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 sequence of actions to accomplish some task. In cryptography, refers to a sequence of actions, usually mathematical calculations, performed on data to encrypt or decrypt it.
Industry:Software; Computer
A channel dedicated to representing how opaque a given pixel is. Unlike the red, green, and blue channels, which specify the intensity of their respective colors, the alpha channel specifies the opacity of the entire pixel. For example, if a pixel was defined using float values ranging from 0.0 to 1.0, an alpha channel intensity of 1.0 would indicate 100% opacity, and an intensity of 0.0 would indicate 0% opacity, or transparent.
Industry:Software; Computer
Algorithmic reduction of data size to improve storage or transmission efficiency. Data compression can be lossy or lossless. Compression is a special case of encoding. See also lossless compression, lossy compression, perceptual coding.
Industry:Software; Computer
An abstract identifier used to access a file, socket, or other system resource.
Industry:Software; Computer
In Carbon, a library or set of related libraries that define a programming interface.
Industry:Software; Computer
A filter that alters IP traffic each time it enters the protocol stack. By its very nature, an IP filter can only filter in-band communication.
Industry:Software; Computer
A user-driven installation process. Users drag a product’s files to a location of their choosing in their file system. Compare window.
