    - Now that we've talked about WANs and MANs, let's talk about networks on a little bit smaller scale. Let's go ahead and talk about LANs, WLANs, and PANs. A LAN stands for a local area network, and is generally a network that is limited to a very small size, or very small geographical area. It's very common for LAN to be as small as a single room or they can even be as big as an entire building. Once in a while, you may even run across a LAN that spans several buildings that are close together. If the buildings are far apart, for example, different parts of town, or something like that, at that point we no longer have a LAN, but we have a MAN, like we talked about previously. The TIA/EIA 568-C standard defines the characteristics that make up a local area or LAN network. LANs will usually use twisted pair cabling to connect the nodes, or computers, to a central device. If you're setting up a new LAN in a building that's just being constructed, or possibly you're putting up a LAN in a…
