Star topologies Flashcards
What is a star network?
Any device connected to a network is referred to as a node. All nodes are connected to the network either by wire or wirelessly.
What is a Network’s topology?
A network’s topology is the arrangement, or pattern, in which all nodes on a network are connected together.
What is Star Topologies ?
A network where each node is connected to a central switch
What is a Mesh Topologies?
A network where each node is directly connected to all other nodes.
How are Star topologies used?
Star topologies are used in many networks, large and small.
What is a switch in Star topology?
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.
How many Servers do Star Topology use?
Large networks using a star topology are usually controlled by one or more servers.
What does the client-server?
the client-server model usually uses a star topology.
What are the Advantages of Star Topology?
- each node is separately connected, therefore a failure of one node or its link, (transmission media), does not affect any other nodes
- new nodes can be added to the network simply by connecting them to the switch
- star networks tend to have higher performance as a message is passed on to its intended recipient only
What are disadvantagee of Star topology?
- the whole network fails if the switch fails as no node can communicate
- a wired star topology requires plenty of cable - in a large network this can be expensive
Where are Star topologies used in?
Star topologies tend to be found in large organisations, such as educational establishments and businesses, where high performance is a must.
Are Star topologies used in homes?
They are also found in home networks, especially those that are wireless. In this case, a router with a wireless access point (WAP) provides the central connection for all nodes.
