Why is star topology the most popular?
Star networksAny device connected to a networkis referred to as a node. All nodes are connected to the network either by wire or wirelessly. Show A network's topologyis the arrangement, or pattern, in which all nodes on a network are connected together. There are several common topologies that are in use, but today the most common topologies are:
Star topologies are used in many networks, large and small. In a star topology all nodes indirectly connect to each other through one or more switches. The switch acts as a central point through which all communications are passed. Large networks using a star topology are usually controlled by one or more servers. Hence, the client-servermodel usually uses a star topology. However, peer-to-peernetworks can also have a star topology. Even though no single computer controls the network, all communications still pass through the central switch. Advantages and disadvantages of using a star topologyHaving nodes arranged in a star topology brings some benefits:
However, star topologies also have their disadvantages:
Star topologies in useStar topologies tend to be found in large organisations, such as educational establishments and businesses, where high performance is a must. They are also found in home networks, especially those that are wireless. In this case, a routerwith a wireless access point (WAP)provides the central connection for all nodes. |
