Across
  1. 2. a protocol for sending packets that does error-checking to ensure all packets are received and properly ordered
  2. 6. a protocol for sending packets quickly with minimal error-checking and no resending of dropped packets
  3. 8. information passed through the internet in packets
  4. 11. the inclusion of extra components so that a system can continue to work even if individual components fail, for example by having more than one path between any two connected devices in a network
  5. 13. continuing to function even in the event of individual component failures
  6. 16. a protocol for sending data across the Internet that assigns unique numbers (IP addresses) to each connected device
  7. 19. a group of interconnected computing devices capable of sending or receiving data
  8. 21. data added to packets to help route them through the network and reassemble the original message
Down
  1. 1. a chunk of data sent over a network
  2. 3. a machine that can run a program, including computers, tablets, servers, routers, and smart sensors
  3. 4. the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second
  4. 5. an agreed-upon set of rules that specify the behavior of some system
  5. 7. a network used in data centers where data must be exchanged with very little delay
  6. 9. a type of computer that forwards data across a network
  7. 10. the number of bits of data that are sent each second; measures the speed of network connections
  8. 12. measures how late the bits arrive
  9. 14. the most common type of network; covers a limited area like a house or school
  10. 15. the series of connections between computing devices on a network starting with a sender and ending with a receiver
  11. 17. the largest type of network; extends over a large geographic area and is composed of many LANs
  12. 18. a group of computing devices and programs working together for a common purpose
  13. 20. the unique number assigned to each device on the Internet
