Cross-platform

In computing, cross-platform (also known as multi-platform) is a term used to refer to computer software or computing methods and concepts that are implemented and inter-operate on multiple computer platforms.

For example, a cross-platform application may run on Microsoft Windows on the x86 architecture, GNU/Linux on the x86 architecture and Mac OS X on either the PowerPC or x86 based Apple Macintosh systems. A cross-platform application may run on as many as all existing platforms, or on as few as two platforms.
