4. The number of bits used to represent the color of a single pixel in an image (2 words).
6. The smallest unit of data in a computer, which can be a 0 or a 1.
7. A small unit of computer storage made up of exactly four bits.
8. How many times per second a sound wave is measured when converting it into digital audio (2 words).
9. A group of eight bits that can represent a single character.
11. The process of reducing the file size of data so it takes up less storage space.
14. The total number of pixels that make up an image, often affecting how sharp it looks.
17. A collection of all the characters and symbols that a computer can recognize and display (2 words).
18. Extra information hidden inside a file that describes the data, like the date a photo was taken.
19. A type of file compression where some data is permanently removed to make the file much smaller.

1. The number of bits used to store each audio measurement in a sound file (2 words).
2. A type of file compression that reduces file size without losing any of the original data.
3. A basic compression method that simplifies data by counting how many times a value repeats in a row (3 words).
5. A method used to multiply or divide a binary number by moving its bits left or right (2 words).
10. The tiniest dot or square of color that makes up a digital image on a screen.
12. A number system that only uses two digits, zero and one.
13. A base-sixteen number system that uses digits zero to nine and letters A to F.
15. A modern character set designed to represent text and symbols from almost every language in the world.
16. Our everyday number system that uses ten digits, from zero to nine.
