Computer Networks: Crash Course Computer Science

The video explores the evolution of computer networks, starting from isolated computers to the development of early networks in the 1950s and 60s. It discusses the introduction of Ethernet, the management of data collisions, and the concept of exponential backoff. The video also covers network construction, routing, and the transition to packet switching, highlighting the significance of ARPANET as a precursor to the modern internet.
