A torrent is a file-sharing method that uses peer-to-peer (P2P) technology, allowing users to download and upload files directly from and to each other instead of relying on a central server. Torrent files contain metadata about the files to be shared and are opened with special software called torrent clients. While torrents are widely used for distributing large files efficiently, they are also commonly associated with the sharing of copyrighted or pirated content, raising legal and security concerns.
