A string in [[computing]] is an important datatype commonly found in many [[programming language|programming languages]] to represent text. The exact semantics of the datatype vary from language to language but it usually has the core semantics of representedrepresenting a finite ordered sequence of [[character]]s (a group a characters "strung" together, hence the name). It may also refer to strings of other datatypes other than characters (such as strings of numbers or vectors).

In the [[theory of computation]] strings are also often called words, and the letters are elements from an arbitrary finite set.
