Data Compression Formats - JSON

Data compression formats are technologies designed to reduce the size of digital data, improving storage efficiency and transfer speed. Formats such as ZIP, GZIP, RAR, and 7z employ different compression algorithms (Deflate, LZMA, BWT, etc.) to provide a balance of compression ratio and speed suited to various use cases. These formats are widely used for file archiving, web content transfer, backups, and software distribution.
