What are the different compression techniques and how do they compare?
There are two main types of compression techniques: lossless and lossy. Lossless compression retains all original data, while lossy compression reduces file size by removing some data. Examples include ZIP for lossless and JPEG for lossy.
Can you give me examples of each type?
Sure! For lossless compression, examples include PNG for images and FLAC for audio. For lossy compression, JPEG for images and MP3 for audio are common.
What are the advantages of using lossless compression?
Lossless compression is ideal when you need to preserve the original quality of the data, such as in text files or high-quality images. It allows for exact reconstruction of the original data.
Are there any disadvantages to using lossy compression?
Yes, the main disadvantage is that some data is permanently lost, which can affect quality. This is particularly noticeable in audio and video files when compressed too much.
