Wide Area Networks
IT Infrastructure and Networking
A Wide Area Network (WAN) is a telecommunications network that extends over a large geographic area, connecting multiple local area networks (LANs) across cities, countries, or continents, often using leased telecommunication lines, satellite links, or the internet. Network engineers and IT administrators design and manage WANs to enable organizations with multiple offices to share data, applications, and resources securely. Technologies like MPLS, VPNs, and SD-WAN are commonly used to optimize WAN performance and security.
