Core Networking Concepts (LAN vs WAN) for Tech+
Short answer
A network connects devices so they can share data and access services. LAN (Local Area Network) - Small/local: home, office, school building. WAN (Wide Area Network) - Connects LANs over larger geographic areas. - The internet is the most common WAN example. Basic idea: - Your devices talk to each other locally on a LAN. - A router typically connects your LAN to the WAN (internet). Common mistakes: - Thinking Wi-Fi is the internet. Wi-Fi is a local wireless connection method to your LAN. Out of scope: WAN carrier tech details.
