Portability in high-level computer programming is the usability of the same software in different environments. The prerequirement for portability is the generalized abstraction between the application logic and system interfaces. When software with the same functionality is produced for several computing platforms, portability is the key issue for development cost reduction. == Strategies for portability == Software portability may involve: *Transferring installed program files to another computer of basically the same architecture. *Reinstalling a program from distribution files on another computer of basically the same architecture. *Building executable programs for different platforms from source code; this is what is usually understood by "porting". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Software portability」の詳細全文を読む スポンサード リンク
