The technology that facilitates peer-to-peer file sharing without a central server is known as BitTorrent. This system allows users to distribute files across multiple computers, enabling efficient data transfer by splitting files into smaller pieces shared among several users simultaneously. It reduces the burden on a single server and improves download speeds, especially for large files. BitTorrent is widely used for sharing large media files, software distributions, and other content. Popular clients include qBittorrent and uTorrent.
