- imperative language — (language) Any programming language that specifies explicit manipulation of the state of the computer system, not to be confused with a procedural language, which specifies an explicit sequence of steps to perform. An example of an imperative (but non-procedural) language is a data manipulation language for a relational database management system. This specifies changes to the database but does not necessarily require anyone to specify a sequence of steps. Both contrast with declarative languages, which specify neither explicit state manipulation nor a sequence of steps.

- iterative deepening — (algorithm) A graph search algorithm that will find the shortest path with some given property, even when the graph contains cycles. When searching for a path through a graph, starting at a given initial node, where the path (or its end node) has some desired property, a depth-first search may never find a solution if it enters a cycle in the graph. Rather than avoiding cycles (i.e. never extend a path with a node it already contains), iterative deepening explores all paths up to length (or "depth") N, starting from N=0 and increasing N until a solution is found.

- longitudinal parity — (storage, communications) An extra byte (or word) appended to a block of data in order to reveal corruption of the data.

Longitudinal parity allows single bit errors to be detected.
