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 acts as the brain, performing millions of these tiny switch operations every second to render a video, send an email, or calculate a spreadsheet. 4. Modern Era: Cloud, AI, and Beyond How Computers Work: The Evolution of Technology
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 0 (Off): Electricity is blocked
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) Modern Era: Cloud, AI, and Beyond By the
