Answer #1

Q1. True

Because The transport layer protocol guarantees a reliable end-to-end connection between precisely two address spaces.

Q.2 true

Because The IP layer provides an unreliable, connectionless delivery system. The reason why it is unreliable stem from the fact the protocol does not provide any functionality for error recovering for datagrams that are either duplicated, lost or arrive to the remote host in another order than they are send.

Q3. True

The network layer routes a packet through a series of packet switches (i.e., routers) between the source and destination. To move a packet from one node (host or packet switch) to the next node in the route, the network layer must rely on the services of the link layer. It is often a mixed implementation of hardware and software.
