1. Given data:
File size = 1024 bytes
Payload size = 128 bytes.
TCP header is composed of 20 bytes
IPv4 header is composed of 20 bytes.
So total TCP/IP header is composed of 40 (20 + 20) bytes.
Distribute 1024 bytes into 8 segments, each segment has 128 bytes.
Then,
So total 1344 bytes will be sent including the entire TCP/IP overhead.
i)
Given data: IPv4 percentage overhead:
Total overhead in eight segments: 8*40= 320 bytes
Total data sent: 1024 bytes
Percentage overhead: (320/1024)*100= 31.25%
ii)
File size = 1024 bytes
File size = 1024 bytes

Payload size = 128 bytes.
TCP header is composed of 30 bytes
IPv4 header is composed of 30 bytes.
So total TCP/IP header is composed of 60 (30 + 30) bytes.
Distribute 1024 bytes into 8 segments, each segment has 128 bytes.
Then,
(60+128)*8= 1504 bytes
So total 1504 bytes will be sent including the entire TCP/IP overhead.
Protocol overhead:
IPv6 percentage overhead:
Total overhead in eight segments: 8*60= 480 bytes
Total data sent: 1024 bytes
Percentage overhead: (480/1024)*100= 46.87%
2. IP is a connection less protocol and however, TCP has been connection oriented. These two
protocols have been coexisting in the same protocol stack. There are four layers in TCP/IP
protocol that are stacked together in two different protocols for working in the close
organizations and execute network communication. The first layer is application layer of the
TCP/IP protocol and send HTTP request. The TCP layer used to get HTTP request from the
application layer and helps in breaking the overall message into several packets that are called as
data packets. These packets have been sent to internet layer in which these packets have been
