If you use a conventional tool, even wget, you are making one connection to a remote server. If that server goes down, or slows down, your transfer slows down too. Regardless of the bandwidth you have available, you are limited by the bandwidth of the remote server (or of the slowest link between you). Again, if the transfer is interrupted, you lose. You must start again. More than once, I've lost a complete Red Hat download because, after downloading 80% of (say) a CD image, the connection failed somewhere and all was lost. BitTorrent establishes multiple connections between your computer and others which have the files you want. The files are transferred in multiple pieces. If a single connection fails, you only lose a portion of the data you are transferring; the previously downloaded parts are still valid. Since you have multiple connections, you are less likely to overwhelm any one of them, and more likely to use all of the bandwidth you have to receive data. BitTorrent manages the incoming pieces and makes sure they are intact and correct. In payment for a more-efficient download, your system also turns into a server for the length of time you are running BitTorrent. So others are downloading from you at the same time you are downloading from others. Erik
