A star topology is a type of computer network that USES the spoke hub distribution concept. In a star network, each host is connected to a central hub. In its most basic form, one single hub acts as a ROUTE for messages. The star network is one of the most common computer network architectures.

The following are some of the advantages of star topology:

• It is easy to analyze, set up, and modify.
• The nodes that have failed are the only ones that are affected. Other nodes are still up and running.
• Fast performance is attainable with a small number of nodes and little network traffic.
• In a Star topology, ADDING, removing, and transferring devices is straightforward.

The following are some of the disadvantages of star topology:

• If the Hub or CONCENTRATOR fails, the attached nodes are disabled.
• The cost of establishing a star topology is substantial.
• Heavy network traffic might cause buses to slow down dramatically.
• Performance is determined on the Hub's capacity.
• The network could be brought down by a faulty cable or a lack of suitable termination.
