Pre-Internet Era (1950s–1960s)
J.C.R. Licklider envisioned a globally connected computer network, coining the idea of the "Intergalactic Computer Network," a precursor to today's internet. His ideas laid the groundwork for advancing technology and influenced a generation of computer scientists.
Driven by the Cold War, ARPA (now DARPA) was established in 1958 to create resilient communication systems. This era saw the invention of packet switching by Paul Baran and Donald Davies, revolutionizing how data was transmitted across networks. Additionally, developments in semiconductors laid a crucial foundation for faster data processing in the future.
Internet Era (1969–1989)
ARPANET, launched in 1969, was the first operational packet-switching network. It connected UCLA and Stanford, marking a significant milestone in networking history. The project demonstrated how multiple systems could share information seamlessly.
Key technologies like TCP/IP protocols, developed by Vint Cerf and Bob Kahn, enabled effective communication between diverse networks. By the late 1980s, these foundations paved the way for the development of the World Wide Web, which would connect billions of users globally in the decades to follow.
