FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Backward compatible (also known as downward compatible or backward compatibility) refers to a hardware or software system that can successfully use interfaces and data from earlier versions of the system or with other systems.

Detailed explanation-2: -A backward compatible system is newer hardware that is backward compatible with older hardware versions of the same model. For example, PlayStation 3 (PS3) is backward compatible with PlayStation 1 (PS1) and most PlayStation 2 (PS2) systems. Hardware that is backward compatible can vary with the model and version.

Detailed explanation-3: -Backward compatibility is a design that is compatible with previous versions of itself. Forward compatibility is a design that is compatible with future versions of itself.

Detailed explanation-4: -Forward compatibility or upward compatibility is a design characteristic that allows a system to accept input intended for a later version of itself. The concept can be applied to entire systems, electrical interfaces, telecommunication signals, data communication protocols, file formats, and programming languages.
