Star topology is a network topology where each individual piece of a network is attached to a central node (often called a hub or switch). The attachment of these network pieces to the central component is visually represented in a form similar to a star. Star topology is also known as a star network.
Advantages and disadvantages of a star network
Advantages
(1) Very reliable – if one cable or device fails then all the others will continue to work.
(2) high performing as no data collisions can occur
Disadvantages
(1) Expensive to install as this type of network uses the most cable (network cable is expensive)
(2) Extra hardware required (hubs or switches) which adds to cost
(3) if a hub or switch fails all the devices connected to it will have no network connection
