The onscreen representation of the mouse’s location. The cursor commonly looks like an arrow, but can also assume such shapes as a pencil, a cross, or a paintbrush, depending on the application and the user’s selection. (Also called a pointer.)
Industry:Software; Computer
An AppleScript class used for data that do not belong to any of the other AppleScript classes; see the data class.
Industry:Software; Computer
A data storage and retrieval system. Database servers typically run on a dedicated computer and are accessed by client applications over a network.
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
A dimensionless unit for expressing the ratio of two quantities, abbreviated as dB. The decibel difference between two power levels is equal to 10 times the common logarithm of their ratio. The decibel difference between two voltage levels is equal to 20 times the common logarithm of their ratio. Decibel values are typically associated with a standard voltage or power level. For example, acoustic levels are commonly referenced to 0 dB SPL, equivalent to 20 µPa (micropascals). See also SPL.
Industry:Software; Computer
The calculation of intermediate values relative to known beginning and ending values.
Industry:Software; Computer
In audio, to retrieve the original signal from an encoded representation of it. For lossy encoding schemes such as MP3, the retrieved signal approximates the original signal. See also codec (coder/decoder), encoding.
Industry:Software; Computer
The time lag between one audio event and another. In audio processing, the second event is typically a processed or unprocessed copy of the original event. Delay is a settable parameter in the AUDelay audio unit included in Mac OS X.
Industry:Software; Computer
(1) A way of extending a class in an object-oriented framework. In object-oriented design methodology, delegation is a form of class composition. (2) In AppleScript, the use of a continue statement to call a handler in a parent object or the current application.
Industry:Software; Computer
An attribute in a data model that does not directly correspond to a column in a database. Derived attributes are usually calculated from a SQL expression.
