Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Forward compatibility or upward compatibility is the ability of a system to gracefully accept input intended for later versions of itself. The introduction of a forward compatible technology implies that old devices partly can understand data generated by new devices. The concept can be applied to electrical interfaces, telecommunication signals, data communication protocols, file formats, and computer programming languages. A standard supports forward compatibility if older product versions can receive, read, view, play or execute the new standard. Although forward compatibility and extensibility are similar, they are not the same. A forward compatible system can accept data from a future version of itself and pick out the "known" part of the data. An example is a text-only word processor ignoring picture data from a future version. An extensible system is one that can be upgraded to fully handle the new data in the newer input format. An example is a text-only word processor that can be upgraded to handle picture data.
