The modern definition encompasses the idea of multi-programming tasks, but the concept extends the ability to use different parts called threads at a time. The basic idea is that most programs cannot be treated as a series of small elements called tasks. Sometimes these tasks and completed sequentially, one at a time. For example, Task 2, for example, before the results of Task 1 continues. Another time, some or the entire program is useful for solving problems, regardless of the task. And of course you can handle situations where a common task, Task3 Task2 and can be used alone, but must await the completion of four tasks. Another piece of the puzzle is that many devices such as tape and disk drives can operate independently. Task I / O can be read as a system disk to the program is designed to work independently and to the left, while the operating system is ready to perform another task or program. The operating system and the suspension of the table list the tasks that are "executable" phase, which is the highest priority, for example, B. In this connection, the program awaits the identification number of the Program on standby to disk, and keeps reading. The program is stored in the restored B & B, the program starts. But when the program hangs after reboot? Well, the device I / O should be noted that the process is complete, and that by breaking the device. Disconnect the device is said to messages sent by the CPU and peripheral that requires attention. For example, if you press the key on the keyboard, the keyboard use stored value and keystrokes and sends the CPU interrupts and says that he expects the data. As the name suggests, can be interrupted at any time, and the core should be noted that although no immediate restart is possible. The reaction in this case, the base is the time to read the status changes to "run" phase. This program is a candidate to run again, and finally a prioritization of the program depends on its place in the sun again. Peeling the onion layers of nested complex business processes is the key to a global vision and great faith. Fortunately, Unix and Linux are a few simple commands, like so many programs running as you want and you can track your progress. Some Unix and Linux using a GUI to a very good combination. In this interface, you can run multiple programs without any command-line. Currently, there are some versions of Linux, the graphical user interface like Windows. You know that people feel comfortable in Windows, and if people think the same type of graphical user interface on Linux, you feel comfortable with it.
