Before sending a packet, IPv4 establishes contact with the destination by using the Address Resolution Protocol (ARP) to map the destination IP address to a MAC (Media Access Control) address on the local network. If the destination is on a different network, IPv4 sends the packet to the default gateway, which is determined by the subnet mask. The packet includes the destination IP address, and the network layer handles routing it through the appropriate paths until it reaches the destination.

What is packet marking?
If we are sending a file in one go and if some error occurred in between the file transfer then the complete file has to be resend which wastes the bandwidth so to prevent this, the file to send is divided in to smaller unit which we call packet, and then send packets 1 by one so that if a packet is lost then we need to send only that particular packet not the complete file. As the packet reaches its destination, the destination source send acknowledgement to the sender that the packet has reached to it and it may send the next packet and if packet somehow lost before reaching to the destination source, then the sender itself resends the packet after a fixed amount of time.

What is delivery report of IP?
The delivery of Packet byDestination Computerin TCP\IP stack is reported by sending Acknowledgement to the Source Computerfor the received Packet by Destination Computer.
In a connectionless system which of the following is correct?
The destination is not contacted before a packet is sent.
How does UDP differ from TCP?
TCP is connection oriented protocol,mean it ensure that a packet is delivered and also set up a connection before sending data to destination source and destination exchange several control signal before sending data.If a packet is lost,TCP resend it. UDP does not establish any communication before sending data.It sends data and forget it.If a packet is lost,application using UDP cannot resend it.A example of UDP is voip,if a packet is lost,a part of conversation is also lost and can not be resend
What does unicast transmission mean?
Unicast transmission is a commonly used term in the technology world. Unicast transmission is essentially the sending of messages to a single network destination, which is identified by an address.
What is packet ratio?
the ratio of the number of delivered data packet to the destination. This illustrates the level of delivered data to the destination.∑ Number of packet receive / ∑ Number of packet send
What correctly describes the addressing that Host A will generate in the process of attempting to contact Server B?
A frame with the destination MAC address of Router_A A packet with the destination IP of Server_B.
What part of a packet is used to get to destination?
Destination address
What is the function of transport layers?
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.
Which portion of the packet does a router use to forward the packet to the destination?
The Destination Address (Layer 2 or Layer 3)
Which layer of the osi model always provides the address of a packet's final destination?
Network - Always identifies the final destination of a packet
