Exploring the Evolution of Computer Networks

The video explores the evolution of computer networks, starting from early isolated computers to the development of Local Area Networks (LANs) and Ethernet. It explains how Ethernet uses MAC addresses and CSMA to manage data transmission and handle collisions through Exponential Backoff. The video also covers network switches, routing, and the differences between circuit and message switching. Finally, it introduces packet switching, the ARPANET, and the growth of the internet, highlighting the decentralized nature of modern networks.
