The Tiny Envelopes Powering Your Internet
Every piece of data you send online is chopped into tiny packages called Ethernet frames. These frames act like digital envelopes that carry your information across physical cables to its destination.
Without these standardized containers, your computer would have no way to organize or send data across a network. Each frame wraps your digital messages in special headers that act like shipping labels, ensuring the data finds the right device. It is a constant, invisible relay race happening millions of times per second. This simple delivery system is the hidden backbone that allows the entire global internet to function.
