How does the Internet work? Where is the internet?

The internet, a crucial part of modern life, is not located in a single place but is instead a vast network of servers spread across the globe. Created in 1969 by the U.S. Defense Department's DARPA, the internet was designed to be resilient, ensuring communication could continue even if parts of the network were destroyed. Today, approximately 75 million servers house the content of the internet, connected by fiber optic cables and exchange points in major cities.

When users access websites, their browsers locate the corresponding servers using unique IP addresses, which are numerical identifiers for each domain. The content is then rendered in a user-friendly format through HTML. Major tech companies like Microsoft, Google, Apple, and Mozilla play significant roles in shaping the standards of the web, as they produce the most widely used browsers.

Interestingly, the internet has a measurable weight, estimated by Google to be around 0.2 millionths of an ounce, equivalent to the weight of a grain of sand. This weight represents the trillions of electronic signals that make up the digital world, highlighting the intangible yet impactful nature of the internet in everyday life.
