Understanding Internet Communication

The video tutorial by Tess Winlock, a Google software engineer, explains how the internet functions as a physical system to transfer information. It covers the basics of binary information, how bits are sent using electricity, light, and radio waves, and the concepts of bandwidth and latency. The tutorial also discusses long-distance communication using fiber optics and the role of wireless technology in making the internet mobile. Despite advancements, the internet remains a fragile system reliant on both wired and wireless methods.
