Backward compatible (or sometimes backward-compatible or backwards compatible) refers to a hardware or software system that can successfully use interfaces and data from earlier versions of the system or with other systems. For example, SVG partly replaces PNG, viz., in cases where PNG is used to display diagrams or graphs. An example of backwards compatibility is that they rename one of the methods in ICS but still implement a deprecated version of the old method and have it forward to the new implementation. The benefits of backward compatibility is that it will appeal to users who are currently using a certain device, and allows for inexpensive upgrades, as games can be used on both versions.
