The Internet of Things (IoT) is a network of physical objects or "things" embedded with electronics, software, sensors, and network connectivity that allow these objects to collect and exchange data.
Why IoT?
With the development of technologies like M2M (machine-to-machine communication) and widespread of Internet, communication over long distance became possible.
This useful exchange of information across the globe with minimal human intervention led to an innovative concept called Internet of Things (IoT) where objects represent themselves as a digitally forming large network of connected devices that can communicate over the internet.
Components comprising IoT
IoT Hardware – These include sensors, micro-controller devices for control, servers, an edge or gateway.
IoT software – It includes mobile and web applications that are responsible for data collection, device integration, real-time analysis and application and process extension.
IoT Lifecycle
Collect: The life cycle of IoT starts with collecting data from different sources deployed in a particular region. These sources could be any sensors or device capable of transmitting data connected to a gateway. Data are efficiently collected and passed forward through a communication channel for analysis.
Communicate: This phase involves secure and reliable transfer of data. Routers, switches and firewall technologies play a vital role in establishing communication between devices. The Data is sent to the cloud or other data centers using the internet which is our major means of communication in IoT.
Analysis: This phase is an important part of the IoT lifecycle. In this phase data collected from different sensor devices are collected and analysed based on the use case to extract some useful output/information.
Action: This is the final stage of IoT lifecycle. Information obtained by the analysis of sensor data is acted upon and proper actions and measures are taken based on the analysis result.

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

How to Internet of Things Works
Top internet-of-things (IOT) examples to know
Conclusion
3. Internet of thing is simple concept of basically controlling different
device by establishing a connection and computing from mobile
app and web browsers.
The Internet of things (IOT) describes devices with sensors,
processing ability, software and other technologies that connect
and exchange data with other devices and systems over the
Internet or other communications networks. The Internet of things
encompasses electronics, communication and computer science
engineering.
4. The Internet of Things (IOT) describes physical objects embedded with
sensors and actuators that communicate with computing systems via
wired or wireless networks—allowing the physical world to be digitally
monitored or even controlled.
The term Internet of Things generally refers to scenarios where network
connectivity and computing capability extends to objects, sensors and
everyday items not normally considered computers, allowing these
devices to generate exchange and consume data with minimal human
intervention.
5. Big Data Analytics.
Big data analytics refers to the methods, tools, and applications used
to collect, process, and derive insights from varied, high-volume, high-
velocity data sets. These data sets may come from a variety of
sources, such as web, mobile, email, social media, and networked
smart devices.
Embedded system.
Embedded systems use the communication ports to transmit data
between the processor and peripheral devices -- often, other
embedded systems -- using a communication protocol. The processor
interprets this data with the help of minimal software stored on the
memory.
6.
7. The concept of combining computers, sensors, and networks to monitor
and control devices has existed for decades. The recent confluence of
several technology market trends, however, is bringing the Internet of
Things closer to widespread reality. These include Ubiquitous
Connectivity, Widespread Adoption of IP-based Networking, Computing
Economics, Miniaturization, Advances in Data Analytics, and the Rise of
Cloud Computing.
8. • Wireless sensor networks.
Wireless Sensor Network (WSN) is an infrastructure-less wireless network
that is deployed in a large number of wireless sensors in an ad-hoc manner
that is used to monitor the system, physical or environmental conditions.
• Cloud computing
The practice of using a network of remote servers hosted on the internet
to store, manage, and process data, rather than a local server or a personal
computer.
Form of Internet-based computing, whereby shared resources, software
and information are provided to computers and other devices.
9.
10. A sensor is a device that produces
an output signal for the purpose of
sensing a physical phenomenon.
In the broadest definition, a
sensor is a device, module,
machine, or subsystem that detects
events or changes in its
environment and sends the
information to other electronics,
frequently a computer processor.
11. Sensor in every device
Every device emits data regarding working states of things
