Transistors: The Tiny Switches That Power Modern Life

Transistors are microscopic switches that control the flow of electricity.
Invented in 1947, they replaced bulky vacuum tubes in electronics.
They can amplify signals or act as on/off digital switches.
Billions of transistors fit onto a single microchip today.
Their switching speed enables modern computing and high-speed internet.
Field-effect transistors (FETs) dominate microchip design.
Moore’s Law predicted the doubling of transistors on chips every two years.
Smartphones, laptops, and cars all depend on transistor-packed circuits.
Transistors consume little power, making portable electronics possible.
They are the foundation of the digital age, from AI to space travel.
