Detailed explanation-1: -Decapsulation is the process of removing the header and trailer information from a packet, as it moves toward its destination. The destination device receives the data in its original form.
Detailed explanation-2: -The network layer is responsible for the source-to-destination delivery of a packet, possibly across multiple networks (links). The data link layer is responsible for moving frames from one hop (node) to the next. The physical layer is responsible for movements of individual bits from one hop (node) to the next.
Detailed explanation-3: -When the packet arrives on the receiving host, the packet travels through the TCP/IP protocol stack in the reverse order from which it was sent. Figure 1–1 illustrates this path. Moreover, each protocol on the receiving host strips off header information that is attached to the packet by its peer on the sending host.
Detailed explanation-4: -When a packet arrives at the destination, how can the computer find which transport layer is involved? The protocol field (8-bits) of the datagram defines the transport-layer protocol that should receive the transport-layer packet. If the value is 06, the protocol is TCP; if the value is 17, the protocol is UDP.
