Which of the following best describes a star topology?

• All devices are connected in a circle
  
  

• All devices are connected to a central hub or switch

• Devices are connected in a single line
  
  

• Devices are connected randomly

In a bus topology, how are devices connected?

• Through a central hub
  
  

• In a circular path

• Along a single communication line

• Wirelessly

What is a key disadvantage of a bus topology?

• Easy to add new devices

• Data travels in one direction only

• If the main cable fails, the entire network stops working
  
  

• It requires a central hub

Which topology is best described as devices connected in a closed loop

• Star topology

• Bus topology
  
  

• Ring topology

• Mesh topology

In a star topology, what happens if the central hub fails?

• Only one device stops working

• The entire network stops working
  
  

• The devices connect directly to each other

• The network speed increases

Which of the following is an advantage of a star topology?

• Easy to set up and expand
  
  

• More expensive to install

• Slower data transfer speed

• Difficult to troubleshoot

Which topology is the most cost-effective for small networks?

• Bus topology

• Star topology

• Ring topology
  
  

• Mesh topology

Which network topology ensures data travels in one direction only?

• Star

• Ring

• Bus

• Tree

Which device is commonly used in a star topology?

• Router

• Hub or Switch

• Repeater

• Bridge

What is a disadvantage of a ring topology?

• Data collisions occur frequently
  
  

• If one device fails, the entire network can be affected

• It requires a central hub
  
  

• It is difficult to expand
