What is Networking?
A computer network is defined as the interconnection of two or more computers. It is done to enable the computers to communicate and share available resources.
Application:
• Sharing of resources such as printer.
• Sharing of expensive software's and database.
• Communication from one computer to another computer.
• Exchange of data and information among users via network.
• Sharing of information over geographically wide areas.

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.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

3. DEFINTION :
A computer network is defined as the interconnection of two
or more computers systems or peripheral devices ,to enable
the computers to communicate and share available
resources.
ITS COMPONENTS:
Two or more computers.
Cables as links between the computers.
A network interfacing card(NIC) on each computer.
Connecting devices.
Networking operating system
A Protocol suite.
4. ADVANTAGESOFNETWORKING
Sharing of hardware :like printers, fax, scanners.
Sharing of software :like sharing software resources
reduces the cost of software installation and space on
hard disk.
Sharing file: which increases teamwork and productivity.
Easy to take backup since data is stored on one computer
called server.
Cost effective method.
Saves time.
5. DISADVANTAGES OF NETWORKS
High cost of installation.
Requires time for administration.
Failure of server may cause network breakdown.
Cable faults may interrupt connectivity.
Security from hackers should be monitored with
software programs like firewalls.
Viruses can harm the network ,antivirus programs
should be used .
7. PEER TO PEER(P2P) NETWORK
Computers or nodes are connected with other
computers to share resources and accessing files..
Computer is responsible for setting up and
maintaining its own security.
Useful for a small networks less than 10 computers on
a single LAN .
Computer functions as both client and server. It has
no server.
Less expensive.
8. CLIENT/SERVERNETWORK
Server: It is a powerful central computer which has most of
the network resources and provide services to other
computers when they request it. Server provide security and
administration to the network.
Client : A client is the computer running a program that
requests the service from a server.
Local area network(LAN) is based on client server network
relationship.
Front-end: software which user sees and interacts directly.
Back-end :Interacts with shared resources such as
databases, printers or high power processors.
More expensive than P2P.
9. SWITCHING TECHNIQUE
In large networks there are multiple paths linking the
sender and receiver. Selecting a path that data must take
out of the available options is switching.

Packet
Switching
10. • Connects sender and receiver within an unbroken path.
• A dedicated path exists between the two ends unless
communication is terminated.
• Appropriate for immediate data transfer like telephone line.
CIRCUIT SWITCHING
11. • Message is treated as independent unit and it is send
through series of nodes.
• Each node receives the message stores it and then
transmits it also known as storage-and-forward network.
• Channel efficiency is high because more device are
sharing the channel.
• Traffic congestion is reduced because message is
temporarily stored in the node.
MESSAGE SWITCHING
12. • Message is broken into a series of packets.
• Each packet contains header contains information
about source ,destination and reassembling
instruction.
• Each packet takes different routes to reach
destination.
• Founds in large networks Like TCP/IP protocol uses
it.
PACKET SWITCHING
13. TYPES OF NETWORKS
NETWORK
PAN LAN MAN WAN CAN
A network is ‘interconnected’ computers i.e. they
are linked by any communication system.
Networks vary in size, complexity and
geographical spread.
14. PERSONAL AREA NETWORK(PAN)
Organized around an individual person.
Communication capable devices like mobile computer,
a cell phone or personal digital assistant.
Wireless or cables.
Range up to 10 meters.
15. LOCAL AREA NETWORK(LAN)
Designed to operate over a small physical area such
as an office, factory or a building.
All machines are connected to a single cable .
Easy to design and troubleshoot.
Exchange of information and sharing of resources
becomes easy.
Different types of topologies such as star, tree, bus,
ring, etc. can be used.
It is usually a privately owned network.
16. METROPOLITAN AREA NETWORK(MAN)
It covers the entire city.
It uses similar technology as LAN.
It can be a single network such as cable TV network.
It is a measure of connecting number of LAN’s on a
large network so that resources can be shared
LAN to LAN as well as device to device.
17. WIDE AREA NETWORK(WAN)
When network spans over a large distance or connected
computers are at widely separated locations then it is
WAN.
Connections through public networks like telephone
lines, leased telephone lines, satellite links and
similar channels done.
It is cheaper and more efficient.
WAN networks are used to transfer large blocks of data
between its users.
INTERNET is the largest WAN network in existence.
18. CAMPUS AREA NETWORK(CAN)
The campus area network is made up of an
interconnection of LAN with limited geographical area.
Network equipments such as switches, routers and the
transmission media i.e. optical fibre etc are almost
entirely owned by the campus owner.
