In this type of network, a central controller forms the principal node, while the subsidiary nodes form the points of the star.
There are two types of server, the file server and the print server. The file server is used to store both programs and data. It acts as a massive hard drive on behalf of all the client terminals.
As the central machine controls the whole system, the whole system will be affected if it breaks down. Star topologies use more cabling than other topologies and this makes them more expensive. However, communication is fast because there is a direct path from the central controller to each terminal.
