  This page describes in-depth, the four basic periods of information technology systems: pre-mechanical, mechanical, electromechanical and electronic. It is an excellent resource to use to teach the different periods and technologies and has very good pictures of the devices, as well as their inventors.

  Baggage se inspiró en el telar de Jacquard para diseñar su Máquina diferencial.  La máquina estaba concebida para realizar cálculos, almacenar y seleccionar información, resolver problemas y entregar resultados impresos mediante engranjes metálicos y tarjetas perforadas inspiradas en las inventadas por Jacquard. La novia de Babbage, Ada Augusta Byron, luego Condesa de Lovelace e hija del poeta inglés Lord Byron, le ayudó en el desarrollo del concepto de la Máquina Diferencial, creando programas para su anterior versión, la Máquina Analítica, inscritos en las tarjetas perforadas. Es por ello reconocida como el primer programador y de ella es la frase "podríamos decir con propiedad que la Máquina Analítica teje patrones algebraicos como el telar de Jacquard teje flores y hojas".

  
  

  Esta frase inpirará a Lev Manovich: "Thus, a programmed machine was already synthesizing images even before it was put to process numbers. The connection between the Jacquard loom and the Analytical Engine is not something historians of computers make much of, since for them image synthesis and manipulation represent just one application of the modern digital computer among thousands of others; but for a historian of new media it is full of significance". How Media Became New.

  
  

  Babbage no pudo ver construida su máquina en vida pero colaboró en la construcción de un equipo similar desarrollado por el impresor sueco George Scheutz y basado en su máquina diferencial. En cualquier caso su trabajo le ha valido la consideración de uno de los padres de la informática.
