Topology Notes
List four disadvantages of a Linear Bus Topology.
4 disadvantages for a linear bus topology is the entire network shuts down if there is a break in the main cable, terminators are required at both ends of the backbone cables, it's difficult to identify the problem if the entire network shuts down, and it's not meant to be a stand-alone solution in a large building.
What does a linear bus topology use to connect all network devices?
A linear bus topology uses a common background cable to connect all network devices.
How does a ring topology connect devices?
A ring topology connects to devices in a circle.
What is a "terminator"?
A terminator is a special device that is the end of a network.
What does physical topology of a network refer to?
Physical topology of a network is referred to the configuration of computers, cables, and other peripherals.
How many neighbors does each device in a ring topology have?
Ring topology devices have 2 neighbors.
How is a Star Topology designed?
Star topology is designed with each node connected directly to a central network hub.
What are the five main types of Physical Network Topologies?
The 5 main physical Network topologies are star, ring, linear bus, tree, and mush.
The Tree Topology is a blend of what?
The Tree Topology is a blend of star and bus networks.
What is the advantage of a ring topology?
The advantage for ring topology is it minimizes the number of cables needed.
List three disadvantages of a star topology.
Three disadvantages for star topology is: It requires more cable length than a linear topology, If the hub fails, nodes attached are disabled, and it's more expensive than a linear bus because of the cost of the hub.
List three disadvantages of a Tree Topology.
Three disadvantages of a tree topology is its overall length of each segment is limited by the type of cabling used, If the backbone line breaks, the entire segment goes down, and it's more difficult to configure and wire than other topologies.
List two advantages of a Linear Bus Topology.
Two advantages for a linear bus topology are its Easy to connect a computer or peripheral to linear bus and it requires less cable length than a star topology.
List two advantages of a Tree Topology.
Two advantages of a tree topology is tree topologies offer excellent flexibility for expansion and its point-to-point wiring for individual segments.
what is the meaning of branch?
the thing that holds everything together.
List one advantage of a Mesh Topology.
One advantage of a Mesh Topology is it's extremely fault tolerant.
List four disadvantages of a Mesh Topology.
Four disadvantages of a Mesh Topology are it's difficult to implement, it's difficult to administer, it's difficult to troubleshoot, and it's expensive.
What is Logical Topology?
Logical topology is the method used to pass info between workstations.
What is the disadvantage of a ring topology?
The disadvantage for ring topology is the failure of one device can take down the entire network.
List the four things to consider when choosing a topology.
The four things to consider when choosing a topology is a linear bus network may be the least expensive way to install a network. The linear bus network uses shorter lengths of cable. With a star topology, expanding a network is easily done by adding another concentrator. The most common cable in schools is unshielded twisted pair, which is most often used with star topologies.
Which topology connects each network device to many other network devices?
The topology that connects each network device to many other network devices is Mesh.
List three advantages of a star topology.
Three advantages for star topology is: It easy to install and wire, there's no disruptions to the network when connecting or removing devices, and it's easy to detect faults and to move parts.
