File-sharing program Guide, Meaning , Facts, Information and Description

peer-to-peer.

File-sharing programs are used to directly or indirectly transfer filess from one computer to another over the Internet, over a smaller Intranet, or across simple networks usually following the peer-to-peer (P2P) model.

A variety of file-sharing programss is available on several different networks. Availability depends partly on operating system, and different networks have different features (for example, multiple-source downloads, different sorts of search limiting, and so on). It is common for commercial file sharing clients to contain abrasive advertising software, or spyware.

Categories of clients:

• Centralized Clients: OpenNap
  • Benefits: Faster searching and downloading
  • Negatives: Often more vulnerable to legal and DDOS attacks

• Decentralized clients: Gnutella
  • Benefits: Usually more reliable and rarely shut down
  • Negatives: Generally slower than centralized systems

• Decentralized tracker-based clients: Bittorrent
  • Benefits: Very fast due to concentration of bittorrent networks on a single file, is principally used to offer new, large files for download
  • Negatives: Not centrally searchable, tracker sites are often closed down or fail, not truly anonymous

• Multi-network clients
  • Benefits: allows connection to more than one network, almost always on the client side.
  • Negatives: often playing catch-up to individual networks' changes and updates.

• Anonymous peer-to-peer: Freenet, GNUnet, MUTE, I2P
  • Benefits: allows for the uncensored free flow of information and ideas
  • Negatives: due to anonymity it allows for questionable or illegal material to be exchanged easier than other networks, often slower then regular p2p because of the overhead
