The journey didn’t start with electricity. Early "computers" like were entirely mechanical , using gears and levers to solve math problems.

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)

Transistors allowed engineers to pack more power into smaller spaces.

The evolution of computers is a story of making things . We’ve moved from room-sized calculators to wearable tech that is millions of times more powerful.
