Across
- 2. 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.
- 3. Data added to packets to help route them through the network and reassemble the original message.
- 6. 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.
- 7. a protocol for sending data across the Internet that assigns unique numbers (IP addresses) to each connected device
- 10. A type of computer that forwards data across a network
- 13. A way of representing information using only two options.
- 14. a machine that can run a program, including computers, tablets, servers, routers, and smart sensors
- 15. A contraction of "Binary Digit"; the single unit of information in a computer, typically represented as a 0 or 1
- 16. A process for creating a digital representation of analog data by measuring the analog data at regular intervals called samples.
- 19. An agreed-upon set of rules that specify the behavior of some system
- 21. differing access to computing devices and the Internet, based on socioeconomic, geographic, or demographic characteristics
- 23. the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second.
- 24. a group of interconnected computing devices capable of sending or receiving data.
- 25. Error from attempting to represent a number that is too large.
- 27. A process for reducing the number of bits needed to represent something in which some information is lost or thrown away. This process is not reversible.
Down
- 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.
- 4. Data with values that change continuously, or smoothly, over time. Some examples of analog data include music, colors of a painting, or position of a sprinter during a race.
- 5. the series of connections between computing devices on a network starting with a sender and ending with a receiver.
- 8. a system of linked pages, programs, and files.
- 9. A process for reducing the number of bits needed to represent a piece of information
- 11. Error from attempting to represent a number that is too precise. The value is rounded.
- 12. Data that changes discretely through a finite set of possible values
- 17. The unique number assigned to each device on the Internet.
- 18. the process of finding a path from sender to receiver.
- 20. A type of computer that forwards data across a network
- 22. A process for reducing the number of bits needed to represent something without losing any information. This process is reversible.
- 26. 8 bits
