WorksheetsUnderstanding Star and Mesh Networks
Total questions: 15
Worksheet time: 8mins
Which of the following best describes a star network topology?
All devices are connected in a closed loop
All devices are connected to a central switch or hub and radiate out from this
Each device is connected to every other device
Devices are connected in a straight line
In a mesh network, how are devices connected?
Each device is connected to a central hub only
Each device could be connected to every other device
Devices are connected in a ring
Devices are connected in pairs only
What is a main advantage of a star network?
If one cable fails, the whole network fails
Easy to add new devices
Uses the least amount of cable
No central point of failure
Which of the following is a disadvantage of a star network?
Difficult to add new devices
If the central hub fails, the whole network fails
High cost due to large amounts of cabling
Data collisions are common
What is a key advantage of a mesh network?
It is very cheap to set up
There is no single point of failure
It uses less cable than a star network
It is easy to manage
Which network topology is most likely to be used in a large office building where reliability is crucial?
Bus
Ring
Mesh
Star
In a star network, what happens if a single device (not the central hub) fails?
The whole network stops working
Only that device is affected
All devices lose connection to the network
Data is lost for all devices
Which of the following is a disadvantage of a mesh network?
It is difficult to add new devices
It could be expensive due to the amount of cabling required
It is not reliable
It is slow
Which device is typically at the centre of a star network?
Switch or hub (boo!)
Printer
Router
Server
Which network topology is most likely to be used for wireless networks in a large area, such as a university campus?
Star
Mesh
Bus
Ring
In a mesh network, what is the main reason for improved reliability?
Data travels in only one direction
There are alternative routes for data to travel
All devices are connected to a central hub
It uses less cable
Which of the following is NOT a feature of a star network?
Central device manages communication
Easy to isolate faults
Each device is connected to every other device
Performance is not affected by high traffic
What is a common use for mesh networks?
Home broadband connections
Large-scale wireless networks
Connecting a single printer to a computer
Small office networks
Which of the following statements about star and mesh networks is true?
Star networks are more expensive than mesh networks
Mesh networks are more reliable than star networks
Star networks have no central point of failure
Mesh networks are easier to set up than star networks
