Physical Network Topology
21. List four disadvantages of a Mesh Topology.
-Difficult to implement -Difficult to administer -Difficult to troubleshoot -Expensive
20. List one advantage of a Mesh Topology.
-Extremely fault tolerant
14. List two advantages of a Linear Bus Topology.
-It's easy to connect a computer or peripheral to linear bus. -It requires less cable length than a star topology.
8. How many neighbors does each device in a ring topology have?
2
13. What is a "terminator"?
A special device the backbone cable stops at.
4. How is a Star Topology designed?
A star topology is designed with each node connected directly to a central network hub.
7. How does a ring topology connect devices?
It connects all devices in a circle with each device having exactly two neighbors.
2. What is Logical Topology?
It is the method used to pass information between workstations.
9. What is the advantage of a ring topology?
It minimizes the number of cables needed
1. What does physical topology of a network refer to?
It refers to the configuration of cables, computers, and other peripherals.
6. List three disadvantages of a star topology.
It requires more cable length than a linear topology. -If the hub fails, nodes attached are disabled. -It's more expensive than a linear bus because of the cost of the hub.
5. List three advantages of a star topology.
It's easy to install and wire. -There are no disruptions to the network when connecting or removing devices. -It's easy to detect faults and to remove parts.
19. Which topology connects each network device to many other network devices?
Mesh Topology
22. List the four things to consider when choosing a topology.
Money -Length of Cable Needed -Future Growth -Cable Type
16. The Tree Topology is a blend of what?
Star and bus networks
3. What are the five main types of Physical Network Topologies?
Star-Ring-Linear Bus- Tree- Mesh
15. List four disadvantages of a Linear Bus Topology.
The entire network shuts down if there is a break in the main cable. -The terminators are required at both ends of the backbone cable. -It's difficult to identify the problem if the entire network shuts down. It's not meant to be a stand-alone solution in a large building.
10. What is the disadvantage of a ring topology?
The failure of one device can take down the entire network.
18. List three disadvantages of a Tree Topology.
The overall length of each segment is limited by the type of cabling used. -If the backbone line breaks, the entire segment goes down. -It is more difficult to configure and wire than other topologies.
17. List two advantages of a Tree Topology.
Tree Topologies offer excellent flexibility for expansion. -There is point-to-point wiring for individual segments.
11. What does a linear bus topology use to connect all network devices?
common backbone cable.
12. What does the backbone cable function as?
shared communication link.
