POSIX-compliant systems

POSIX-compliant systems are operating systems that follow a set of standardized rules designed by the Portable Operating System Interface (POSIX). These rules ensure that different systems, like Linux and macOS, can run similar software and communicate effectively. Think of POSIX as a common language for computers, making it easier for developers to create applications that work across various platforms without modification. This standardization enhances compatibility, stability, and interoperability, making POSIX-compliant systems reliable choices for diverse computing environments.
