Veszteségtl

Veszteségtl is a Hungarian word that translates to "lossless" in English. It describes a process, compression method, or data format where no information is discarded. In the context of data compression, lossless algorithms allow the original data to be perfectly reconstructed from the compressed version. This is in contrast to lossy compression, where some data is intentionally removed to achieve smaller file sizes, resulting in a loss of fidelity.

Lossless compression is essential for applications where data integrity is paramount. Examples include text files, executable programs, scientific data, and certain types of images like those used in medical imaging or archival purposes. Common lossless compression algorithms include ZIP, GZIP, PNG, and FLAC. When you zip a document or download a software update, you are typically using lossless compression to ensure that every bit of the original data is preserved. The trade-off for perfect reconstruction is that lossless compression generally achieves lower compression ratios compared to lossy methods.
