ABSTRACT
Essentially a network of networks, the Internet permits computers across the globe to communicate with each other. It evolved out of the Advanced Research Projects Network (ARPAnet) developed by the United States Department of Defense in the late 1960s (Lowe et al., 1996). ARPAnet was built with the intention of developing computer networks that would be capable of surviving nuclear war. The challenges at that time were to develop methods for sharing information across diverse sites and to keep these connections operational even if a disruption occurred at individual sites.
