questions.
Network Topology and Navigation Devices
Introduction: Just as buildings have different floor plans depending on their uses, networks have different
topologies delineating their layouts. Each topology meets the needs of a specific type of network. Various
navigation devices also are used with the active topologies to move data around a network.
Learn more about these topologies and the navigation devices used with them.
1) The different array of computers, peripherals, and media (cable) is called network ________.
A) topology
B) psychology
C) floor plan
D) navigation
2) In a ________, all devices are connected together through a central switch.
A) bus topology
B) ring topology
C) star topology
D) magnetic topology
3) The main advantage of a bus topology is that ________.
A) it is inexpensive
B) cable brakes are a problem
C) it transmits data to all devices in a small area capped by terminators
D) data collisions occur when two or more computers try to communicate at the same time
4) The purpose of a token ring is to ________.
A) prevent data collisions from occurring
B) make the network topology easy to implement
C) make the network topology inexpensive to implement
D) prevent the failure of one computer from bringing down the entire network
5) All of the following are network topologies EXCEPT:
A) bridge.
B) bus.
C) ring.
D) star.
6) All of the following are problems with the bus topology, EXCEPT:
A) cable breaks.
B) signal strength degrades over distance.
C) it is expensive.
D) performance is limited by only one computer communicating at a time.
7) In a ________ topology, all computers are connected in a line on a single cable.
A) star
B) ring
C) bus
D) routers
8) All are names for the topology where computers and peripherals are attached in a circle EXCEPT:
A) ring
B) loop
C) token ring
D) token circle
9) All of the following are navigation devices to move data around the network EXCEPT:
A) star.
B) switches.
C) bridges.
D) routers.

10) Connecting computers on a single line is called a(n) ________ topology.
11) Networks, like house floor plans, have different ________ delineating their layout.
12) Bus topology is most commonly used in ________ networks.
13) ________ are called smart hubs, retransmitting signals only to the devices that need to receive them.
14) ________ are a legacy general broadcast device.
15) A repeater moves data between two networks.
16) In a bus topology only the device for which a signal is intended can hear the sent data signal.
17) In the ring topology data flows around the circle in one direction only.
18) In ring topology a device grabs the token when it needs to send data.
19) The main advantage of a ring topology is that the failure of one computer does not affect the entire network.
20) Match the following terms to their meaning.
I.
topology
A.
devices do nothing to move data in the network
II. data collision
B.
computer attached to a network
III. node
C.
directs signals to the intended device
IV. passive network D.
arrangement of computers in a network
V. switch
E.
can occur when two computers transmit data at the same time
