Which statement is true about the development of the Internet?

The statement regarding Paul Baran developing packet switching is accurate because he was instrumental in the conceptualization and design of the packet switching technique, which allows for data to be broken into packets before being transmitted over networks. This innovation was crucial for the development of the Internet as it enabled efficient and reliable data communications.

Packet switching contrasts with traditional circuit-switched communication, where a dedicated channel is established for the duration of a transmission. The ability to route packets independently through a network greatly enhanced flexibility, speed, and the robustness of communication systems, laying the groundwork for the Internet as we know it today.

The other statements do not accurately reflect key historical facts. For instance, Tim Berners-Lee is known for inventing the World Wide Web, not for developing packet switching. Furthermore, while government agencies played a significant role, many other organizations, universities, and private companies were also involved in the Internet's development. Lastly, ARPAnet was not limited to one university's network; it connected multiple universities and research institutions, facilitating the early stages of Internet connectivity.
