The document summarizes the OSI model and TCP/IP protocol suite. It describes the 7 layers of the OSI model and the functions of each layer. It also discusses the TCP/IP protocol suite and how it maps to the OSI model, having 5 layers - physical, data link, network, transport, and application. It compares the OSI and TCP/IP models, noting they have a similar functionality but the TCP/IP model was devised based on existing protocols rather than defining protocols based on the model.

TCP/IP and OSI Modal
OSI Reference Model:-
The seven layers of the OSI model are as follows:
· Physical layer: Converts the data into the stream of electric or analog pulses that will actually cross the transmission medium and oversees the transmission of the data
· Data Link layer: Provides an interface with the network adapter; maintains logical links for the subnet
· Network layer: Supports logical addressing and routing
· Transport layer: Provides error control and flow control for the internetwork
· Session layer: Establishes sessions between communicating applications on the communicating computers
· Presentation layer: Translates data to a standard format; manages encryption and data compression
· Application layer: Provides a network interface for applications; supports network applications for file transfer, communications, and so forth
TCP/IP Protocol Architecture
TCP/IP protocols map to a four-layer conceptual model. The four layers of model are: Application, Transport, Internet, and Network Interface. Each layer in model corresponds to one or more layers of the seven-layer Open Systems Interconnection (OSI) model.
The APRANET initially started with four Internet message processors (IMPs), located at the UCLA, UCSA, Stanford research institute and the University of Utah. In the early years, the purpose and usage of the APRANET network was widely discussed, leading to many enhancements and modifications as the users steady increased and requested demanded more from the network. As time passed many enhancements were made to the existing protocol but by 1973 it was clear that NCP (Network Control Protocol) was unable to handle the volume of traffic passing through it network and proposed a new functionality. A new protocol TCP/IP Transmission Control Protocol / Internet Protocol was developed over time to replace NCP.

Solution
1) a) At what level of OSI the routers operates : The routers operates at the third layer of the
model which is Network Control Layer, where a router examines the packets\' data structure and
determine whether to forward or not.
b) At which level of the OSI model, bits are packaged into frames : Bits are packaged into
frames at data link layer, which setups the links accross the physicsl network.
c) Layers of OSI model : The seven layers of OSI are Physical Layer, Data Link Layer, Network
Layer, Transport Layer, Session Layer, Presentation Layer, Application Layer.
Application Layer : At this layer communication partners are identified where we see some one
to talk to.
Presentation Layer : This is basically part of Operation System where incoming and outgoing
data are changed from one format to another.
Session Layer: This layer basically handles session and conversations/communications where
services include authentication and reconnecting service after interruption.
Transport Layer : This layer manages packetiztion of data, delievery of those packets, checking
for error.
Network Layer : This part is responsible for handling addressing and routing of packets.
Data Link Layer : This setup links between physical networks putting packets into frames.
Physical Layer : This layer communicates, conveys bit stream through network.
d) The protocols that work on transport layer are UDP(User DataGram Protocol),
TCP(Transmission Control Protocol)
e) Logical Address : In terms of memory logical address is the location where an item resides
with the perspective of executing program.
Physical Address : Its the actual address or location residing in memory which is defined in
binary form.
g) The Network Layer impleme.
The Transmission Control Protocol and Internet Protocol Layers .docxrhetttrevannion
The Transmission Control Protocol and Internet Protocol Layers refers to the communication protocols that enable use to do anything over the internet. There are four layers. In the Network Interface Layer things like sending information between hosts on the same local network and translating data from higher layers are done. The layer right above that would be the Internet Layer where data is packaged into packets, receive incoming packets of data, and addressing and transmitting packets occur. Then there is the Transport Layer this layer is responsible for end-to-end communication on the network. In short, the transport layer collects message segments from the application and transmits the to the nest layer.
Physical Layer – hubs, cables, modems, and repeaters.
Data Link Layer – bridges, switches, NIC’s,
Network Layer – routers, brouters
Transport Layer – gateways, firewalls,
Application Layer – PC’s, smartphones, servers
The TCP/IP Protocol suite was developed in the 1960’s and recognized throughout the world after 1983. As for the OSI reference model it was also recognized throughout the world in 1983. Some key similarities between the TCP/IP and OSI Model is that they describe how data is transmitted between devices on a network. Both models also divide the networking concepts into layers. The ideas about how data is broken down into smaller pieces and passed from layer to layer is the same as well. Another similarity is that these models are used to troubleshoot various networking problems. Both are modular and each layer represents a separate set of functions and protocols. Some of the ley differences between the two would be that the OSI model is a more elaborated model where each layer has separate functionality. Unlike the TCP IP model, it does not combine any layers. The OSI has 7 layers, and the TCP IP has 4 layers. The TCP/IP model is more geared towards networking hardware and software used on the internet as to the OSI models is more general and can be applied to any type of network.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

3. THE OSI MODEL
Established in 1947, the International Standards Organization (ISO) is a
multinational body dedicated to worldwide agreement on international
standards. An ISO standard that covers all aspects of network
communications is the Open Systems Interconnection (OSI) model. It
was first introduced in the late 1970s.
Layered Architecture
Peer-to-Peer Processes
Encapsulation
Topics discussed in this section:
8. LAYERS IN THE OSI MODEL
In this section we briefly describe the functions of each layer in the OSI
model.
Physical Layer
Data Link Layer
Network Layer
Transport Layer
Session Layer
Presentation Layer
Application Layer
Topics discussed in this section:
10. The physical layer is responsible for movements of
individual bits from one hop (node) to the next.
11. Physical layer
• Type of transmission media
• Representation of bits
• Data rate
• Synchronization of bits
• Line Configuration
• Topology
• Transmission mode
34. TCP/IP PROTOCOL SUITE
The layers in the TCP/IP protocol suite do not exactly match those in
the OSI model. The original TCP/IP protocol suite was defined as
having four layers: host-to-network, internet, transport, and application.
However, when TCP/IP is compared to OSI, we can say that the TCP/IP
protocol suite is made of five layers: physical, data link, network,
transport, and application.
36. ADDRESSING
Four levels of addresses are used in an internet employing
the TCP/IP protocols: physical, logical, port, and specific.
Physical Addresses
Logical Addresses
Port Addresses
Specific Addresses
39. Comparison of the OSI and TCP/IP Reference
Models
Functionality of the layers is roughly similar
Concepts central to OSI model
• Services : The service definition tells what the layer does, not how entities
above it access it . It defines the layer's semantics.
• Interfaces : tells the processes above it how to access it. It specifies what
the parameters are and what results to expect
• Protocols: the layer's own business.
40. Comparison of the OSI and TCP/IP
Reference Models
OSI reference model was devised before the corresponding protocols were
invented. This ordering means that the model was not biased toward one
particular set of protocols
In TCP/IP, the protocols came first, and the model was really just a
description of the existing protocols
Number of layers: the OSI model has seven layers and the TCP/IP has four
layers.
The TCP/IP model has only one mode in the network layer (connectionless)
but supports both modes in the transport layer.
