Apple Inc., formerly Apple Computer, Inc., is an American multinational corporation headquartered in Cupertino, California, that designs, develops, and sells consumer electronics, computer software and personal computers.
A special user with very little access. To prevent someone running as root or as an administrator on one system from gaining control over another system through a network connection, such users are often mapped to the nobody user on the remote system.
Industry:Software; Computer
(1) In object-oriented programming, a programming unit that groups together a data structure (fields) and the operations (methods) that can use or affect that data. Objects are the principal building blocks of object-oriented programs. (2) In Mach, a collection of data, with permissions and ownership. (3) In AppleScript, an instantiation of a class definition, which can include properties and actions. (4) A group of bright, high-intensity pixels in an image, as opposed to the darker pixels, which are considered part of the background.
Industry:Software; Computer
(1) (n.) The smallest unit (in bytes) of information that the virtual memory system can transfer between physical memory and backing store. (2) (v.) To transfer pages between physical memory and backing store. (3) (n.) In Quartz, the virtual canvas that Quartz paints to.
Industry:Software; Computer
A variable that is available anywhere in the script in which it is defined.

In the I/O Kit, a collection of software abstractions that are common to all devices of a particular category. Families provide functionality and services to drivers. Examples of families include protocol families (such as SCSI, USB, and Firewire), storage families (disk drives), network families, and families that describe human interface devices (mouse and keyboard).
Industry:Software; Computer
A set of properties specifying the kinds of devices a driver can support. This information is stored in an XML matching dictionary defined in the information property list (Info.plist) file in the driver’s KEXT bundle. A single driver may present one or more personalities for matching; each personality specifies a class to instantiate. Such instances are passed a reference to the personality dictionary at initialization.
Industry:Software; Computer
An address to which a hardware device, such as a memory chip, can directly respond. Programs, including the Mach kernel, use virtual addresses that are translated to physical addresses by mapping hardware controlled by the Mach kernel.
Industry:Software; Computer
Electronic circuitry contained in random-access memory (RAM) chips, used to temporarily hold information at execution time. Addresses in a process’s virtual memory are mapped to addresses in physical memory. See also virtual memory
