3.Network Topologies

What is a network topology?

• The layout of computer systems on a network

• The speed of data transfer on a network

• The security measures implemented on a network

• The number of computer systems on a network

Which network topology is easy to implement and add more computer systems to?

• Bus network

• Ring network

• Star network

• Mesh network

What is the main disadvantage of a bus network?

• Difficult to troubleshoot

• Limited cable length and number of stations

• Low security

• Data collisions are more likely

In which network topology does data travel in one direction only?

• Bus network

• Ring network

• Star network

• Mesh network

What is the advantage of a ring network?

• Data is quickly transferred without a bottleneck

• Easy to set up

• Possible to add more computer systems without taking the network down

• Better security

Which network topology requires extra hardware, such as a hub?

• Bus network

• Ring network

• Star network

• Mesh network

What is the advantage of a star network?

• Good performance/fast network speed

• Minimal network collisions

• Better security

• All of the above

What is the main disadvantage of a star network?

• Expensive to install – more cabling required

• Extra hardware required, such as a hub

• Difficult to troubleshoot

• Limited cable length and number of stations

Which network topology prevents network collisions?

• Bus network

• Ring network

• Star network

• Mesh network

What is the purpose of terminators in a bus network?

• To ensure data is transferred quickly

• To prevent network collisions

• To add more computer systems to the network

• To troubleshoot the network
