In a star topology only the failed system would have a problem, unless the device was the network connectivity device (on a LAN).
In a WAN, if the building was connected through the central building and the central building had a problem then all buildings would be affected. If it isn't the central connection point then only the building with the problem would be affected.

Star topology.
It is a Client/Server system. The most common topology for this is a Star topology.
The most common LAN topology is that of a "star." In a star topology, each computer, or "node", is connected to a central hub. This is more reliable than a more classical "ring" topology, because a node failing will not bring down the entire network. A bus topology is arguably more reliable, but has poorer performance.
The "star" topology is the most common.
Star topology
Star Topology, where Hubs can act as repeaters.
Star topology is one of the oldest topology
bus topology.
Scalability and reliabillty of star topology makes it the best, easy to remove or add a device.
There are number of LAN technologies and each technology is classified into a category according to its topology , two such topologies are star and ring topology. In star topology ,The hub accepts data from a sender and delivers it to receiver, there is no security in star topology . In Ring topology Computers are connected in a circle- the first computer is cabled with the second computer.
