Komprimierungs

Komprimierungs, also known as compression, is a process used to reduce the size of data. This reduction is achieved by encoding information using fewer bits than the original representation. Compression techniques can be broadly categorized into lossless and lossy compression.

Lossless compression algorithms allow the original data to be perfectly reconstructed from the compressed data. This is crucial for data where even a small loss of information would be detrimental, such as text files, executable programs, or medical images. Examples of lossless compression include ZIP, GZIP, and PNG. These methods work by identifying and eliminating statistical redundancy in the data.

Lossy compression, on the other hand, achieves higher compression ratios by discarding some of the original data. This is acceptable for data where perfect fidelity is not required, such as audio, video, and photographic images. The discarded information is typically imperceptible to humans. Examples of lossy compression include JPEG for images, MP3 for audio, and MPEG for video. These algorithms exploit the limitations of human perception to remove less important details.

The choice between lossless and lossy compression depends on the specific application and the tolerance for data loss. Compression is widely used for efficient storage and faster transmission of data across networks.
