Cadenas

A cadena (plural: cadenas) is a Spanish word that translates directly to "chain" in English. In computing and data processing contexts, especially when discussing Spanish-language programming or documentation, cadena often refers to a string, which is a sequence of characters.

Specifically, cadena represents an ordered collection of symbols taken from some alphabet. The alphabet typically consists of letters, numbers, punctuation marks, and control characters. Strings are fundamental data types used to store and manipulate text in virtually all programming languages. Operations that can be performed on strings include concatenation (joining strings together), substring extraction (taking a portion of a string), comparison (determining if two strings are equal), searching (finding a specific character or sequence of characters within a string), and manipulation such as converting to uppercase or lowercase.

The term cadena de caracteres is also frequently used to emphasize that the data being described is a sequence of characters, further reinforcing its equivalence to the English "string."
