Across
- 3. error that is produced when a computer is used to perform real number calculations because many real numbers can not be represented exactly on a computer.
- 4. a programs that are made freely available and may be redistributed and modified
- 7. a mistake in the algorithm or program that causes it to behave incorrectly or unexpectedly.
- 8. (short for binary digit) is the smallest unit of data in a computer. A bit has a single binary value, either 0 or 1
- 9. a sequence of instructions or steps, written in a language that can be understood by a computer, that will be used by the computer to complete a task or solve a problem.
- 13. Compression a data compression algorithm that allows the original data to be perfectly reconstructed from the compressed data.
- 16. is a system for representing the colors to be used on a computer display. Red, green, and blue can be combined in various proportions to obtain any color in the visible spectrum.
- 17. a problem-solving approach (algorithm) to find a satisfactory solution where finding an optimal or exact solution is impractical or impossible.
- 19. The background of a project performs functions through scripting.
- 23. a online research output free of any and all restrictions on access and free of many restrictions on use, such as copyright or license restrictions
- 24. Compression a data encoding and compression technique that deliberately discards some data in the compression process.
Down
- 1. a programmer hides all but the relevant data about an object in order to reduce complexity and increase efficiency
- 2. occurs in a computer or similar device when a mathematical operation results in a number that is smaller than what the device is capable of storing.
- 5. hand simulating the execution of program code in order to manually verify that it works correctly.
- 6. Different types of blocks are linked together.
- 8. Puzzle-piece shapes that are used to create code in Snap!.
- 10. a complete, well-defined sequence of steps for completing a task or solving a problem.
- 11. a numbering scheme in which there are only two possible values for each digit:0 and 1.
- 12. a unit of data that is eight binary digits long. Bytes are often used to represent a character such as a letter, number, or space.
- 14. An object in Snap! which performs functions controlled by scripts.
- 15. the process of identifying and removing errors from computer hardware or software.
- 18. a public copyright license that enables the free distribution of an otherwise copyrighted work. This is used when the content creator wants to give others to right to share, use and build upon the work they have created.
- 20. a minute area of illumination on a display screen, one of many from which an image is composed.
- 21. American Standard Code for Information Interchange, a character encoding standard for electronic communication
- 22. an error that occurs when calculated data cannot fit within the designated field.
