Q. 1
OSI Model- Open system interconnection is the protocol with the help of them makes digital
communication in the network system. OSI model provides a guide structure evaluation of
the product and services.
Main layers of the OSI Model
(1) Application Layer: Application layer is the communication protocol in which determines
the network capacity. The application layer is the service in which information data and
application is presented in the visual form.
(2) Presentation Layer: Presentation layer is the protocol in which operating system analysis
the input and output data structure of the network protocol.
(3) Session Layer: In the session layer coordinate with the internet protocol and data
protocol to justifying the reconnection in the communication level.
(4) Network Layer: Network layer handle all the sending data from the outgoing
transmission system (Aldosari et al., 2015).
(5) Data link Layer: Data link provides a structure in which all the information is sent in the
form of data packets.
(6) Physical Layer: It is the combination of the electrical and mechanical radio waves. With
the use of them transmit the information through the network in the form of the bit.
TCP/IP protocol: Transmission control protocol and internet protocol is the communication
platform in which all the network device is inter-connect to each other through the internet
protocol.

Q. 2
OSI layers are managing the communication level through the TCP/IP internet protocol. For
managing the network connection in the operating system analysed the OSI mechanism.
The basic requirement of the OSI layers for the protocol suite
(1) OSI Application Layer: With the help of the application layer analysis the conversation
of the user data protocol. TCP justifies communication services through the internet network.
(2) OSI Datalink Layer: With the help of the data link layer follow the information frame in
the form of data packets. IP obtains wireless communication with the help of internet
application (Browne et al., 2018).
(3) OSI Physical Layer: In this layered protocol according to the network protocol
communicate the information through the TCP mechanism. With the help of the IP
application analysis, the communication system in the network functions.

Q. 3
Network Support Layer: For the network communication analysis the basic requirement of
the internet protocol application. In the network support with the help of the transport layer
and application layer analysis the communication framework according to the condition of
the operating system. The control protocol follows the network access according to the
capability of the internet.
User Support Layer: For manage, internet access uses the presentation and session layer for
the network application. In the user, support identifies the basic requirement of the operating
system according to the internet application. With the help of the presentation, layer manages
the output source of the information data. Session layer identifies the network connection and
user authentication according to the access of the internet (Chavan et al., 2016).

Q. 4
Data Encapsulation: Data encapsulation is the application protocol in which implements the
data details which is hidden from the user side. It is the method with the help of them user
hidden the information from the operating system protocol. In this application according to
the user operation member hide the information details for the internet protocol. It is the type
of data hiding from the user side. The aim of this function is to increase the data structure rate
according to the user requirement (Dike et al., 2016).
Data encapsulation is the method in which according to the data array hide the interface
information from the user side. The basic concept of this application is protecting private data
from the public class. With the use of the public and private security key function analysis the
user information according to the internet application.

Q. 5
Responsibilities of the Data Link Layer- DL layer play a vital role to communicate the
network selection according to internet access. With the help of this layer transmit the
information in the form of bits and packets. In the computing network to manage the
communication channel transport the network protocol. With the use of DL layer application
control the logical function, identify the media access and address the hardware position
according to the network selection.
DL layer provides a path function in which all the network protocol is access according to the
transmit data. All the communication session of the network mechanism is identified
according to the media control application. Link layer provides a network structure in which
implement the data according to the user requirement. This application provides network
access in which according to the communication channel defines the user information
(Marshall et al., 2016).

Q. 6
Network Layer Delivery: With the help of the network layer delivery information should be
transferred in the form of packets from the main source to final destination across multiple
user networks. This layer provides the information connection service between the different
panel networks. The main function of this layer manages the sequence of the information
packets and reduces the error control. In this network, the protocol addresses the different
type of network destination according to the layer protocol (Martin-Martínez et al., 2016).
Transport Layer Delivery: In this delivery mechanism complete message is transferred
from one network to another network. It is the network protocol in which identifies the
connection-oriented according to the network selection. In this network structure
information, the message is divided into the packet form in the source and in the end position
at destination entire message is reassemble according to the network protocol.

Q. 7
The mechanism for the Transport Layer: In the transport layer according to the network
service determines the communication level of the network protocol. The reliability of the
network selection in the transport layer is defined according to the network connection. With
the help of this layer make the communication protocol in the network application. The
transport layer is the network segment in which find out the process delivery according to the
communication plan.
All the connection protocol is managed by this layer mechanism. The main aim of this layer
mechanism is to provide the proper connection between all the network protocols. According
to the network connection communication protocol is the path function which is based on the
internet control protocol mechanism (Noh et al., 2015).

Q. 8
Network Layer Responsibilities: Network layer is the application protocol in which analysis
the transmission rate of the information data. In this network selection according to the
information wavelength determine the source and destination of the information protocol.
The main function of this layer is transmitting the information from the source in the form of
the wave to the destination of the network source. In this application, according to the
network, an IP connection assists the network system.
With the help of the network protocol information should be transmitted from one to another
resource with the help of internet access. According to the internet, layer defines the
information source and destination and then transmits the information from one to another
source. The main aim of this layer is to identify the transmit source according to the network
position and communication protocol (Peng et al., 2019).
