Workstations can be easily added to a network employing a star topology. If one run of networking media is broken or shorted, then only the device attached at that point is out of commission, the rest of the LAN will remain functional. In short, a star topology means greater reliability. In some ways a star topology's advantages can also be considered disadvantages. For example, while limiting one device per run of networking media can make diagnosis of problems easier, it also increases the amount of networking media required, which adds to the setup costs.
Every outlet is independently and directly wired to the patch panel.
This figure includes the 90 meters for the horizontal cabling, the 3 meters for the patch cords, and the 6 meters for the jumpers at the horizontal cross-connect. Horizontal cabling runs in a star topology radiate out from the hub, much like the spokes of a wheel. For example, envision a building where the dimensions are 200 m x 200 m. As shown, they are not part of the local area network. So users at these workstations wanting to send, share, and receive files, would have to use sneakernet.
