WAN wide area connectivity – UGC NET Question

A wide area network connects devices and smaller networks across cities, countries or continents, typically using leased telephone lines, satellite links or the internet. The defining characteristic of a WAN is its broad geographical span. Many universities link their campuses with WANs. Hence, the correct term for the type of network described is wide area network.

Option A:
Option A, local area network, is confined to small areas such as a building and cannot accurately represent connections over large distances.

Option B:
Option B, metropolitan area network, covers a city or metropolitan region, which is intermediate between LAN and WAN and not necessarily national or global.

Option C:
Option C is correct because wide area network is the standard term in networking classifications for long distance interconnection of devices and LANs.

Option D:
Option D, storage area network, refers to a specialised high speed network for storage devices in a data centre and does not primarily describe geographical spread.
