The evolution of computing is a story of bold ambition and tireless innovation. In the early 20th century, complex calculations were performed manually or with basic mechanical devices, often taking days or even weeks to complete. But as the world became more reliant on data, military strategy, and scientific exploration, the need for faster, more powerful computing machines grew urgent.
This necessity drove a wave of technological breakthroughs and led to the creation of the first supercomputers. Though they were slow by modern standards, these early computers revolutionized the way information was processed and laid the groundwork for the devices we use today.
So, how did early computers go from being military tools to commercial products? What key innovations made it possible to move from bulky, vacuum-tube machines to modern laptops? Click through this gallery to find out.
