In QuickTime, a single element in a user data list, such as a modification date or copyright notice.
Industry:Software; Computer
Reduction of the dynamic range of an audio signal, typically by reducing the gain ratio for amplitudes above a specific level. Compare limiting.
Industry:Software; Computer
An iPhone OS API that produces cryptographically secure pseudorandom numbers.

Digital certificate. In order for a digital certificate to be trusted, the certification authority must be a trusted organisation that authenticates an applicant before issuing a certificate.
Industry:Software; Computer
Hierarchical File System. The Mac OS Standard file-system format, used to represent a collection of files as a hierarchy of directories (folders), each of which may contain either files or other folders. HFS is a two-fork volume format.
Industry:Software; Computer
Application or framework used by web service providers and consumers to process SOAP messages.
Industry:Software; Computer
A special type of memory that is substantially faster than typical main memory (RAM). When a programme asks the CPU to read or write data in memory, it first cheques to see whether this data is stored in cache memory (because it will be faster to retrieve or write). Cache sizes are usually quite small though, (under 2 MB) so in order to make use of it, the data must be small enough to fit in the cache.

Core Audio Format. Apple’s universal audio file format. CAF files are chunk-based and can contain AAC, MP3, and PCM audio data, among many other audio data formats, as well as MIDI data. See also chunk, PCM.

(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 analogue signals to corresponding digital code using sampling and quantization. ADCs are characterised 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.

(1) In BSD-derived systems, a socket refers to different entities in user and kernel operations. For a user process, a socket is a file descriptor that has been allocated using socket(2). For the kernel, a socket is the data structure that is allocated when the kernel’s implementation of the socket(2) call is made. (2) In AppleTalk protocols, a socket serves the same purpose as a “port” in IP transport protocols.
