network topologies

• What is the main feature of a star topology?

  All devices are connected to a central device
• How does a star topology manage device connections?

  Through a central switch or server
• What happens if a device fails in a star topology?

  The rest of the network remains unaffected
• What is a benefit of adding devices to a star network?

  It's simple to add more devices
• How does data transmission in a star topology compare to a ring network?

  Data goes straight to the central device
• What is a drawback of a star topology regarding the central device?

  If the central device fails, the network fails
• What is a characteristic of a bus topology?

  Devices are arranged in a line
• How does data transmission occur in a bus topology?

  Data is sent in both directions
• What is a disadvantage of a bus topology?

  Data collisions slow the network
• What is a key feature of a ring topology?

  Data moves in one direction around the ring
• What is a limitation of data transmission in a ring topology?

  Only one device can send data at a time
• How does a mesh topology differ from a star topology?

  Devices are connected to each other directly
• What is the main advantage of a mesh topology?

  There is no single point of failure
• How do mesh networks send data?

  Along the fastest route between devices
• What is a full mesh topology?

  Every device is connected to every other device
• What has made mesh networks more practical recently?

  The use of wireless technology
• What is a partial mesh topology?

  Not all devices are fully connected
• What are the pros and cons of a star topology?

  Pros:

  • Network unaffected by single device failure
  • Simple to add devices
  • Better performance with fewer data collisions

  
  

  Cons:

  • Central device failure affects the whole network
  • Wired networks can be expensive
• What are the pros and cons of a mesh topology?

  Pros:

  • No single point of failure
  • Data sent along the fastest route

  
  

  Cons:

  • Traditionally expensive due to wiring
  • Complexity in setup
• How do the layouts of different network topologies compare?

  • Star: Central device connects all
  • Bus: Devices in a line connected to a backbone
  • Ring: Devices in a circle
  • Mesh: Devices interconnected without a central device
