backward compatibility

Backward compatibility refers to the ability of newer products, systems, or technologies to work with older versions or formats. For example, if you buy a new video game console, backward compatibility means it can play games made for the previous console version. This concept is important because it allows users to continue using their existing software or hardware without needing to replace everything when they upgrade. It enhances user experience by providing continuity and reducing frustration associated with obsolescence. Overall, it ensures that advancements do not leave users behind who may not have immediate access to the latest technology.
