Network Topologies

7.How does a ring topology connect devices?

A Ring Topology connects all devices in a circle with each device having exactly two neighbors.

11.What does a linear bus topology use to connect all network devices?

A linear Bus Topology uses a common backbone cable to connect all network devices. The backbone cable functions as a shared communication link, which carries network data. The backbone cable stops at each end of the network with a special device called a "terminator"

22.List the four things to consider when choosing a topology.

A linear bus network may be the least expensive way to install a network; you do have to purchase the concentrators. The linear bus network uses shorter lengths of cable. The linear bus network uses shorter lengths of cable. The most common cable in schools is unshielded twisted pair, which is most often used with star topologies.

19.Which topology connects each network device to many other network devices?

A mesh topology connects each network device to many other network devices. Data traveling on a mesh network can take any of several possible paths from its source to its destination. These redundant data pathways make a mesh network very robust.

12.What does the backbone cable function as?

A shared communication link.

4.How is a Star Topology designed?

A star topology is designed with each node (file server, workstation and peripheral) connected directly to a central network hub.

Question

Answer

18.List three disadvantages of a Tree Topology.

Overall length of each segment is limited by the type of cabling used.If the backbone line breaks, the entire segment goes down.More difficult to configure and wire than other topologies.

6.List three disadvantages of a star topology.

Requires more cable length than a linear topology. If the hub fails, nodes attached are disabled. More expensive than a linear bus because of the cost of the hub.

3.What are the five main types of Physical Network Topologies?

Star, Ring, linear Bus, Tree, Mesh

13.What is a "terminator"?

The backbone cable stops at each end of the network with a special device called a "Terminator".

14.List two advantages of a Linear Bus Topology.

Easy to connect a computer or peripheral to linear bus. Requires less cable length than a star topology.

5.List three advantages of a star topology.

Easy to install and wire. No disruptions to the network when connecting or removing devices. Easy to detect faults and to remove parts.

15.List four disadvantages of a Linear Bus Topology.

Entire network shuts down if there is a break in the main cable.

10.What is the disadvantage of a ring topology?

Failure of one device can take down the entire network.

2.What is Logical Topology?

It is the method used to pass information between workstations.

1.What does physical topology of a network refer to?

It refers to the configuration of cables, computers, and other peripherals.

9.What is the advantage of a ring topology?

Minimizes the number of cable needed.

8.How many neighbors does each device in a ring topology have?

They have exactly two neighbors.
