Su uso nació por primera vez en 1998 de la mano de algunos usuarios de la comunidad del software libre, tratando de usarlo como reemplazo al ambiguo nombre original en inglés del software libre (free software). «Free» en inglés significa dos cosas distintas dependiendo del contexto: gratuidad y libertad. Lo cual implica, para el caso que nos ocupa, “software que podemos leer, modificar y redistribuir gratuitamente” (software gratuito) y, además, software libre, según la acepción española de libertad.
El término para algunos no resultó apropiado como reemplazo para el ya tradicional free software, pues eliminaba la idea de libertad, confundida usualmente con la simple gratuidad. No obstante, el término código abierto continúa siendo ambivalente, puesto que se usa en la actualidad por parte de programadores que no ofrecen software libre pero, en cambio, sí ofrecen el código fuente de los programas para su revisión o modificación previamente autorizada por parte de sus pares académicos.
Dada la ausencia de tal ambigüedad en la lengua española, el término software libre es adecuado para referirse a programas que se ofrecen con total libertad de modificación, uso y distribución bajo la regla implícita de no modificar dichas libertades hacia el futuro. De hecho en inglés también se usa el término “libre software” para evitar ambigüedades semánticas.
Desde el punto de vista de una “traducción estrictamente literal”, el significado textual de “código abierto” es que “se puede examinar el código fuente”, por lo que puede ser interpretado como un término más débil y flexible que el del software libre. Sin embargo, ambos movimientos reconocen el mismo conjunto de licencias y mantienen principios equivalentes.
Sin embargo, hay que diferenciar los programas de código abierto, que dan a los usuarios la libertad de mejorarlos, de los programas que simplemente tienen el código fuente disponible, previa restricciones sobre su uso o modificación.
En la actualidad el código abierto se utiliza para definir un movimiento nuevo de software (la Iniciativa Open Source), diferente al movimiento del software libre, incompatible con este último desde el punto de vista filosófico, y completamente equivalente desde el punto de vista práctico, de hecho, ambos movimientos trabajan juntos en el desarrollo práctico de proyectos.
La idea bajo el concepto de código abierto es sencilla: cuando los programadores (en Internet) pueden leer, modificar y redistribuir el código fuente de un programa, éste evoluciona, se desarrolla y mejora. Los usuarios lo adaptan a sus necesidades, corrigen sus errores a una velocidad impresionante, mayor a la aplicada en el desarrollo de software convencional o cerrado, dando como resultado la producción de un mejor software.

S:En fin el día de hoy y como todos los dias los acompañamos sus servidores Sergio Carrasco Y Mónica Juárez, hoy hablaremos de las Ciencias y los científicos que han dejado huella a través del tiempo en está sección de datos interesantes, empezando por:
M: Alessandro Giuseppe Antonio Anastasio Volta (18 de febrero de 1745 – 5 de marzo de 1827) fue un físico italiano, famoso principalmente por haber desarrollado la pila eléctrica en 1800. Alessandro Volta, físico y pionero en los estudios de la electricidad, nació en Como, Lombardía, Italia, el 18 de febrero de 1745, en el seno de una familia de nobles. A los siete años falleció el padre y la familia tuvo que hacerse cargo de su educación. Desde muy temprano se interesó en la física y a pesar del deseo de su familia de que estudiara una carrera jurídica, él se las ingenió para estudiar ciencias.
S: Volta apiló discos de igual tamaño de cobre y de cinc, sólo o con estaño, alternados, que llevan intercalados entre cada uno de ellos un paño humedecido. Esta “pila de discos” empieza y termina con discos de diferente tipo.
Conectando con un alambre los discos situados en los extremos logró que fluyera un flujo eléctrico.
Impregnando el paño en determinadas sales la corriente obtenida era mucho mayor.
