<H1>De esta manera comienza la historia de la Informática</H1> *El origen de las máquinas de cálculo se encuentra en el ábaco chino, que era una tablilla dividida en columnas donde en primera, contando desde la derecha, correspondía a las unidades, la siguiente a las decenas, y así sucesivamente. La forma para poder usar era manualmente, aunque sólo se podían realizar sumas y restas.* **Abaco Chino** <center></center> *En el siglo XVII aconteció otro de los hitos importantes en la historia de la informática, cuando el científico francés Blas Pascal inventó una máquina calculadora. Solo podía hacer sumas y restas.* **Pascalina** <center></center> *Sirvió como inspiración para que el alemán Leibnitz, en el siglo XVIII, desarollarse más tarde una máquina que también era capaz de hacer multiplicaciones y divisiones.* **Leibnitz calculadora** <center>https://steemitimages.com/500x500/https://cdn.steemitimages.com/DQmPnsVc24hnVVLyzjkjPAERuzi1XMxkjT8THWQd5Lfe1AS/Leibnitz%20calculadora.jpg)</center> *En el siglo XIX el matemático inglés Babbage desarrolló lo que se llamó "Máquina Analítica", que ya podía realizar cualquier operación. Disponía de memoria para unos 1000 dígitos y funciones auxiliares. Sin embargo, al igual que sus predecesoras, era una máquina mecánica, lo que presentaba diversos problemas.* **Maquina Analitica** <center>https://steemitimages.com/500x500/https://cdn.steemitimages.com/DQmR5YRTz3uCy1BphUXopH3SjSpEv9yNRrPpcM3SbNBb49A/Maquina%20Analitica.jpg)</center> *En el siglo XX, y gracias al desarrollo de la electrónica, se reemplazan los sistemas de engranaje y varillas por impulsos eléctricos, que dió lugar más tarde, concretamente entorno a la segunda guerra mundial, a lo que se considera el primer ordenador, el Mark I, cuyo funcionamiento se basaba en interruptores mecánicos.* **Mark 1** <center>https://steemitimages.com/500x500/https://cdn.steemitimages.com/DQmZEYHeSwcMkprYpf3eWKsN3KSmL3ZCnyf8t5qcCehhkEZ/Mark%201.jpg)</center> *En 1944 apareció el Eniac, que fué el primer ordenador con fines prácticos que existió.* **Eniac 1** <center>https://steemitimages.com/500x500/https://cdn.steemitimages.com/DQmZfGoKJwhHq2Jvm8uC6ontZpUsJqjKw2hie1gxsZnAaRu/computadora-eniac-1.jpg</center> *Y en 1951 el Univac I con fines similares.* **Unicac I** <center>https://steemitimages.com/500x500/https://cdn.steemitimages.com/DQmd1BEYdfjXtZQJHr9wnXGNsQgYcB8maifDRjHYXHRaa3z/Univac1.jpg</center> *Univac II con fines muy similares.* **Unicac II** <div class="pull-left">https://cdn.steemitimages.com/DQmdA7PeW42TJWifdrHpkWgxHuegQUd9EGMUUY2LkyosgT9/Unicac%202%20Segunda%20IMG%20.jpg</div> <div class="pull-right">https://cdn.steemitimages.com/DQmWPpyQhLC3aUVQEgJrbwFLES4JdUnGWvGJGWaMs1t5aT3/Unicac%202.jpg</div> <br> <blockquote>En el Siguiente Post tendremos Generaciones de Computadoras</blockquote>
