What is one primary function of a Wide Area Network (WAN)?

A Wide Area Network (WAN) primarily functions to link multiple smaller networks across extensive geographical distances. This allows various local area networks (LANs) or other networks to communicate with each other, enabling data sharing and resource access regardless of the physical distance separating them.

WANs are essential for large organizations or institutions that operate across different locations, as they facilitate centralized access to information and applications, promote collaboration, and ensure connectivity across dispersed sites.

While connecting local devices within a home is characteristic of local area networks (LANs), and providing internet access to users typically involves a different scope that may leverage WAN technology, the fundamental role of a WAN lies in bridging diverse and distant networks together. Increasing processing speed on individual computers is unrelated to the purpose of a WAN, which is centered on connectivity rather than enhancing individual machine performance.
