macintosh user interface — (operating system) The graphical user interface used by Apple Computer's Macintosh family of personal computers, based on graphical representations of familiar office objects (sheets of paper, files, wastepaper bin, etc.) positioned on a two-dimensional "desktop" workspace. Programs and data files are represented on screen by small pictures (icons). An object is selected by moving a mouse over the real desktop which correspondingly moves the pointer on screen. When the pointer is over an icon on screen, the icon is selected by pressing the button on the mouse. A hierarchical file system is provided that lets a user "drag" a document (a file) icon into and out of a folder (directory) icon. Folders can also contain other folders and so on. To delete a document, its icon is dragged into a trash can icon. For people that are not computer enthusiasts, managing files on the Macintosh is easier than using the MS-DOS or Unix command-line interpreter. The Macintosh always displays a row of menu titles at the top of the screen. When a mouse button is pressed over a title, a pull-down menu appears below it. With the mouse button held down, the option within the menu is selected by pointing to it and then releasing the button. Unlike the IBM PC, which, prior to Microsoft Windows had no standard graphical user interface, Macintosh developers almost always conform to the Macintosh interface. As a result, users are comfortable with the interface of a new program from the start even if it takes a while to learn all the rest of it. They know there will be a row of menu options at the top of the screen, and basic tasks are always performed in the same way. Apple also keeps technical jargon down to a minimum. Although the Macintosh user interface provides consistency; it does not make up for an application program that is not designed well. Not only must the application's menus be clear and understandable, but the locations on screen that a user points to must be considered. Since the mouse is the major selecting method on a Macintosh, mouse movement should be kept to a minimum. In addition, for experienced typists, the mouse is a cumbersome substitute for well-designed keyboard commands, especially for intensive text editing.

pre-emptive multitasking — (operating system, parallel) A type of multitasking where the scheduler can interrupt and suspend ("swap out") the currently running task in order to start or continue running ("swap in") another task. The tasks under pre-emptive multitasking can be written as though they were the only task and the scheduler decides when to swap them. The scheduler must ensure that when swapping tasks, sufficient state is saved and restored that tasks do not interfere. The length of time for which a process runs is known as its "time slice" and may depend on the task's priority or its use of resources such as memory and I/O. This contrasts with cooperative multitasking where each task must include calls to allow it to be descheduled periodically.
