A network’s topology has a significant effect on its performance and growth potential.

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.

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

The mesh network topology is the most expensive one.

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

In a physical ring topology, signals typically travel in both directions around the ring.

The ring-based technologies implemented as a physical star include ____ and token ring.

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

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.

A(n) ____ attached to each end of a cable prevents signals from bouncing on a physical bus.

On a bus network, open ends in a cable segment must be terminated to prevent ____.

A physical bus topology is almost always implemented as a logical ____ topology.

All computers, no matter what their topology, communicate in the same way: They address data to one or more computers and then transmit that data across the cable in the form of ____.

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 physical ring is a(n) ____ topology.

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

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

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

When wireless devices are configured to use an access point, they are said to be in ____ mode.

In most situations, wireless LANs use a central device, called a(n) ____, to control communications.

A ____ network topology is the most fault tolerant one.

The mesh topology formula for determining how many connections are needed for the number of nodes on a network, with n representing the number of nodes on the network is: ____.

The majority of hubs installed in networks today are ____ hubs.

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

A hub-based bus topology should be considered if a small network (____ or fewer computers) is being constructed and keeping costs down is paramount.

A hub-based ____ topology might be considered if a few computers are being added to an existing network, and the new computers are grouped in a somewhat remote location.

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

The logical topologies that dominate LANs include bus, ring, and ____________________.

A logical bus topology is still in use on some physical topologies, in particular a(n) ____________________.

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.

FDDI stands for ___________________________________.

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

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.
