The ARPANET: A Digital Genesis

This book explores the foundational history of the internet through the story of ARPANET. Born from Cold War-era innovation and visionary thinking, ARPANET was the world’s first operational packet-switching network and the direct precursor to today's internet. The book chronicles key milestones—from Licklider's "Intergalactic Computer Network" concept and Kleinrock's packet-switching breakthrough to the first message sent in 1969 and the adoption of TCP/IP in 1983. It highlights how ARPANET evolved from a military-academic project into a global communication infrastructure, enabling email, resource sharing, and the interconnected digital world we know today.
