In this lesson, you will learn about "the concept of compression," one of the most important topics in data representation. Rather than memorizing words alone, aim to explain the mechanisms and reasons in your own words.
Key Point
Lossless compression allows complete restoration, while lossy compression increases the compression ratio by reducing information that is difficult to perceive.
Lossless compression allows complete restoration, while lossy compression increases the compression ratio by reducing information that is difficult to perceive.
Important Point
- Check the reasons, not just the conclusion
- Distinguish similar terms and exceptions
- Try applying the same way of thinking to other examples
Practice
- Explain the key point in two sentences.
- Give one common misconception and explain how it differs.
- Check it by applying it to a familiar or concrete example.
