Answer / guest
Answer: D
The Transport layer does the following: Responsible for
end-to-end
integrity of data transmission. Handles multiplexing upper-layer
application, session establishment and tear down of virtual
circuits.
Hides details of network dependent info from the higher
layers by
providing transparent data transfer. The 'windows' works at
this level
to control how much information is transferred before an
acknowledgement
is required.
