Data Compression Intuition
Data compression means finding a shorter way to store or send information, sometimes representing it exactly and sometimes approximating it closely enough that the difference is barely noticeable, so it takes up less storage space or travels faster over a network. For example, instead of storing "10 red, 10 red, 10 red" three separate times, a compressed version might just store "red, repeated 30 times," since it means exactly the same thing using fewer symbols.
