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 computer in which the logic gates are based on quantum phenomena such as electron spin rather than mechanical or conventional electronic components. Because of the superposition of quantum states (a consequence of the Heisenberg Uncertainty Principle), a properly designed quantum computer can in principle perform simultaneously certain types of calculations that require a huge number of sequential operations in a classic computer. Consequently, factoring large numbers should be several orders of magnitude faster on a quantum computer than on present-day supercomputers. Because the strength of most modern cryptographic methods depends on the difficulty of making such calculations, a practical quantum computer would break most cryptographic schemes in common use. Although small proof-of-concept quantum computers have been constructed, no such machine capable of solving practical problems has yet been demonstrated.
Industry:Software; Computer
American Standard Code for Information Interchange. A 7-bit character set (commonly represented using 8 bits) that defines 128 unique character codes. See also Unicode.
Industry:Software; Computer
An advanced object-oriented development platform in Mac OS X. Cocoa is a set of frameworks used for the rapid development of full-featured applications in the Objective-C language. It is based on the integration of OpenStep, Apple technologies, and Java.
Industry:Software; Computer
A suite of network protocols that is standard on Macintosh computers and can be integrated with other network systems, such as the Internet.

In Xcode, a view that contains a list of a project’s contents.

In Xcode, the code line indicated by the pointer at the time you choose a debugging command from the shortcut menu.
Industry:Software; Computer
An incrementing of the reference count of an object. An object with a positive reference count is not freed. (A newly created object has a reference count of one.) Drivers can ensure the persistence of an object beyond the present scope by retaining it. Many APIs automatically execute a retain on the caller’s behalf, particularly APIs used to create or gain access to objects. Retains and releases must be carefully balanced; too many retains will result in wired memory leak. Compare release.
Industry:Software; Computer
A system for digitally encoding sound that stores the amplitude values as a signed number—silence is represented by a sample with a value of 0. For example, with 8-bit sound samples, twos-complement values would range from –128 to 127, with 0 meaning silence. The Audio Interchange File Format (AIFF) stores samples in twos-complement form. Compare offset-binary encoding.
Industry:Software; Computer
A collection of preallocated buffers that can be used over and over. Keeping a pool of buffers available requires less overhead than allocating and deallocating a buffer each time it is needed.
