The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

3. A computer network, or simply a
network, is a collection of computers and
other hardware components
interconnected by communication
channels that allow sharing of resources
and information.
A network provides two principle benefits:
the ability to communicate and the ability
to share.
A network can consist of two computers
connected together on a desk or it can
consist of many Local Area Networks
(LANs) connected together to form a Wide
Area Network (WAN) across a continent.

4. Types of
Computer
Network
LAN: A group of interconnected computers
under one administrative control group.
WAN: A networks that connects LANs in
Geographically separated locations.
WLAN: Group of wireless devices that
connect to access points within a specified
area.
MAN: metropolitan area network falls in
middle of LAN and WAN, It covers large
span of physical area than LAN but smaller
than WAN, such as a city.
SAN: Storage area network connects servers
to data storage devices .
CAN: Campus Area Network

5. Physical topology refers to the placement
of the network's various components,
including device location and cable
installation, while logical topology shows
how data flows within a network,
regardless of its physical design
6. Peer-to-peer networks:
Devices which are connected
directly to each other without any
additional networking devices
between them. Each device has
equivalent capabilities and
responsibilities.
Client Server network:
In a client/server model, the client
requests information or services
from the server. The server provides
the requested information or service
to the client.
Physical Types of Network
7. Network topology is the arrangement of
the various elements (links, nodes, etc.)
of a computer or biological
network. Essentially, it is the
topological structure of a network, and
may be depicted physically or logically.
10. Network
Hardware
Physical topology refers to the placement
of the network's various components,
including device location and cable
installation, while logical topology shows
how data flows within a network,
regardless of its physical design.
13. Network
Devices
Computer networking devices are units that
mediate data in a computer network. Computer
networking devices are also called network
equipment, Intermediate Systems (IS) or Inter
Working Unit (IWU).
LAN Equipment
o Network Cards
o Repeaters
o Hub
o Switch
o Bridges
WAN Equipment
o Routers
14. Network Card
A network interface controller (also
known as a network interface card,
network adapter, LAN adapter and by
similar terms) is a computer
hardware component that connects a
computer to a computer network.
LAN Equipment
15. Repeater
A repeater is an electronic device
that receives a signal and retransmits
it at a higher level or higher power, or
onto the other side of an obstruction,
so that the signal can cover longer
distances.
LAN Equipment
16. Hub
An Ethernet hub, active hub, network
hub, repeater hub, multiport
repeater or hub is a device for
connecting multiple Ethernet devices
together and making them act as a
single network segment.
A hub works at the physical layer
(layer 1) of the OSI model.
LAN Equipment
17. Switch
A switch is a telecommunication device which receives a message from any
device connected to it and then transmits the message only to the device for
which the message was meant. This makes the switch a more intelligent
device than a hub (which receives a message and then transmits it to all the
other devices on its network).
LAN Equipment
18. Bridge
Network bridging describes the
action taken by network equipment
to allow two or more communication
networks, or two or more network
segments creating an aggregate
network. Bridging is distinct from
routing which allows the networks to
communicate independently as
separate networks
LAN Equipment
19. Router
A router is a device that forwards data
packets between computer networks,
creating an overlay internetwork. A
router is connected to two or more
data lines from different networks.
When a data packet comes in one of
the lines, the router reads the address
information in the packet to determine
its ultimate destination. Then, using
information in its routing table or
routing policy, it directs the packet to
the next network on its journey.
WAN Equipment
20. Internet
Protocol
Network Protocols are the formal
description of a set of rules and
conventions that govern how devices on
the network layer (layer 3 of the OSI
model) exchange information.
Protocols provide the link by which
systems connected to a network may talk
to each other
For two end systems to talk to each other,
they must effectively “speak the same
language traffic”
21. An Internet Protocol address (IP address)
is a numerical label assigned to each
device (e.g., computer, printer)
participating in a computer network that
uses the Internet Protocol for
communication. An IP address serves two
principal functions: host or network
interface identification and location
addressing.
22. IP Address
