Li-Fi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for communication. It can be thought of as a light-based Wi-Fi, transmitting data through illumination by using LED light bulbs that vary in intensity faster than the human eye. Li-Fi works by switching LED bulbs on and off within nanoseconds, too quick for the human eye to detect, and is capable of speeds up to 70 Mb/s. Potential applications include use in hospitals, airplanes, underwater, and other places where radio waves are restricted or pose health risks. Li-Fi offers advantages over Wi-Fi such as higher speed, more secure communication, lower cost, and no health hazards from

Light Fidelity is an emerging trend of Internet distributions. With speeds such as 100GBPS, it will be no less than a boon for the regular internet users. Lifi is a substitute of wifi where the internet is distributed to customers via lights, even if they are visibly off to the naked eye.

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.
# 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

• conclusion
• References
3. • In simple terms, Li-Fi can be thought of as a light-based
Wi-Fi.
• That is, it uses light instead of radio waves to transmit
information.
• Li-Fi would use transceiver-fitted LED lamps that can
light a room as well as transmit and receive information.
4. • The technology truly began during
the 1990’s in countries like Germany ,
Korea and Japan where they
discovered LED’s could be retrofitted
to send information. Harald Hass
continues to wow the world with the
potential to use light for
communication.
• He demonstrated it in the year 2012
5. WHAT IS LI-FI ?
• Li-Fi is a transmission of data
through illumination, i.e sending
data through a LED light bulb
that varies in intensity faster
than human eye can follow.
• Li-Fi –LIGHT FIDEALITY
6. How Li-Fi works:
• The Li-Fi technology light
from LEDs as a medium to
deliver networked mobile,high-
speed communication in a
similar manner of Wi-Fi.
• Li-Fi(VLC) work by switching
bulbs on and off within
nanoseconds,which is too quick
to be noticed by the human eye
and achieve 70mb/s.
8. WI-FI VS LI-FI:
• Li-Fi can be thought of as a light
based Wi-Fi i.e, it uses light instead
of radio waves transmit information.
• Instead of Wi-Fi modems, Li-Fi
would use transceiver – fitted LED
lamps that can light a room as well
as transmit and receive information.
• Li-Fi is more secure than Wi-Fi.
9. • Hospitals
• Airlines
• On ocean bed
• Street lamps
• Traffic lights
• Intrinsically safe environment
10. • Solve insufficiency of radio frequency
• Speed
• Secure
• Low cost
• Safe to human
• Multi user communication
ADVANTAGES:
11. • The possibilities are numerous and can be explored further.
• This technology in which LED is working like a Wi-Fi
