Question
Which early network, developed in 1969, laid the groundwork for the internet?
A. PREINTERNET
B. ARPANET
C. OURNET
Answer
B. ARPANET
Explanation
The ARPANET (Advanced Research Projects Agency Network) was the pioneering computer network established in 1969 under the U.S. Department of Defense. It introduced revolutionary concepts like packet switching, which enabled data to be transmitted efficiently across distributed networks. Initially connecting four nodes—UCLA, Stanford Research Institute, UC Santa Barbara, and the University of Utah—ARPANET demonstrated the feasibility of networking disparate computer systems.
ARPANET’s development laid the foundation for critical technologies such as email (introduced in 1971) and the TCP/IP protocols that ultimately became the backbone of the modern internet. While it was initially designed for military and academic purposes, ARPANET evolved into a global communication tool, culminating in its transition into the larger framework of the internet by the 1980s and 1990s.
