"backward compatibility"の定義と意味

What is "backward compatibility"?

Backward compatibility is a feature in electronic devices, such as video game consoles or software, that allows newer systems to run or support games, apps, or other content designed for older versions. This feature ensures that players can use their old games or programs without needing to buy new versions or devices. For example, a newer video game console with backward compatibility may allow players to play games from its predecessor, making the transition to the new system smoother. It is especially useful for preserving a player’s game library and ensuring continued access to older content.
