Kompresseeritakse

Kompresseeritakse is a term that generally refers to the act of compressing something. In a digital context, it means reducing the size of data, often by removing redundancy or using more efficient encoding methods. This process is crucial for efficient storage and transmission of information.

There are various types of compression algorithms. Lossless compression, as the name suggests, allows the original data to be perfectly reconstructed from the compressed version. Examples include ZIP and PNG formats, which are ideal for text, executable files, and images where exact fidelity is paramount.

Lossy compression, on the other hand, achieves higher compression ratios by discarding some of the original data that is deemed less perceptible to human senses. This is commonly used for media like JPEG images, MP3 audio, and MP4 video. While some quality is sacrificed, the resulting file size reduction is often substantial, making it practical for streaming and large media libraries.

The decision to use lossless or lossy compression depends heavily on the nature of the data and the intended application. For instance, compressing a document for backup would likely employ lossless methods, while compressing a movie for online viewing would typically use lossy compression. The underlying principle in both is to represent the information using fewer bits than the original representation.
