The spinning pinwheel is a type of progress indicator and a variation of the mouse pointer used in Apple's macOS to indicate that an application is busy. [ 1 ] Officially, the macOS Human Interface Guidelines refer to it as the spinning wait cursor , [ 2 ] but it is also known by other names.
Using idle time to prepare for the operations a user might do next. Let the user do something productive while the system is busy, for instance, writing information in a form, reading a manual, etc. For instance, in a tabbed browser, the user can read one page while loading another. Deliver intermediate results, before the operation is finished.
English: This textbook consists of notes for the CSci 1001 Overview of Computer Science class at the University of Minnesota-Twin Cities. More information about that class and these notes are in the opening chapter. The original version of these notes was used in the Spring 2014 offering of that class.
The magazine said that the book was not easy to read, but that it would expose experienced programmers to both old and new topics. [8] A review of SICP as an undergraduate textbook by Philip Wadler noted the weaknesses of the Scheme language as an introductory language for a computer science course. [9]
In many cases programs may appear to be hung, but are making slow progress, and waiting a few minutes will allow the task to complete. Modern operating systems provide a mechanism for terminating hung processes, for instance, with the Unix kill command, or through a graphical means such as the Task Manager's "end task" button in Windows (select the particular process in the list and press "end ...
Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors. This contrasts with system software, which is ...
Computer science is the study of computation, information, and automation. [1] [2] [3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software).

In his book The Humane Interface, Jef Raskin defines modality as follows: "An human-machine interface is modal with respect to a given gesture when (1) the current state of the interface is not the user's locus of attention and (2) the interface will execute one among several different responses to the gesture, depending on the system's current state."
