - - - - - - - - \nWe've text book of O.S. by 'Silberschatz & Galvin'. Go through it, if possible. Otherwise visit Wikipedia... bye.

Yeah like the 1st person said, to maximize the production. Operations management gives several techniques to maximize the use of resources, say money, people, materials, etc.  It can also help you plan a proyect through pert and cpm. Sorry i cant tell u more, my main language is spanish so i dont really know how to translate this technical words and the names of the techniques. If you understand spanish i can tell you more.

A business process is a recipe for achieving a commercial result. Each business process has inputs, method and outputs. The inputs are a pre-requisite that must be in place before the method can be put into practice. When the method is applied to the inputs, then certain outputs will be created.\n\nA business process is a collection of related structural activities that produce something of value to the organization, its stake holders or its customers. It is, for example, the process through which an organization realizes its services to its customers.\n\nA business process can be part of a larger, encompassing process and can include other business processes that have to be included in its method. In that context a business process can be viewed at various levels of granularity. The linkage of business process with value generation leads some practitioners to view business processes as the workflows which realize an organization's use cases.\n\nA business process can be thought of as a cookbook for running a business; "Answer the phone", "place an order", "produce an invoice" might all be examples of a Business Process.\n\nA business process is usually the result of a business process design or business process reengineering activity.

In computing, the kernel is the central component of most computer operating systems (OSs). Its responsibilities include managing the system's resources and the communication between hardware and software components. As a basic component of an operating system, a kernel provides the lowest level of abstraction layer for the resources (especially memory, processors and I/O devices) that applications must control to perform their function. It typically makes these facilities available to application processes through inter-process communication mechanisms and system calls.\n\nclick here:http://en.wikipedia.org/wiki/Kernel_%28computer_science%29

Stable operating systems tend to have a high degree of configuration management.  That means, changes to the operating system are highly managed.  In the mainframe world, IBM's z/OS operating system uses a product called SMP/E to perform system changes.  This tool is often used in conjunction with strict change control procedures, such as change ticket approvals, peer review meetings, and scheduled implementation.\n\nThe opposite is a system where anyone can just install anything they want whenever they want.  These systems usually tend not to be very stable.

The core functions of the operating system, which do the basic things (reading and writing data) are written in ASM.  Most of the Windows Operating System is coded in C or C++.

did you mean 'accounting management':-\nRecord resource usage and enforce resource usage policy. Accounting Management provides the mechanisms to charge accounts for resource usage and to deny storage resources to overdrawn accounts. Charges may be incurred for the use of any storage system resource, including such typical resources as bytes stored, data transferred, volumes mounted, and desired quality of service.

Contrary to what the processes box says is running and what is not is not always 100% true. Your OS alone depending on what version and what its performing can take a bit of your memory but not that much. Seems to me you have one of two things. You either have a virus running in the back ground using your computer as a slave, or you burnt out one of your memory sticks, which is highly possible.
