Network Topologies
Which topology connects each network device to many other network devices?
A mesh topology.
What is the advantage of a ring topology?
Minimizes the number of cables needed.
List the four things to consider when choosing a topology.
Money, Length of Cable Needed, Future Growth, and Cable Type.
List three disadvantages of a Tree Topology.
1. Overall length of each segment is limited by the type of cabling used. 2. If the backbone line breaks, the entire segment goes down. 3. More difficult to configure and wire than other topologies.
List three disadvantages of a star topology.
1. Requires more cable length than a linear topology. 2. If the hub fails, nodes attached are disabled. 3. More expensive than a linear bus because of the cost of a hub.
List two advantages of a Tree Topology.
1. Tree topologies offer excellent flexibility for expansion for example; a single link to the backbone cable can add an entire group of star-configured devices. 2. Point-to-point wiring for individual segments.
List four disadvantages of a Mesh Topology.
1. Difficult to implement. 2. Difficult to administer. 3. Difficult to troubleshoot. 4. Expensive.
List two advantages of a Linear Bus Topology.
1. Easy to connect a computer or peripheral to linear bus. 2. Requires less cable length than a star topology.
List three advantages of a star topology.
1. Easy to install and wire. 2. No disruptions to the network when connecting or removing devices. 3. Easy to detect faults and to remove parts.
List four disadvantages of a Linear Bus Topology.
1. Entire network shuts down if there is a break in the main cable. 2. Terminators are required at both ends of the backbone cable. 3. Difficult to identify the problem if the entire network shuts down. 4. Not meant to be a stand-alone solution in a large building.
What does the backbone cable function as?
A shared communication link, which carries network data.
The Tree Topology is a blend of what?
A star and a bus network.
How does a ring topology connect devices?
Connects all devices in a circle or ring.
How many neighbors does each device in a ring topology have?
Exactly 2 neighbors
List one advantage of a Mesh Topology.
Extremely fault tolerant.
What is the disadvantage of a ring topology?
Failure of one device can take down the entire network.
What are the five main types of Physical Network Topologies?
Star, Ring, Linear Bus, Tree, and Mesh.
What does physical topology of a network refer to?
The configuration of cables, computers, and other peripherals.
What is a "terminator"?
The device at each end of the network that stops the backbone cable.
What is Logical Topology?
The method used to pass information between workstations.
What does a linear bus topology use to connect all network devices?
Uses a common backbone cable to connect all network devices.
How is a Star Topology designed?
With each node (file server, workstation and peripheral) connected directly to a central network hub.
