Why were WANs first studied?
What will be an ideal response?
WANs were first studied in the late 1960s and early 1970s for reasons of reliability and fault tolerance. The U.S. military was interested in communication systems that could survive and function even if some of their components were destroyed, as might happen in a time of war or civil unrest. Their research ultimately led to the creation of the Internet.
