They developed TCP/IP (Transmission Control Protocol/Internet Protocol). TCP handles data assembly/disassembly, while IP ensures packets reach the correct address.
In the early 1960s, researchers like Leonard Kleinrock , Paul Baran , and Donald Davies independently developed "packet switching". This method breaks data into small "packets" that can take different routes to a destination and reassemble upon arrival, making networks more resilient than traditional telephone lines. 2.

As more independent networks emerged, they were often incompatible. and Bob Kahn , often called the "Fathers of the Internet," solved this by designing a universal language. researchers like Leonard Kleinrock
