Q

What are the functions of the

TCP/IP transport layer

(host-to-host layer)

A
  • establishes connections between applications that the source & destination hosts are communicating with
  • breaks application layer information into segements

2 methods of delivery:

  • connection oriented - TCP
  • connectionless - UDP
