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
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
We use massive data centers to process information remotely. By the 1940s, we entered the era of
The next frontier, which uses quantum bits (qubits) to solve problems that would take traditional computers thousands of years to crack. Modern Era: Cloud, AI, and Beyond We use
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)
The journey didn’t start with electricity. Early "computers" like were entirely mechanical , using gears and levers to solve math problems.
