- 2. A contraction of "Binary Digit"; the single unit of information in a computer, typically represented as a 0 or 1
- 5. A base-10 number system that uses ten distinct symbols 0-9 to represent numbers.
- 7. (2 words) Computer programs that are made freely available and may be redistributed and modified.
- 10. Data that changes discretely (individually separate or distinct) through a finite set of possible values.
- 12. The exclusive legal right given to a creator to print, publish, perform, film, or record literary, artistic, or musical material, and to authorize others to do the same.
- 15. Data that describes other data. For example, a digital image includes data that describes the size of the image, number of colors, or resolution.
- 16. (2 words) Online research output that is free of any and all restrictions on access and free of many restrictions on use, such as copyright or license restrictions.
- 17. A set of rules governing the exchange or transmission of data between devices.
- 18. Error from attempting to represent a number that is too precise. The value is rounded.
- 19. Short for "picture element" it is the fundamental unit of a digital image, typically a tiny square or dot which contains a single point of color of a larger image.
- 20. The standard fundamental unit (or "chunk size") underlying most computing systems today. One equals eight bits.
Down
- 1. A process for creating a digital representation of analog data by measuring the analog data at regular intervals called samples.
- 3. (2 words) 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, and/or trademark.
- 4. (2 words) 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.
- 6. A compression method in which some of the information is lost or thrown away. This process is not reversible.
- 8. A process for reducing the number of bits used to represent a piece of information.
- 9. Error from attempting to represent a number that is too large.
- 11. Data with values that change continuously, or smoothly, over time. Some examples of include music, colors of a painting, or position of a sprinter during a race.
- 13. A data compression algorithm that allows the original data to be perfectly reconstructed from the compressed data. Used for text compression and .gif images.
- 14. A way of representing information using only two options.
