Homonym: lossy (Compression)
"Lossy" refers to a type of data compression that reduces file size by permanently eliminating some information. This method is commonly used in formats like JPEG for images and MP3 for audio. While lossy compression can significantly decrease the amount of storage space needed, it can also lead to a reduction in quality, making it less suitable for applications where detail is crucial.
In contrast to lossless compression, which retains all original data, lossy compression prioritizes smaller file sizes over perfect fidelity. This trade-off is often acceptable for everyday use, such as streaming music or sharing photos online, where speed and convenience are more important than absolute quality.
