      1. The kind of communication found in a system
     using layered protocols.  Each software or hardware
     component can be considered to communicate only with its
     peer in the same layer via the connection provided by the
     lower layers.

     2. A decentralised file sharing system like BitTorrent,
     Gnutella or Kazaa where computers that download data also
     store that data and serve it to other downloaders.  This
     increases the total bandwidth available in proportion to the
     number of users and so reduces download time.  It also
     improves resilience by providing multiple redundant sources
     for the same data.  This contrasts with client-server where
     all clients download the data from a single server (or
     mirror), sharing its fixed bandwidth.
  
     Peer-to-peer networks are typically ad-hoc and rely on users
     sharing the content they have downloaded for the benefit of
     other users.  Users who fail to do this are called "leaches".
     A "seed" is a node on a peer-to-peer network that is
     sharing a complete copy of a file, as opposed to other nodes
     that may only have some of the parts into which the file has
     been split.
