6 - The Evolution of Early Computing

Before computers existed… technology was already changing the world. The first computer

wasn’t electronic at all. Over two thousand years ago, humans used the

abacus to perform complex calculations faster than many people can calculate today.

Programming existed long before screens or keyboards. In the 1800s, machines were controlled

using punch cards holes in paper that told machines exactly what to do. Early computers

were massive. In the 1940s, computers filled entire rooms, used thousands of

vacuum tubes, and were less powerful than a modern calculator. From wooden beads… to room-sized machines…

this is where modern computers began. Follow for more Simple Tech Facts.
