The internal network, and therefore the LAN, exists to link all of the PCs, laptops, servers, printers, and anything else that might be useful for a computer to talk to. Most LANs have a cable running from every computer to a wall jack. The wall jack is connected to a very similar type of cable that runs to a patch panel in a wiring closet. A patch panel is simply a bank of cable ports that allows all of the cables coming from each wall jack to be connected to the LAN if desired. Any active wall jack must have the corresponding port in the patch panel connected to a switch in the wiring closet. A wiring closet is a centralized room where these cables end. It is common for there to be many wiring closets in a building. The standard is that these wiring closets not actually be used for anything
