Data Representation

2. the number of bits used to record each sound sample (6, 10)
5. a base 16 number system that uses the value 0-9 and characters A-F
7. it contains all the characters that are in that character set and the binary value that is assigned to each character(9,3)
8. a unique address that is given to a computer at the manufacturing stage that can be used to identify the computer(3,7)
9. the number of bits that are used to create each colour in an image (6,5)
15. a continuous stream of data that is processed by humans(8,4)
17. a method that uses an algorithm to reduce the size of a file
18. a very small dot of colour that is displayed with many others to create an image
19. a small component in a computer system that is used to temporary store data
21. a very small component in a computer system that controls the flow of electricity(5,4)
22. additional data that is stored with an image that can provide information such as the dimensions of the image and the time and date the image was taken

1. a type of error that often occurs when a number larger than a register can store is generated.(8,5)
3. a compression method that reduce the size of a file by temporarily altering data
4. discrete data that only uses the values 0 and 1(7,4)
6. the number of samples recorded each second (5,4)
10. an algorithm that groups together repeating patterns and indexes them (3,5,8)
11. a base 2 number system that uses the values 0 and 1
12. a little piece of sound that is recorded at regular time intervals (5,8)
13. a process that is used in lossy compression that removes sounds that are not normally heard by the human ear (10,5,7)
14. a compression method that reduces the size of a file by permanently removing data
16. the dimensions of an image
20. a base 10 number system that uses the values 0 to 9
