Why should I take this module?

Welcome to WAN Concepts!

As you know, local area networks are called LANs. The name implies that your LAN is local to you and your small home or office business. But what if your network is for a larger business, perhaps even a global enterprise? You cannot operate a large business with multiple sites without a wide area network, which is called a WAN. This module explains what WANs are and how they connect to the internet and also back to your LAN. Understanding the purpose and functions of WANs is foundational to your understanding of modern networks. So let’s jump in to WAN Concepts!
