Editing OpenStep (section)

==Description==
{{Unsourced section|date=March 2023}}
OpenStep differs from NeXTSTEP in various ways:

*NeXTSTEP is an operating system, whereas OpenStep is an API.
*Unlike NeXTSTEP, OpenStep does not require the [[Mach kernel]].
*Each version of NeXTSTEP has a specific [[endianness]]: [[big endian]] for [[Motorola 68K]] processors, and [[little endian]] for [[x86]] processors, for example. OpenStep is "endian-free".
*OpenStep introduces new [[Class (computer programming)|classes]] and [[memory management]] capabilities.

The OpenStep API specification defines three major components: Foundation Kit, the [[software framework]]; [[Application Kit]], the [[GUI]] and graphics front-end; and Display PostScript, a 2D graphics system (for drawing windows and other graphics on the screen).
