Industry:Software; Computer
A special type of memory that is substantially faster than typical main memory (RAM). When a program asks the CPU to read or write data in memory, it first checks 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.

(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 analog signals to corresponding digital code using sampling and quantization. ADCs are characterized 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.
