Network Topologies Quiz

In a star topology, what type of cable is usually used for wired connections?

• Ethernet cable

• Coaxial cable

• Fiber optic cable

• Twisted pair cable

What is the advantage of a star topology in terms of data transfer?

• Data is shared by many devices

• Data can be transmitted from different devices simultaneously

• The single cable is shared by many devices so there will be many ‘collisions’ of data if data is sent at the same time

• Fast data transfer to the hub as each wire isn’t shared with other computers

What is the disadvantage of a bus topology in terms of reliability?

• If the cable is damaged, the whole network fails

• If the central switch fails the whole network goes down

• Requires additional hardware such as the central switch and network cables

• Any device can view all data on the cable creating a security risk

What type of network topology involves nodes acting as routers to relay and spread data?

• Mesh topology

• Bus topology

• Star topology

• Ring topology

What is the advantage of a mesh network in terms of resilience?

• Data can be transmitted from different devices simultaneously

• No single point of failure – it is resilient

• Expansion and modification can be done without disrupting the network

• Can involve redundant connections

What is the disadvantage of a mesh network in terms of network maintenance?

• Expensive to install cabling if using wired connections

• Network maintenance and administration is difficult

• If the central switch fails the whole network goes down

• If the cable is damaged, the whole network fails

What type of network topology does the Internet use?

• Ring topology

• Star topology

• Bus topology

• Mesh topology

How might mesh principles affect wireless networks?

• As the distance between one node and another is halved, signal strength becomes four times stronger

• The more nodes that use the network, the more routes there are for data to travel through

• Only one node needs a wired Internet connection – no other cabling or infrastructure is required

• All of the above

What is the advantage of a bus topology in terms of cost?

• Any device can view all data on the cable creating a security risk

• Less cable so cheaper to install the network

• If the central switch fails the whole network goes down

• Requires additional hardware such as the central switch and network cables

What is the disadvantage of a star topology in terms of additional hardware?

• Requires additional hardware such as the central switch and network cables

• If the central switch fails the whole network goes down

• If the cable is damaged, the whole network fails

• Any device can view all data on the cable creating a security risk
