POSIXpõhiseid

POSIXpõhiseid refers to systems or software that adhere to the POSIX standard. POSIX, which stands for Portable Operating System Interface, is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. It defines a common application programming interface (API), along with hardware and software interfaces, for applications to use.

The primary goal of POSIX is to enable applications written for one POSIX-compliant system to be easily ported to another POSIX-compliant system with minimal or no modification. This includes aspects like file system structure, command-line utilities, and programming interfaces for tasks such as process management, file I/O, and memory management.

Operating systems like Linux, macOS, and various Unix-like systems are considered POSIX-compliant. This compliance allows developers to create software that can run across a wide range of these platforms. When software is described as POSIXpõhiseid, it means it is designed to leverage these common interfaces and behaviors, enhancing its portability and interoperability. The standard has evolved over time, with different versions (e.g., POSIX.1, POSIX.1-2001) addressing new features and functionalities.
