Wide Area Network (WAN)

A Wide Area Network encompasses large-scale network infrastructure that connects geographically dispersed networks across cities, countries, or continents. WANs operate through a combination of public and private communication links, often utilizing telecommunications infrastructure. The Internet itself represents the largest public WAN, while organizations may maintain private WANs for secure internal communications.

WANs typically operate at lower data rates compared to LANs due to the challenges of long-distance data transmission. They employ sophisticated routing mechanisms to manage complex traffic patterns and ensure reliable data delivery across vast distances.
