Which of the following is not an accurate comparison of mesh networks and ring networks?

A
A mesh network connects all nodes to each other, while a ring network connects each node to the one nearest to it.
B
A ring network can be wider than most topologies but not as wide as a mesh network.
C
A mesh network is less stable than a ring network; that is why full mesh networks are rare.
D
A full mesh network is excellent but extremely expensive compared with a ring network.

C
a star topology
D
a mesh topology

You need an inexpensive, reliable network for about twenty-five computers, all of which will be in two rooms. It is important that the network not entirely depend on one hub or one node. However, nodes will regularly be added and removed from the network, so flexibility is essential. Which topology should you use?

A
bus
B
mesh
C
star
D
ring
5

Which statement below accurately compares ring networks and star networks?

A
Each node in a ring network makes a fresh copy of the packet when it comes through, so ring networks can be bigger than star networks or other topologies.
B
Ring networks have less redundancy than star networks, so they are more efficient.
C
Because of their configuration, star networks can be bigger than ring networks.
D
In a star network topology, when one node goes down, the whole network goes down, whereas a ring network would not go down.
6

A web topology is a network in which every node is connected to every other node.

A
True
B
False

Which of the following is NOT a network configuration?

A
