Binary portability refers to the ability of a compiled program, specifically its binary executable, to run on different computer systems without requiring recompilation. This concept is closely related to cross-platform compatibility. A truly binary portable program can be transferred from one machine to another, even if they have different operating systems or hardware architectures, and function as intended.

However, achieving true binary portability is often challenging due to various factors. These include differences in instruction set architectures (ISAs), such as x86 versus ARM, as well as variations in operating system interfaces (APIs) and system libraries. Even seemingly minor differences in how data types are represented or how memory is managed can prevent a binary from running correctly on a different platform.

To address these challenges, developers often employ strategies like using cross-compilers, which allow a program to be compiled on one system for execution on another. Alternatively, some systems provide abstraction layers or virtual machines that simulate a consistent environment, enabling binaries compiled for that environment to run across diverse underlying hardware. Standards like POSIX aim to provide a common interface, increasing the likelihood of binary portability across Unix-like systems, though hardware differences can still be a barrier. The goal of binary portability is to reduce the effort required to deploy and run software on a wider range of devices.
