TED-Ed: The hidden network that makes the internet possible - Sajan Saini

The video explores the evolution of data transmission from copper wires to fiber optics, highlighting the advantages of fiber optics in terms of speed and efficiency. It explains the principle of total internal reflection, which allows light to travel through glass fibers. The video also discusses the challenges of cloud computing and bandwidth demand, and introduces integrated photonics as a solution. This technology uses silicon wires and photonic chips to enhance data transmission and overcome wireless limitations, paving the way for faster and more efficient connectivity.
