The journey didn’t start with electricity. Early "computers" like were entirely mechanical , using gears and levers to solve math problems.
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 How Computers Work: The Evolution of Technology
Today, we are no longer limited by the hardware on our desks. The journey didn’t start with electricity
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) like the ENIAC
