Networks

• Network Topology


  A type of networking infrastructure design such as bus, star, or ring
• Packet Loss

  When data packets are lost or corrupted, causing them to have to be resent
• Latency

  The delay between sending and receiving data, impacting the performance of the network
• Network Traffic

  The amount and type of data being transmitted
• What does LAN stand for?

  Local Area Network
• what does WAN stand for?

  Wide Area Network
• what is a Full Mesh Network?

  All devices are connected to every other device, withy no central device. Packets can be sent down different routes in the event of a bottleneck or if a connection goes down
• What is a partial mesh network?

  Most devices are connected to each other, there is no central device.
• What is a Star network topology?

  All devices must connect to a central device, every packet must pass through central device. not all devices have the same permissions
• What are the advantages of a star netowork topology?


  • Less cabling required
  • Easier to add/remove devices
  • simple to understand and troubleshoot
• What are the disadvantages of a star network topology?


  • if central device fails then the whole network fails
  • can cause a bottleneck in a busy server
• What are the advantages of a Full mesh network?


  • if one connection fails then the network still works
  • faults can be identified easily
• what are the disadvantages of a full mesh network?

  • succeptable to data breaches
  • More cabling required
• What are the advantages of a partial mesh network?

  • more reliable are one failed connection wont stop the server
  • allows packets to be rerouted around a bottleneck
• What are the disadvantages of a partial mesh network?


  • needs more cabling
  • more complicated to add/remove devices
