Explanation / Answer
11) Once at recieve side network layer will recieve the packet based on ip it will understood that ok the packet i need to reciece and it will remove the ip address and sends to trnsport layer,so now transport layer will check for which porcess to give based on the port number why because in our system many porcess are running and finally it will send an acknoweldge to sender syaing that i recieved the packert why because at tcp we provides relaibility.
12 Data Link Layer
13) Application Layer
14) 1.It is a Connection oriented service because of that we can see the data transfer very relaibily
2.we can enssure that error-checked delivery.
15) Purpose of flow control is to manage the flow between 2 or more than 2 hosts.
Flow Control Techniques are Stop and Wait Protocol ,Go Back-N(GBN),Selectrive Repeat(SR)Protocol
16) ICMP Protocols like we want to check whether in a host all layers working or not in that case we use it.
17) Identify the host uniquely using ip address and incase of routing also ip address plays important role
18) Based on Ip adderess
19) TURE
20) 1.Increase the number of ip adderess in IPV6(128 Bit so 2 ^128 ip address are possible)
2.Header length was increased.
