star and mesh topology

• What is topology in networking?

  A given arrangement of all network components
• What is the need for network topology?

  To define the arrangement of network devices
• What are the characteristics of bus topology?

  • Devices connected to a central backbone cable
  • If the backbone breaks, all devices lose connection
• What is a disadvantage of bus topology?

  If the backbone breaks, all lose connection
• What are the characteristics of ring topology?

  • Devices connected in a ring cable
  • If one connection breaks, all lose connection
  • A second ring can prevent this issue
• What is a disadvantage of ring topology?

  If one connection breaks, all lose connection
• How can a second ring help in ring topology?

  It can prevent all devices from losing connection
• What are the characteristics of star topology?

  • Every device connected to a central switch
  • If one connection breaks, others remain unaffected
  • More cabling needed, making it expensive
• What is an advantage of star topology?

  If one connection breaks, others remain connected
• What is a disadvantage of star topology?

  More cabling needed, making it expensive
• What is a partial mask network topology?

  • Many nodes exist but are not connected
  • Every device lowers the overall performance
  • Compared to a full network, it is less efficient
• What is needed for a LAN setup?

  Hard drive, computers, printers, switch, router, fiber optic cables, server
• List one hardware component needed for a LAN.

  Switch
• What is one function of a server in a LAN?

  To manage network resources
• What type of cable is mentioned for LAN setups?

  Fiber optic cables
