Unit 1

2. error Error from attempting to represent a number that is too precise; the value gets rounded
5. Creating a digital representation of analog data by measuring it at regular intervals
8. error Error from attempting to represent a number that is too large for the available bits
9. Single unit of information in a computer; can be 0 or 1
10. data Data with values that change continuously (smoothly) over time
11. Unit of digital information that most commonly consists of eight bits
13. compression Reducing bits needed by throwing away some information; not reversible

1. compression Reducing bits needed without losing any information; reversible
3. Making a digital file smaller by using fewer bits to represent the same content
4. One small square in a digital image that stores a single color value
6. Legal protection that gives creators rights over copying and sharing their work
7. data Data that changes discretely through a finite set of possible values using 1s and 0s
10. simplification of something more complex
12. number Base 2 number system that uses only 0 and 1
