Denis Baya CH.5 Questions: 1,2,3,4,5 and 6 1. What are the four basic processes used in the network layer to accomplish end-to-end transport? A: - Addressing packets with an IP address- The IP requires each sending and receiving device to have a unique IP address. The IP address of the sending host is known as the source IP address and the IP address of the receiving host is referred to as the destination IP address. -With Encapsulation, each PDU sent between networks needs to be identified with source and destination IP addresses in an IP header. The IP header contains the address information and some other bits that identify the PDU as a network layer PDU. That process is called encapsulation. -Routing is what connects the networks.

At the network layer, the router opens the packet and looks in the packet header for IP address
