All operating systems (OSs) in this section support POSIX standards fully or partly. POSIX is an acronym for: Portable Operating System Interface for UniX. Much like TRON, POSIX is not a body of computer code that is compiled and run on some processor. Rather, it is a set of standards (IEEE 1003.1): interfaces, design guidelines, software design specifications, defining (for creating) the computer code that will become language interfaces between an OS kernel and its programs, to give compatibility when moving programs between compatible systems. POSIX is made mostly of features from BSD Unix and Unix System V. Much like Open Source software, all POSIX standards are copyrighted (by the Institute of Electrical and Electronics Engineers, Inc.

The Portable Operating System Interface ( POSIX ) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. (wikipedia)
- Wikipedia: The Portable Operating System Interface is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. POSIX defines the application programming interface, along with command line shells and utility interfaces, for software compatibility with variants of Unix and other operating systems.
- POSIX Category
- POSIX signal - Signals are a limited form of inter-process communication, typically used in Unix, Unix-like, and other POSIX-compliant operating systems. A signal is an notification sent to a process or to a specific thread within the same process in order to notify it of an event that occurred.
- POSIX Threads - POSIX Threads, usually referred to as pthreads, is an execution model that exists independently from a language, as well as a parallel execution model. It allows a program to control multiple different flows of work that overlap in time.
- TRON project ? alternative OS standards to POSIX.
- Common User Access ? User interface standard.
- Interix ? a full-featured POSIX and Unix environment subsystem for Microsoft's Windows NT-based operating systems.
- C POSIX library - The C POSIX library is a specification of a C standard library for POSIX systems. It was developed at the same time as the ANSI C standard. Some effort was made to make POSIX compatible with standard C; POSIX includes additional functions to those introduced in standard C.
