Across
  1. 2. the inclusion of extra components so that a system can continue to work even if individual components fail, for example by having more that one path between any two connected devices in a network
  2. 3. A chunk of data sent over a network. Larger messages are divided into packets that may arrive at the destination in order, out-of-order, or not at all.
  3. 4. Information passed through the internet in packets.
  4. 5. a group of interconnected computing devices capable of sending or receiving data.
  5. 7. A protocol for sending packets that does error-checking to ensure all packets are received and properly ordered
  6. 10. the series of connections between computing devices of a network starting with a sender and ending with a receiver.
  7. 14. A protocol for sending packets quickly with minimal error-checking and no resending of dropped packets
  8. 15. The unique number assigned to each device on the internet.
Down
  1. 1. a machine that can run a program, including computers, tablets, servers, routers, and smart sensors.
  2. 3. An agreed-upon set of rules that specify the behavior of some system
  3. 6. a protocol for sending data across the internet that assigns unique numbers (IP Addresses) to each connected device.
  4. 8. Data added to packets to help route them through the network and reassemble the original message.
  5. 9. A type of computer that forwards data across a network
  6. 11. the maximum amount of data that can be sent in fixed amount of time usually measured in bits per second.
  7. 12. a group of computing devices and programs working together for a common purpose.
  8. 13. Can continue to function even in the event of individual component failures. This is important because element like complex systems like a computer network fail at unexpected time often in groups.
