Topologies

Question 1

what’s a topology?

Answer 1

The layout of how a network communicates with different devices.

Question 2

The layout of how a network communicates with different devices is called a _________.

Answer 2

topology

Question 3

the most common topology is the ____ topology.

Answer 3

star

Question 4

what’s a star topology?

Answer 4

a network topology where all network components are connected to a central wiring point.

Question 5

In a star topology, All data on a star network passes through the _______ _____ before continuing to its destination.

Answer 5

central point

Question 6

Major benefit of star topology?

Answer 6

if one computer 🖥️ failed, or if there was a break in the cable, the other computers would not be affected because each computer has their own cable connection.

Question 7

Disadvantage of star topology?

Answer 7

if the central hub or switch fails, then all the computers 🖥️ on that central point would be affected. And this is called a single point of failure. If this happens, the entire network goes down.

Question 8

What’s a bus topology?

Answer 8

network setup where each of the computers and network devices are connected to a single cable or backbone.

Question 9

Backbone is a ?

Answer 9

Coaxial cable

Question 10

In bus topology, computers connect to the backbone using special connectors called ___, which are also known as _ ___________.

Answer 10

BNC, T-connectors

Question 11

Major Benefit of the Bus Topology?

Answer 11

fairly cheap and easy to implement/execute.

Question 12

Disadvantage of Bus Topology

Answer 12

it requires that the cable be terminated at both ends using terminators.

Question 13

If a computer is removed or added or if the terminators are loose or missing, then the cable would be open and data would bounce back. This is known as

Answer 13

signal reflection

Question 14

What’s a ring topology?

Answer 14

network configuration, where each computer is connected to each other in the shape of a closed loop or ring.

Question 15

in ring topology, every computer on the ring has exactly two neighbors for ____________ purposes.

Answer 15

communication

Question 16

in ring topology, each data packet is sent around the ring until it reaches ___ ______ ___________.

Answer 16

its final destination

Question 17

Major benefit of Ring Topology 💍

Answer 17

easy to install and easy to troubleshoot.

Question 18

Disadvantage of Ring Topology 💍

Answer 18

if just one of these computers goes down, or if there was a single break in the cable, then all data flow would be disrupted.

Question 19

What’s a mesh topology?

Answer 19

network configuration, where each computer on the network connects to every other computer on the network.

Question 20

In a mesh topology, by having so many connections, it handles ________ very well.

Answer 20

failure

Question 21

Mesh topologies are rarely used on _____, because it’s expensive.

Answer 21

LANs

Question 22

Mesh topologies are mainly used on _____, like the internet.

Answer 22

WANs

Question 23

the ________ is a perfect example of a mesh topology.

Answer 23

Internet

Question 24

Major benefit of a Mesh Topology?

Answer 24

it creates a high redundancy level. Because if one or more connections fail, the computers would still be able to communicate with each other

Question 25

What are hybrid topologies?

Answer 25

a combination of different topologies.

Question 26

most common forms of hybrid topologies include? (include 2)

Answer 26

star-bus network
star-ring network

Question 27

what’s a star-bus network?

Answer 27

two or more star topologies are linked together using a single bus connection.

Question 28

what’s a star-ring network?

Answer 28

two or more star topologies are linked together to form a large ring network.

Question 29

What’s the simplest form of topology there is?

Answer 29

point-to-point topology

Question 30

what’s a point-to-point topology?

Answer 30

two hosts that are directly connected to each other using a single cable.

Question 31

what’s a client-server topology?

Answer 31

A client server topology is where clients connect directly to a centralized dedicated server to access resources rather than connecting to each other.

Question 32

why do a lot of businesses use the client-server topology?

Answer 32

putting the resources on just one machine, is a lot less work than putting the data on multiple clients. It makes the administration a lot simpler.

Question 33

what’s a point-to-multipoint topology?

Answer 33

a network architecture that is commonly used in wireless outdoor networks.

Question 34

What’s a peer-to-peer topology?

Answer 34

A peer to peer topology is where all the clients on the network talk to every other client on the network to share their resources with each other.

Question 35

In a peer-to-peer topology, there is no centralized server that the clients connect to, they all just connect to ____ _____.

Answer 35

each, other

Question 36

where would you typically find peer-to-peer topologies? (include 2)

Answer 36

homes and small businesses.
