Detailed explanation-1: -In lossy compression, the data in a file is removed and not restored to its original form after decompression. Specifically, data is permanently removed, which is why this method is also known as irreversible compression.

Detailed explanation-2: -Lossy compression sacrifices data to reduce file size, resulting in lower-quality files. Lossless compression preserves data integrity for higher-quality files and is often used for text-based files, where data integrity is critical.

Detailed explanation-3: -Lossy compression is most commonly used to compress multimedia data (audio, video, and images), especially in applications such as streaming media and internet telephony. By contrast, lossless compression is typically required for text and data files, such as bank records and text articles.
