Answer 1

At the Transport Layer (equivalent to Layer 4 in the OSI model), two protocols exist:

TCP (Transmission Control Protocol) - breaks information into datagrams and sends them, carrying out resends, if required, and reassembles received datagrams, it gives 'reliable' delivery, a connection-oriented service between applications.

UDP (User Datagram Protocol) - does the same as TCP but it does not carry out any checking or resending of datagrams, so it is described as 'unreliable', a connectionless service (See UDP).

IP Datagrams are 'connectionless', however the TCP segment is 'connection-oriented'.
