Across
- 2. The total number of pixels that make up a digital image, often written as width times height
- 6. The number of times per second that a sound wave\'s height is measured when converting it to digital data (2 words)
- 7. A type of file compression that shrinks a file without losing any of its original quality or data
- 10. A simple compression method that saves space by counting repeating sequences of data instead of saving each one individually (3 words)
- 11. A complete list of all the letters, numbers, and symbols that a computer can understand and display (2 words)
- 14. A basic unit of computer storage that is made up of a group of 8 bits
- 16. A classic 7-bit character set that can represent up to 128 different text characters
- 17. A modern, large character set designed to represent text and emojis from languages all around the world
- 18. Extra information saved inside an image file, such as its width, height, or colour depth, that helps the computer load it correctly
- 19. The base-2 number system made of 1s and 0s that computers use to process all data
Down
- 1. Moving all bits in a binary number to the left or right to multiply or divide it by two (2 words)
- 3. The number of bits used to represent the colour of a single pixel in an image (2 words)
- 4. An error that happens when a computer tries to save a binary number that is too large for its allocated storage space
- 5. A type of file compression that reduces file size by permanently deleting some of the original data
- 8. The number system that uses sixteen symbols, including letters A to F, as a shorthand for programmers
- 9. The tiniest dot of a single colour that makes up a digital image on a screen
- 12. The process of taking measurements of a sound wave at regular intervals to turn it into digital data
- 13. A compression method that saves space by giving shorter binary codes to characters that appear most often (2 words)
- 14. The smallest possible unit of information in a computer, which can only be a 0 or a 1
- 15. The number of bits used to store each sound sample, which affects the quality of the recorded audio (2 words)
