|(networking)||transport layer - (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).
