ENIAC

Em 2006 o ENIAC fez 60 anos e seus nome na verdade é um acrônimo para Electronic Numerical Integrator and Computer. Levou 3 anos para ser construído, custou por volta de 500 mil dólares, funcionou pela primeira vez em 14 de fevereiro de 1946, pesava 32 toneladas, media 5,5 metros, consumia 150kW e tinha 17.468 válvulas, cuja vida média era de 3.000 horas, o que obrigava à troca de uma a cada 10 minutos.

O número mais impressionante é o último: em 2004, um chip de silício de 0,5mm quadrados tem a mesma capacidade de processamento que o ENIAC.

Veja mais na wikipedia em português e em inglês. Veja outros números do ENIAC aqui. Você vai precisar buscar por ENIAC para encontrar as informações sobre ele.

    Eu AMO o ENIAC. Comemorei o aniversario de 60 anos dele. Vivo falando da arquitetura de Von Neumann por ahi. Adorei o post. O das bolhas deu um xabu nos videos, nao consegui ver tudo!

    será que alguns dos conceitos do ENIAC ainda continuam vivos ou ele já foi por completo ultrapassado?
