#WORD PROCESSING OPERATING SYSTEM SOFTWARE#
Word processor is a general application software used for producing such text documents. It involves the tasks such as entering text, editing, formatting, proofing, and printing.
Word processing generally means the task of creating printed materials like letters, reports, thesis, books and so on. What is the difference between word processing and word processor?

To give the appearance of lots of things happening at the same time, the operating system has to switch between different processes thousands of times a second. Today's multicore processors and multiprocessor machines can handle more work, but each processor core is still capable of managing one task at a time. This is complicated because each CPU can only do one thing at a time. Now, the operating system must arrange the execution of applications so that you believe that there are several things happening at once. While interrupts add some complication to the execution of processes in a single-tasking system, the job of the operating system becomes much more complicated in a multitasking system. These non-maskable interrupts (NMIs) must be dealt with immediately, regardless of the other tasks at hand. Some interrupts (such as those from error conditions or problems with memory) are so important that they can't be ignored, such as the delivery of a message to you pointing out the battery in your laptop running out. Sometimes the operating system schedules the priority of processes so that interrupts are masked - that is, the operating system ignores the interrupts from some sources so that a particular job can be finished as quickly as possible. It's as if some part of the computer suddenly raised its hand to ask for the CPU's attention in a lively meeting. 
Interrupts are special signals sent by hardware or software to the CPU. The operating system allows the application to begin running, suspending the execution only long enough to deal with interrupts and user input. In a single-tasking system, the schedule is straightforward. It is processes, rather than applications, that the operating system controls and schedules for execution by the CPU. For example, an operating system can have dozens of background processes running to handle the network, memory management, disk management, virus checks and so on.Ī process, then, is software that performs some action and can be controlled - by a user, by other applications or by the operating system. There are also numerous processes that run without giving you direct evidence that they ever exist. The application you see (word processor, spreadsheet or game) is, indeed, a process, but that application may cause several other processes to begin, for tasks like communications with other devices or other computers. It's tempting to think of a process as an application, but that gives an incomplete picture of how processes relate to the operating system and hardware.
