This presentation discusses different network topologies. It introduces the topic of network topology and defines physical and logical topologies. It then describes and compares the advantages and disadvantages of several common topologies: bus, star, ring, mesh, and hybrid. For each topology there is a discussion of how it works and an analysis of its pros and cons in terms of ease of use, cost, reliability, and other factors. The overall presentation provides a high-level overview of key network topology types.

Topology is the arrangement of the various elements of a computer network.
In communication networks, a topology is a usually schematic description of the arrangement of a network, including its nodes and connecting lines.
A computer network is made of computers which are linked to one another with communication lines (network cables, etc.) and hardware elements (network adapters, as well as other equipment for ensuring that data travels correctly.
Parallel Mode is the way the internal transfer of binary data takes place inside a computer.
Serial Mode is the predominant method of transferring information in data communications.

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.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

5. Network topology
Network topology :
In communication networks, a topology is a usually schematic
description of the arrangement of a network, including its nodes and
connecting lines. There are two ways of defining network geometry:
the physical topology and the logical (or signal) topology.
6. Bus topology:
In this type of topology, all the nodes are connected to the single cable
(called bus), by the help of interface connectors. This central cable is
the backbone of the network and is known as Bus . Every workstation
communicates with the other device through this Bus.
7. Advantage & disadvantage of bus topology:
>>Advantage:
1) It is easy to set-up and extend bus network.
2) Cable length required for this topology is the least compared to other networks.
3) Bus topology costs very less.
>>Disadvantage:
1) There is a limit on central cable length and number of nodes that can be connected.
2) Maintenance costs can get higher with time.
3) It is not suitable for networks with heavy traffic.
4) Security is very low because all the computers receive the sent signal from the
source.
8. Star topology:
In Star topology, all the components of network are connected to the
central device called “hub” which may be a hub, a router or a switch. Unlike
Bus topology , where nodes were connected to central cable, here all the
workstations are connected to central device with a point-to-point
connection. So it can be said that every computer is indirectly connected to
every other node by the help of “hub”.
9. Advantage & disadvantage of star topology:
>>Advantage:
1) Easy to connect new nodes or devices.
2) Failure of one node or link doesn’t affect the rest of network. At the same
time its easy to detect the failure and troubleshoot it.
>>Disadvantage:
1) Too much dependency on central device has its own drawbacks. If it fails
whole network goes down.
2) The use of hub, a router or a switch as central device increases the overall
cost of the network.
3) Performance and as well number of nodes which can be added in such
topology is depended on capacity of central device.
10. Ring topology :
In ring topology, each computer is connected to the next computer and
the last computer is connected to the first. Thus, a ring of computers is
formed.
11. Advantage & disadvantage of ring topology:
>>Advantages:
1) It is less expensive than star topology.
2) It is easy to install and to maintain.
3)All computers have equal access to the network.
>>Disadvantages:
1) If one node fails, it affects the entire network.
2) Adding or removing a computer in the network affects the whole network.
12. Mesh topology:
In mesh topology, each node is directly connected to every other node
on the network. This type of network involves the concept of routes.
Mesh topology is rarely used in LAN. Some WANs like the Internet use
mesh topology.
13. Advantage & disadvantage of mesh topology:
>>Advantages:
1) Data can be transmitted from different devices simultaneously. This topology can
withstand high traffic.
2) Even if one of the components fails there is always an alternative present. So data
transfer doesn’t get affected.
3) Expansion and modification in topology can be done without disrupting other nodes.
>>Disadvantages:
1) There are high chances of redundancy in many of the network connections.
2) Overall cost of this network is way too high as compared to other network topologies
3) Set-up and maintenance of this topology is very difficult.
14. Hybrid topology :
A hybrid topology is a network topology that uses two or more network
topologies.
15. Advantage & disadvantage of hybrid topology:
>>Advantage:
1) Unlike other networks, fault detection and troubleshooting is easy in this type of
topology.
2) Its easy to increase the size of network by adding new components, without disturbing
existing architecture.
>> disadvantage:
1)Configuration and installation process is vey difficult.
2)The hubs used to connect two distinct networks, are very expensive.
