Clues

  • data packets move back up the layers in the opposite way these layers are good as they are self contained (9, 7)
  • It is how devices format data ready to send(when nodes need to send information they will wait for the connection to be "quiet" before transmitting.Two nodes attempting to transmit simultaneously will stop and wait random periods before reattempting (8, 9)
  • Measured in Mbps (Megabits per Second) (10, 6)
  • Resources such as printers are shared saving money, You can access your files from any computer in the network, Data is easy to back up as it is stored centrally on the server (20)
  • routers direct packets across other nodes/routers to get to the receiver the quickest using the least busy route (3, 3, 7, 4)
  • selects the correct protocol to use depending on what you are doing(banking would be https for security) (11, 5)
  • some terminals in the connected to each other(there is not a link form each one to every other terminal)Also no central server Often used in conjunction with star topology s to create larger networks (7, 4, 7)
  • the formula for encrypting the plaintext (10, 9)
  • The IP (Internet Protocol) address it is going to The IP address it has come from The sequence number of the packet The number of packets in the whole communication Error checking data (7, 8)
  • used for BBC iplayer and can be easily used for illegal distribution of copyright material such as films and music (4, 2, 4, 2, 1, 3)
