Before sending a packet into a datagram network, the source must determine all the links that packet will traverse between source and destination. False

False

Explanation:

The transport layer is found in both OSI and TCP/IP suite model. It segments and propagates packets across a network. TCP and UDP are protocols in this layer.

UDP is a connectionless protocol, that is to say, it needs no connection for transmission to take place. UDP transfer is unreliable as packets lost are not retransmitted. Unlike the TCP, it's header is smaller and it is faster in transmission, and links to destinations are random and not determined by the source.
