What characterizes Wide-Area Networks (WANS)?

Wide-Area Networks (WANs) are specifically designed to connect devices that are located at significant distances from one another. This can include connecting multiple office locations within a large city, across states, or even across countries. WANs utilize various forms of communication technology, including telephone lines, satellite links, and radio waves, to facilitate data transmission over long distances. This characteristic makes option C the correct choice, as it accurately describes the fundamental purpose and functionality of WANs.

While the other options mention certain aspects related to network types, they do not accurately define WANs. For example, the idea of WANs covering a limited geographical area is contrary to their definition, as WANs are intended for wide coverage. Additionally, while fiber optic cables can be part of the WAN infrastructure, they are not exclusive to WANs and do not encompass all WAN connections. Finally, the assertion that WANs are consistently faster than local networks is misleading since speeds can vary greatly depending on technology used and distance, and local area networks (LANs) are typically faster due to their shorter distances and less congestion.
