Hard disk drives, include space generally, contiguous free space (such as for swap space), and use of multiple physical devices ("spindles"), since using multiple devices allows parallelism.Random access memory and virtual memory – see memory management.CPU, both time on a single CPU and use of multiple CPUs – see multitasking.Managing resources is referred to as resource management, and includes both preventing resource leaks (releasing a resource when a process has finished using it) and dealing with resource contention (when multiple processes wish to access a limited resource). Virtual system resources include files (concretely file handles), network connections (concretely network sockets), and memory areas. Every internal system component is a resource. Every device connected to a computer system is a resource. In computing, a system resource, or simply resource, is any physical or virtual component of limited availability within a computer system. And finally, it could be used to distribute nearly all of the components of an application in a single file, reducing clutter and simplifying application installation and removal. Second, because all the pictures and text were stored separately in a resource fork, it could be used to allow a non-programmer to translate an application for a foreign market, a process called internationalization and localization. This software variant of virtual memory helped Apple to reduce the memory requirements of the Apple Lisa from 1 MB to 128 KB in the Macintosh. First, it was used to store all graphical data on disk until it was needed, then retrieved, drawn on the screen, and thrown away. Originally conceived and implemented by programmer Bruce Horn, the resource fork was used for three purposes with Macintosh file system. The resource fork is used mostly by executables, but every file is able to have a resource fork. For example, a word processing file might store its text in the data fork, while storing any embedded images in the same file's resource fork. A resource fork stores information in a specific form, containing details such as icon bitmaps, the shapes of windows, definitions of menus and their contents, and application code ( machine code). The resource fork is a fork or section of a file on the Apple Mac OS operating system used to store structured data along with the unstructured data stored within the data fork.
