What is a Wide Area Network (WAN)?

A Wide Area Network (WAN) refers to a type of computer network that spans a large geographical area, often connecting multiple local area networks (LANs) or data centers. WANs are used to transmit data, applications, and services over long distances, typically using various technologies like leased lines, satellites, or the internet. They facilitate communication between geographically dispersed locations, making them essential for global connectivity and remote access.
