 Open Systems Interconnection (OSI) reference
  model .It is develop by (1984) from (ISO) .
 A networking model introduced by the International
  Organization for Standardization (ISO) to promote
  multi-vendor interoperability. Open Systems
  Interconnection (OSI) is a seven-layered conceptual
  model consisting of the application, presentation,
  session, transport, network, data-link, and physical
  layers.
