Mini Test 2 (Network Topologies)

What is meant by the term network topology?

• The arrangement or pattern in which all nodes on a network are connected together

• The transmission method used, which will be either wired or wireless

• The security arrangement of the network

• The maximum number of devices on the network

Which of the following are the most common topologies used today.

• Star topology

• Bus topology

• Ring topology

• Mesh topology

Home networks are usually arranged in which topology?

• Star topology

• Ring topology

• Bus topology

• Mesh topology

Which of the following are advantages of the star topology?

• A failure of one node or its connection does not affect any other nodes

• Communications should always get through as there are many possible routes

• New nodes can be added to the network easily by connecting them to the switch

• Multiple connections mean that each node can transmit to and receive from more than one node at the same time

Which of the following are disadvantages of the star topology?

• The whole network is affected if the central point fails because no node can communicate

• It is expensive to implement because each device connects directly to every other device in the network

• Data collisions never occur because the devices are connected by a central switch

• Wired networks can be expensive if you need to connect lots of devices

Which of the following are advantages of the mesh topology?

• Multiple connections mean that a data collision will never occur

• Multiple connections mean that each node can transmit to and receive from more than one node at the same time

• As there are multiple connections and no central node, a node should not become isolated

• Communications should always get through as there are many possible routes

Which of the following are disadvantages of the mesh topology?

• The whole network is affected if the central point fails because no node can communicate

• Many connections would be expensive to implement

• Many connections would mean a lot more maintenance is needed

• Mesh topologies are only suitable for Local Area Networks

What is the purpose of a switch in a star topology?

• The switch acts as a central point through which all communications are passed.

• The switch stores all of the files and documents of the users of the network

• The switch checks that each user is authentic by checking their username and password

• The switch is the pattern or arrangement of the nodes in the network

In a FULL mesh topology...

• Each node is directly connected to every other node

• Not all nodes are connected directly to each other

• There is a central connection point

• A node is capable of sending communications to only one device

In a PARTIAL mesh topology...

• There is a central connection point

• Each node is directly connected to every other node

• Each device can transmit data directly to every device in the network

• Not all nodes are connected directly to each other
