Computer Science - La informática

  • ENGLISH
Computer science, or computing science, is the study of the theoretical foundations of information and computation and their implementation and application in computer systems. Computer science has many sub-fields; some emphasize the computation of specific results (such as computer graphics), while others relate to properties of computational problems (such as computational complexity theory). Still others focus on the challenges in implementing computations. For example, programming language theory studies approaches to describing computations, while computer programming applies specific programming languages to solve specific computational problems. A further subfield, human-computer interaction, focuses on the challenges in making computers and computations useful, usable and universally accessible to people.

  • SPANISH

La informática o ciencia informática, es el estudio de los fundamentos teóricos de la información y computación y su aplicación en sistemas informáticos. La informática tiene muchos sub-campos, algunos hacen hincapié el los resultados de procesos específicos (cómo gráficos para ordenador), mientras que otras tienen relación con las propiedades de los problemas de procesamiento (como la teoría de la complejidad del procesamiento). En cambio, otros se centran en los retos de las aplicaciones informáticas. Por ejemplo, teorías del lenguaje de programación que estudian el acercamiento a la descripción del procesamiento, mientras la programación de ordenadores impone un lenguaje de programación específico para resolver problemas específicos de procesamiento. Un campo lejano, la interacción persona-ordenador, centra en el reto de fabricar ordenadores útiles, usables y universalmente accesibles para todos.
