Apple Inc., formerly Apple Computer, Inc., is an American multinational corporation headquartered in Cupertino, California, that designs, develops, and sells consumer electronics, computer software and personal computers.
A process by which the current keyboard script is compared to the script of the font at the current insertion point. If the two don’t match, one or the other is changed so the two scripts are the same. In most cases, when the user starts typing, the font is automatically replaced with one belonging to the keyboard script, although it is possible to synchronize in the other direction.
Industry:Software; Computer
A window control (the middle yellow button that appears at the top left) that the user clicks to put a window into the Dock.
Industry:Software; Computer
One of the QuickTime media types, in which sequences of sounds and tones are generated.
Industry:Software; Computer
The Core Audio programming construct that applications use to play MIDI or other event data.
Industry:Software; Computer
A special user with very little access. To prevent someone running as root or as an administrator on one system from gaining control over another system through a network connection, such users are often mapped to the nobody user on the remote system.
Industry:Software; Computer
A programmatic mechanism for alerting interested recipients (observers) that some event has occurred during program execution. The observers can be users, other processes, or even the same process that originates the notification. In Mac OS X, the term is used to identify specific mechanisms that are variations of the basic meaning. In the kernel environment, notification is sometimes used to identify a message sent via IPC from kernel space to user space. Distributed notifications provide a way for a process to broadcast an alert (along with additional data) to any other process that makes itself an observer of that notification. Finally, the Notification Manager (a Carbon manager) lets background programs notify users—through blinking icons in the menu bar, by sounds, or by dialogs—that their intercession is required. In Enterprise Objects, it’s a mechanism that provides an asynchronous communication infrastructure between objects.
Industry:Software; Computer
The highest frequency signal that can be faithfully recorded for a given sampling rate. Attempts to sample a signal containing higher frequencies results in the generation of an alias signal below the Nyquist frequency. The Nyquist frequency is half the sampling rate. See also visual context.
Industry:Software; Computer
A structure of QuickTime VR data that forms a virtual-world environment within which the user can navigate.
Industry:Software; Computer
An address to which a hardware device, such as a memory chip, can directly respond. Programs, including the Mach kernel, use virtual addresses that are translated to physical addresses by mapping hardware controlled by the Mach kernel.
