POSIX: Portable Operating System Interface Standards

What is POSIX?

What is the purpose of POSIX standards?

Answer:

POSIX, which stands for Portable Operating System Interface for Unix, is a family of IEEE standards that define a portable operating system interface to enhance the portability of programs from one operating system to another.

POSIX standards are designed to promote software portability and interoperability across different operating systems. By providing a standardized interface, POSIX ensures that software developers can write programs that can easily be moved from one system to another without significant modifications. This reduces the effort required for software adaptation and allows applications to run on various platforms with minimal changes.

The goal of POSIX is to create a common set of APIs, utilities, and commands that enable developers to write portable, efficient, and reliable software. By adhering to POSIX standards, developers can avoid platform-specific dependencies and ensure compatibility with a wide range of Unix and Unix-like operating systems.
