Algorithm :

A set of rules and/or a finite series of steps that will accomplish a particular task.

Iteration :

One of the three basic building blocks of algorithm development (the others are sequence and selection). Iteration refers to operations that are performed repeatedly, usually until some condition is satisfied.

See Also: Selection, Sequence

Selection :

One of the three basic building blocks of algorithm development (the others are sequence and iteration). Selection allows control to flow along a number of possible paths, depending on the circumstance encountered.

See Also: Iteration, Join, Projection, Sequence

Sequence :

One of the three basic building blocks of algorithm development (the others are selection and iteration). A sequence is a series of discrete steps that must be performed in a particular order.
