The fundamental mechanism for event monitoring in Mac OS X. A run loop registers input sources such as sockets, Mach ports, and pipes for a thread; it also enables the delivery of events through these sources. In addition to sources, run loops can also register timers and observers. There is exactly one run loop per thread.
Industry:Software; Computer
A collection of input sources, timer sources, and run loop observers associated with a particular name. When run in a specific mode, a run loop monitors only the sources and observers associated with that mode.
Industry:Software; Computer
An instance of the NSRunLoop class or CFRunLoopRef opaque type. These objects provide the interface for implementing an event-processing loop in a thread.
Industry:Software; Computer
A recipient of notifications during various phases of a run loop’s execution.
Industry:Software; Computer
The period of time during which a programme is being executed, as opposed to compile time or load time. Can also refer to the runtime environment, which designates the set of conventions that arbitrate how software is generated into executable code, how code is mapped into memory, and how functions call one another.
Industry:Software; Computer
A property of an audio unit or other audio device that specifies a time lag, in samples, to allow for improved robustness of driver operation. The safety offset required for a given architecture includes time needed for memory access and to account for inaccuracies in a driver’s timestamp resolution. Safety offset contributes to latency.

(1) (n.) An instantaneous amplitude of the signal in a single audio channel, represented as an integer, floating-point, or fixed-point number. See also fixed-point sample. (2) (v.) To collect samples from an audio source, typically an analogue audio source. Sampling typically involves collecting samples at regular, very brief intervals such as 1/44,100 seconds. (3) (n.) An excerpt of a longer recording. When the excerpt is intended to be played repeatedly, it is called a loop. (4) (v.) To record a sample to use as a loop or for inclusion in a another recording. (5) In QuickTime, a single element of a sequence of time-ordered data.
Industry:Software; Computer
A cryptographic key that cannot be made public without compromising the security of the cryptographic method. In symmetric key cryptography, the secret key is used both to encrypt and decrypt the data. In asymmetric key cryptography, the secret key is paired with a public key. Whichever one is used to encrypt the data, the other is used to decrypt it. See also public key, public key cryptography.
Industry:Software; Computer
Encrypted storage of data that requires a user or process to authenticate itself before the data is decrypted. Secure storage persists when the power is turned off.
