About
It was originally developed by the Institute of Electrical and Electronics Engineers (IEEE) in the late 1980s and is derived from the UNIX operating system. POSIX encompasses a set of APIs for various functions such as file handling, process control, inter-process communication, and signal handling. These standards ensure that software written to comply with POSIX can run on multiple platforms, allowing for software portability and interoperability. POSIX-compliant operating systems include various versions of UNIX, Linux, and macOS. The Wikipedia page on POSIX provides detailed information about its history, design, components, implementations, and impact on the software industry.
