Lesson 3

Question 1

greek word for topology

Answer 1

topos

Question 2

what does topos mean

Answer 2

place

Question 3

this refers to the arrangement of elements of communication network

Answer 3

topology

Question 4

either the physical or logical structure of a network

Answer 4

topology

Question 5

network topology is also called as

Answer 5

network’s basic design

Question 6

schematic description of the arrangement of network elements

Answer 6

network topology

Question 7

arrangement or physical layout of the computers, cables and other components in the network

Answer 7

physical topology

Question 8

path that signals actually take around the network; flow of data through the network

Answer 8

logical topology

Question 9

often referred to as linear bus because all nodes are connected in a straight line

Answer 9

bus topologya

Question 10

all devices are connected to a central cable called the bus, trunk, or backbone

Answer 10

bus topology

Question 11

this is a component attached to each end of the cable to absorb free signals

Answer 11

terminator

Question 12

all network devices are connected into a single concentrating device called hub (indirect connections)

Answer 12

star topology

Question 13

all computers are connected to one another in a closed loop; the message flows in one direction only

Answer 13

ring topology

Question 14

the computer next to the source acts as a repeater (a device that boosts signal to travel further along the cable) and retransmits the signal to the next computer until the message reaches the computer with the exact destination address

Answer 14

ring topology

Question 15

true or false: no need for terminators in ring topology because there is no end to the ring

Answer 15

true

Question 16

what method is used by ring topology

Answer 16

token passing

Question 17

this is a special series of bits that is generated and is passed along the network until a computer that has a need to transmit data makes use of the token

Answer 17

token

Question 18

this requires complex, redundant links between each device in the network; can be full or partial

Answer 18

mesh topology

Question 19

has direct connection to all other devices in the network

Answer 19

full mesh topology

Question 20

has direct connection to other devices but not all

Answer 20

partial mesh topology

Question 21

formula for the total number of paths in a full mesh network

Answer 21

N = n(n-1)/2

Question 22

combines the characteristics of both the star and bus topologies

Answer 22

tree topology/star-bus topology

Question 23

uses several star topology networks connected through a single backbone

Answer 23

tree topology/star-bus topology

Question 24

may also be called star wired ring

Answer 24

star-ring topology

Question 25

combines multiple different topologies and the resulting topology doesn’t fall into basic topology definitions

Answer 25

hybrid topology

Question 26

combined characteristics of the topologies you are to connect

Answer 26

hybrid topology

Question 27

disadvantage: if the main cable breaks the entire network goes down

Answer 27

bus

Question 28

advantage: network expansion is easy
disadvantage: if the hub breaks down, the entire network goes down

Answer 28

star

Question 29

advantage: no danger of collision because only one packet of data can travel along the ring

Answer 29

ring

Question 30

advantage: immune to bottlenecks; redundant paths are available

Answer 30

mesh
