The true "big bang" of computing happened in 1947 with the invention of the . This tiny device replaced bulky vacuum tubes, acting as a simple on/off switch for electrical signals.
Whether you are a , a tech enthusiast , or just someone curious about the silicon chip in your pocket, understanding the evolution of technology helps demystify the modern world. 1. The Early Days: From Gears to Vacuum Tubes How Computers Work: The Evolution of Technology
Despite their complexity, computers are actually quite simple at their core. They operate using —a language made entirely of 1s and 0s . 1 (On): Electricity is flowing. 0 (Off): Electricity is blocked. The true "big bang" of computing happened in
By the 1940s, we entered the era of . These machines, like the ENIAC , were the size of entire rooms. They were revolutionary but incredibly hot, fragile, and power-hungry. 2. The Great Shrink: Transistors and Microchips 1 (On): Electricity is flowing
Eventually, thousands (now billions) of these transistors were etched onto a single silicon wafer , creating the microchips that power everything today. 3. How a Computer "Thinks" (Binary & Logic)
