   <networking> (Or "host-host layer") The middle layer in the
   {OSI} seven layer model.  The transport layer determines how
   to use the {network layer} to provide a virtual error-free,
   point to point connection so that host A can send messages to
   host B and they will arrive un-corrupted and in the correct
   order.  It establishes and dissolves connections between
   hosts.  It is used by the {session layer}.

   An example transport layer {protocol} is {Transmission Control
   Protocol} (TCP).

   {OSI} documents: {ITU} Rec. X.214 (ISO 8072), ITU Rec. X.224
   (ISO 8073).
