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

A common backbone cable.

What does the backbone cable function as?

A shared communication link, which carries network data.

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, and it's more difficult to configure and wire than other topologies.

List three disadvantages of a star topology.

Requires more cable length than 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.

The tree topology is a blend of what?

Star and bus networks.

What are the five main types of Physical Network Topologies?

Star, Ring, Linear Bus, Tree, and Mesh.

List two advantages of a tree topology.

Tree topologies offer excellent flexibility for expansion, and point-to-point wiring for individual segments.

How many neighbors does a ring topology have?

Two.

How is a star topology designed?

With each node connected directly to a central network hub.

List two advantages of a linear bus topology.

Easy to connect to a computer of peripheral and requires less cable length than a star topology.

List three advantages of a star topology.

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

What is the disadvantage of a ring topology?

Failure of one device can take down the entire network.

How does a ring topology connect devices?

In a circle.

List four disadvantages of a mesh topology.

It's difficult to implement, administer, troubleshoot, and it's expensive.

List one advantage of a mesh topology.

It's extremely fault tolerant.

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

Mesh

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.

What does physical topology of a network refer to?

The configuration of cables, computers, and other peripherals.

What is a "terminator"?

The device that stops the backbone cable at each end of the network.

List four disadvantages of a linear bus topology.

The entire network shuts down if there is a break in the main cable, terminators are required at both ends of the backbone cable, it's difficult to identify the problem if the network shuts down, and it's not meant to be a stand-alone solution in a large building.

What is Logical Topology?

The method used to pass information between workstations.
