Strictly speaking, using binary data to record movies, music, and pictures has caused serious damage and distortion to the original movie, music, and picture information, but humans are insensitive to this. "Guy", as long as these damages and distortions are controlled within the range that humans cannot detect, they can "muddle through" and make people happy! If you don’t believe me, you can use your computer to look at your digital photos. Don’t say too much, just zoom in 6 to 10 digits and see if you are still beautiful? Not at all, it’s just a very ugly mosaic! Using binary data to record movies, music, and pictures requires a process of sampling, quantification, and encoding. Just listen to the name and you will get a glimpse of it - "sampling" means taking a sample after a period of time (of course, how often should you take a sample? (It's sophisticated); then divide the sample into a limited number of small grids, which is called "quantification"; assign a suitable number to each small grid to represent it, and then the entire value of a sample will come out, which is called "quantification" coding". In this way, movies, music, and pictures are so-called "digitized." At this point, any base system can actually be used, but binary is the simplest.

More importantly, because binary is the easiest to record, store and exchange using circuits, current digital devices all use binary, so they are recorded in binary data...
