  1. 3. A system of linked pages, programs, and files
  2. 4. A group of interconnected computing devices capable of sending or receiving data
  3. 5. differing access to computing devices and the Internet based on socioeconomic, geographic, or demographic characteristics
  4. 9. 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. 10. a protocol for computers to request and share the pages that make up the world wide web on the Internet
  6. 14. the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second
  7. 18. A type of computer that forwards data across a network
  8. 19. A protocol for sending packets that does error-checking to ensure all packets are received and properly ordered
Down
  1. 1. can continue to function even in the event of individual component failures. This is important because elements of complex systems like a computer network fail at unexpected times, often in groups.
  2. 2. A protocol for sending packets quickly with minimal error-checking and no resending of dropped packets
  3. 6. The unique number assigned to each device on the Internet
  4. 7. 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
  5. 8. the series of connections between computing devices on a network starting with a sender and ending with a receiver
  6. 11. a machine that can run a program, including computers, tablets, servers, routers, and smart sensors
  7. 12. an agreed upon set of rules that specify the behavior of some system
  8. 13. data added to packets to help route through the network and reasemble the original message
  9. 15. the system responsible for translating domain names into IP addresses
  10. 16. a protocol for sending data across the Internet that assigns unique numbers (IP addresses) to each connected device
  11. 17. information passed through the internet in packets
  12. 20. the capacity for the system to change in size and scale to meet new demands
  13. 21. A group of computing devices and programs working together for a common purpose
