A topology is a physical structure of a network. Star topology is one the most common topology in the LAN. Other topologies are Ring topology, Bus topology and Mix topology.
In start topology every computer is connected to a central point. That central point may be a HUB or a switch. The media used in this topology is twisted pair cable. The communication devices used is a LAN card. Every computer must have a LAN card and a twisted pair cable. One end of the cable is plugged in LAN card and the other is connected with the HUB or a switch. If we have a domain then the Server should also be connected with the HUB or switch. Every source, which we may share, should be connected to one of the computers (e.g. printer).
Star topology is considered one the best topology. The advantage is that if any computer is not working or any cable is not working then the whole network will not be affected. But the disadvantage is that it is expensive form of network as every computer required a separate cable to form the network. The other disadvantage is that if the HUB is not working, the whole network will be dumb.
