What is TORRENT?

A .torrent file doesn't contain the actual data you want to download - it contains information about that data. It includes tracker URLs (servers that coordinate peers), file names, sizes, folder structure, and cryptographic hashes to verify data integrity. When you open a .torrent file in a BitTorrent client, it connects to peers who have pieces of the actual files and downloads them in a distributed manner.

BitTorrent is a decentralized protocol used for distributing large files like Linux distributions, open-source software, game updates, and public domain media. Torrent files are typically tiny (under 100 KB) even for gigabytes of content. The technology enables efficient downloads by getting pieces from multiple sources simultaneously.

Did you know? BitTorrent handles over 3% of all internet traffic worldwide!

History

BitTorrent was created by Bram Cohen to solve the problem of distributing large files to many people efficiently without requiring massive server bandwidth.
