Across
- 7. form of program documentation written into the program to be read by people and which do not affect how a program runs
- 10. 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.
- 12. 8 bits
- 13. data that are sent to a computer for processing by a program. Can come in a variety of forms, such as tactile interaction, audio, visuals, or text.
- 14. 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
- 15. 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.
- 18. A type of computer that forwards data across a network
- 19. the steps or phases used to create a piece of software. Typical phases include investigating, designing, prototyping, and testing.
- 21. the inputs and outputs that allow a user to interact with a piece of software. User interfaces can include a variety of forms such as buttons, menus, images, text, and graphics.
- 23. the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second
- 25. An agreed-upon set of rules that specify the behavior of some system
- 26. the series of connections between computing devices on a network starting with a sender and ending with a receiver
- 27. A way of representing information using only two options
- 29. A process for creating a digital representation of analog data by measuring the analog data at regular intervals called samples.
- 31. a system of linked pages, programs, and files
- 33. a collection of program statements. Programs run (or “execute”) one command at a time.
- 34. any data that are sent from a program to a device. Can come in a variety of forms, such as tactile interaction, audio, visuals, or text.
- 35. Error from attempting to represent a number that is too precise. The value is rounded.
- 37. Error from attempting to represent a number that is too large
- 38. differing access to computing devices and the Internet, based on socioeconomic, geographic, or demographic characteristics
- 40. a collaborative programming style in which two programmers switch between the roles of writing code and tracking or planning high level progress
- 41. a group of computing devices and programs working together for a common purpose
Down
- 1. a machine that can run a program, including computers, tablets, servers, routers, and smart sensors
- 2. A process for reducing the number of bits needed to represent something without losing any information. This process is reversible.
- 3. the protocol used for transmitting web pages over the Internet
- 4. Finding and fixing problems in an algorithm or program
- 5. the system responsible for translating domain names like example.com into IP addresses
- 6. A collection of public copyright licenses that enable the free distribution of an otherwise copyrighted work, used when an author wants to give people the right to share, use, and build upon a work that they have created
- 8. 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
- 9. a protocol for sending data across the Internet that assigns unique numbers to each connected device
- 11. a written description of how a command or piece of code works or was developed
- 16. program statements run in order, from top to bottom
- 17. a group of interconnected computing devices capable of sending or receiving data.
- 20. some program statements run when triggered by an event, like a mouse click or a key press
- 22. A work or invention that is the result of creativity, such as a piece of writing or a design, to which one has rights and for which one may apply for a patent, copyright, trademark, etc.
- 24. A way of representing information using ten options
- 28. 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.
- 30. a command or instruction. Sometimes also referred to as a code statement.
- 32. Data that changes discretely through a finite set of possible values
- 36. The unique number assigned to each device on the Internet
- 39. A contraction of "Binary Digit"; the single unit of information in a computer, typically represented as a 0 or 1
