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.
(1) In Mac OS X, a connection that involves the sending of a message from one object to another when a certain user action occurs. For example, when a user presses a button, the button object calls the action method of its target object to notify that object that the action occurred. (2) In Automator, a building block used to build workflows.
Industry:Software; Computer
(1) Apple Developer Connection. The primary source for technical and business resources and information for anyone developing for Apple’s software and hardware platforms anywhere in the world. It includes programs, products, and services and a website filled with up-to-date technical documentation for existing and emerging Apple technologies. (2) Analog-to-digital converter. Circuitry that converts analog signals to corresponding digital code using sampling and quantization. ADCs are characterized by sample rate, amplitude resolution in terms of bit depth, quantization error and other distortion characteristics, and noise floor. Professional audio work usually employs ADCs with a linear response. Compare DAC. See also quantization, sample.
Industry:Software; Computer
A model for extending a continuous selection using Shift-click, in which new text is added to a selection. Compare fixed-point model.
Industry:Software; Computer
A technology for managing names, addresses, phone numbers, and other contact-related information. Mac OS X provides the Address Book application for users to manage contact data. It also provides the Address Book framework so that applications can programmatically manage the data.
Industry:Software; Computer
The virtual address ranges available to a given task (the task may be the kernel). In Mac OS X, processes do not share the same address space. The address spaces of multiple processes can, however, point to the same physical address ranges. This is referred to as shared memory.
Industry:Software; Computer
A group with special administrative privileges. For example, only members of the admin group can open locked system preferences or install software. See also wheel group.
Industry:Software; Computer
A user in the admin group. The user who installs Mac OS X is automatically assigned to the admin group. An administrator has fewer privileges than root, but more privileges than a normal user. An administrator cannot create, delete, or move files in the system domain.
Industry:Software; Computer
Adaptive delta pulse code modulation. A variant of pulse-code modulation, and an extension of DPCM, that varies quantization step size to minimize bit rate for a given dynamic range.
Industry:Software; Computer
The distance between the end of one glyph’s advance and the next glyph’s real position.
Industry:Software; Computer
The distance from the top of a glyph to the bottom of the glyph, including the top-side bearing and bottom-side bearing.
