In this lesson, you will learn about “files and compression,” one of the most important concepts in how computers work. Rather than memorizing words alone, aim to explain the system and the reasons behind it in your own words.
Key Point
Compression reduces the amount of data by using patterns in the data, and lossless compression can restore the original data completely.
