A disadvantage of the ring topology lies in its inability to share network resources fairly.

Because of the ____ phenomenon, a method to ensure that all signals stop when they reach the end of any segment in a bus topology must be devised.

In the simplest wireless configuration, two computers can communicate directly with one another in a(n) ____ topology.

The first step in any network design is to evaluate the underlying requirements.

It's important to note that a bus topology is a(n)____________________ topology; this means that computers on the bus only listen for data being sent; they aren't responsible for moving data from one computer to the next.

In a(n) ____ hub, such as a patch panel or punchdown block, the signal passes through the hub without any amplification or regeneration.

Generally, active hubs have many ports-eight or more-and so are sometimes called ____________________ repeaters or repeating hubs.

A central device, usually a(n) ____, sits in the middle of the extended star topology.

All network designs today are based on ____ simple physical topologies.

The mesh network topology is the most expensive one.

Signals on a bus generated by the signal bounce effect significantly reduce the performance, but do not render computer communication on the bus network unworkable.

At the center of a logical bus implemented as a physical star is a device called a(n) ____.

Discuss the advantages and disadvantages of a physical star topology.

FDDI stands for ___________________________________.

In a(n) ____ topology network, computers and other devices attached to the network regenerate signals and are responsible for moving data through the network.

A(n)____________________ topology might be the only reasonable topology choice in an environment that's not conducive to running cables, such as warehouses and old or historic buildings.

Match each term with the correct statement below.

Describe how the logical ring topology works.
