Question 1
Comparison of OSI reference model with TCP/IP networking model:
OSI Model: A reference model which used to know the process of communication over a
network is known as open systems interconnection (OSI) model. It is a conceptual framework
which understands the relationship. The purpose of this model is to create communication
between developers and vendors, using software programs and communication products. This
model is divided into seven layers. From layer one to four are considered as a lower layer and
five to seven areas an upper layer. OSI model is the group of seven different layers, these are the
presentation, network, physical, application, data link, transport and session (Rouse, 2014).
TCP/IP model: a conceptual model which has four layers and used to interconnect various
network devices on the internet. Transmission control protocol/Internet protocol is also a suite of
communication protocols. This model explains the process of applications that how application
use a network to create channels. TCP/IP is the combination of four layers, these are transport,
physical, application and network layer (study tonight, 2018).

OSI Model TCP/IP Model
1. This model is generic, used as a
communication gateway between the end
user and network.
Internet develop protocol and TCP/IP is
based on it. A protocol of communication
which host connection above a network.
2. Deliver the packets with the help of
transport layer.
Does not deliver any packets but more
reliable than OSI model.
3. It has a separate layer of session and
presentation and follows the vertical
approach
Does not have any separate layer and
follow horizontal approach.
4. OSI model’s transport layer is only
connection oriented.
The transport layer of TCP/IP layer is
both connectionless and oriented.
5. OSI model’s network layer is both
connectionless and oriented.
The network layer is only connectionless.
6. A reference model which used as a The way implementation of OSI model is

completed by TCP/IP model.
7. This model has an issue of fitting the
protocol in the model.
It does not have any protocol to fit.
8. OSI model has hidden protocol which can
be replaced at the time of change of
technology.
It is not possible to replace the protocol in
TCP/IP model.
9. OSI model has services, protocols, and
interfaces, which clearly define the model
and it’s also a protocol-independent
model.
The services, protocols, and interfaces are
not separated by this mode. And it is the
same as OSI model with protocol
dependent.
10. The OSI model is the combination of
seven different layers.
The TCP/IP model is the collection of
four layers.
(Studytonight, 2018)
After comparison and study of both models, I’ll prefer to work with TCP/IP model over OSI
model. The OSI model has a bad implementation with less timing and bad technology with bad
politics. The bad timing is related to the just finishing of this model after the research and the
waste of money. The bad technology relates to empty of two layers presentation and session
whereas data link is overfull. TCP/IP model has reliable implementation compare than OSI
model (learning network, 2014).
