The term '''redundant code''' may also be used to described code that has any form of redundancy, such as recomputing a value that has previously been calculated and is still available, code that is never executed, or a result which is executed and not used. Redundant code may also be used to refer to code that is executed but has no effect on the output of a program – however this is usually known as [[dead code]]. A [[NOP]] might be considered to be redundant code that has been explicitly inserted to pad out the [[instruction (computer science)|instruction]] stream or introduce a time delay. [[Identifier]]s that are declared but never referenced are usually termed as [[redundant declaration]]s.
