Tunneling, but you should really read your textbook before asking routing questions online... ;)
During the encapsulation process, the destination and source IP addresses are added to the packet header. These addresses help routers and networking devices determine where to route the packet to reach its destination.
Data, Segment, packet, frame, bit in that order
Frame, packet, segment, and lastly data shows the correct order of PDU de-encapsulation when a device receives messages from a network.
a packet is another word for folder
# a packet is another name for ceal or plastic wrapping holding a substance
Packet
It's called DNA.
The packet of electromagnetic radiation is the photon.
It ensures that the Packet gets to its destination or it ensures packet delievry . If a packet fails to get its destination, it handles the process of notifying the sender.
The router encapsulates the packet in the appropriate data link frame type for the outgoing data link. The router determines the exit interface after data encapsulation.
its a long process
At the OSI Layer 3, which is the Network layer, encapsulation involves adding a header to the data packet that includes crucial information for routing. This header contains the source and destination IP addresses, which facilitate the proper delivery of packets across different networks. Additionally, it may include other information such as the Time to Live (TTL) and protocol type, aiding in the management of the packet's journey through the network.
