Answer to Question 1:
File size = 1024 bytes
Payload size = 128 bytes.
TCP header = 20 bytes
IPv4 header = 20 bytes.
So total TCP/IP header = 40 (20 + 20) bytes.
1024 bytes is divided into 8 segments, which means each segment has 128 bytes.
Then,
(40+128)*8= 1344 bytes
So total 1344 bytes will be sent and this include TCP/IP overhead.
i) Protocol Overhead
IPv4 percentage overhead:
Total overhead that is included in eight segments: 8*40= 320 bytes
Total data sent: 1024 bytes
Percentage overhead: (320/1024)*100= 31.25%
ii)
Divide 1024 bytes is divided into 8 segments and this specifies that each segment has 128 bytes.
Then,

(60+128)*8= 1504 bytes
So total 1504 bytes will be sent that includes the overall TCP/IP overhead as well.
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%
Answer to Question 2:
IP is termed as Internet Protocol and utilized as a numeric label for addressing the device
installed in a network. TCP is termed as transmission control protocol and utilized for
maintaining logical connection between the transport layer such that the message transmitted
over the network contains no errors and received as the same order that is sent from the ender
end (Kao, 2018). There are two different protocol of TCP and IP i.e. TCP (connection service)
and UDP (Connection Less service).
TCP protocol works in the transport layer and it monitors the congestion, order of packets
delivered and reliable link. It works for making sure that the data packets are transmitted
between two different sources and it has nothing to deal with the routes or the paths it is the work
of IP protocol (Nath & Uddin, 2015). The IP can use different paths or routes for forwarding the
data packets based on congestion or availability. The delivery of the data between the client and
