https://www.ece.iastate.edu/the-department/history/history-of-computing/ Before we had computer engineers or computer scientists to design and build computers, researchers from many disciplines, including physics, mathematics, and electrical engineering, worked to develop the first computing machines. Iowa State University’s role in the modern computing history began in 1937, when a physics professor and an electrical engineering alumnus (then a graduate student in physics) began working to develop the world’s first electronic digital computer.

Primeros dispositivos digitales de cálculo

La Z1 Trabajaba con cinta perforada para alimentar instrucciones. Máquina electro-mecánica. "The Z1 was the first computer built by the German inventor Konrad Zuse (from 1936 to 1938)." ... " The original prototype was destroyed during a bombing raid in 1943. Only a few sketches and photographs of the mechanical components survived. In the 1980s, Konrad Zuse, who had retired many years earlier, obtained financing from Siemens and other German sponsors for building a full replica of the Z1 which is now housed in Berlin’s Technology Museum.

La famosa ENIAC

Esta ya es electrónica y programable, aunque el re-programarla dependía de cables y conexiones. Los bulbos y relevadores alcanzaron para construir aparatos con un mínimo de partes mecánicas. ENIAC es la más famosa de estas. Ver: Características y detalles

La PC volvió la computación "personal".

La IBM - PC 5150 Una computadora con capacidad de memoria de 512 MB  Un gran espacio para trabajar cómodamente, en su época. Antes hubo varias computadoras caseras. Pero esta provocó el 'boom'. Por dos factores fundamentales: El sistema operativo PC-DOS - MS-DOS (más o menos estandarizado) que permitía grabar en diskettes que podían leerse y utilizarse en otras computadoras (muchas no-IBM, llamadas "compatibles"). La disponibilidad de aplicaciones: de productividad, dibujo y juegos.
