Portable operating system interface (POSIX)

Portable operating system interface (POSIX)

Portable Operating System Interface (POSIX) is a set of standardised APIs and interfaces that define how software should interact with an operating system. POSIX ensures compatibility and portability of applications across different UNIX-like operating systems by standardising system calls, command-line interfaces, and utility functions. It is widely used to maintain cross-platform compatibility in software development.
