Machine Learning (ML) is a technique of artificial intelligence that gives a computer system the ability to learn from data without being specifically programmed. The term machine learning was coined by Arthur Samuel in 1959. It builds algorithms that can learn from data and make data driven predictions on the basis of inputs made in the past. The computer, software as well as the device performs via cognition which works very similar to the human brain.
Here are some most common applications of Machine Learning that we make in everyday life:
- Virtual Personal Assistant: They act as your personal assistants and help you find information as demanded over voice. Machine learning is a vital part of these personal assistants as they collect, define and predict information on the basis of inputs made in the past. They start recognizing your preferences and show results accordingly.
- Traffic Predictions: Our current location is tracked through GPS navigation, which enables the server to predict current traffic. It will do a congestion analysis and let you know the way you should take to avoid being stuck in traffic. Also it estimates the areas which are more prone to traffic congestion on a daily basis.
- Online Transportation Network: Machine learning plays a major role when it comes to online transportation network. For example, it is only though this technique that when you book a cab, the app estimates price of the ride, minimizes the detours, predicts the price when the demand is high etc.
- Video Surveillance: Nowadays, video cameras are designed in a way that makes it possible to detect & prevent any crimes. Machine learning enabled system keeps a track of any unusual activity or behavior & alerts the human attendants if there is something suspicious to help in preventing it.
- Social Media Services: Social media platforms are also using machine learning. It is being used for effectively targeting ads, personalizing the news feed, recognizing the face when you upload your and a friend’s picture, suggesting people you may know on the basis of friends you connect to, profiles you visit, interests you share, etc.
- Online Customer Support: Websites nowadays give people an option to chat with their customer support representative or a chatbot while scrolling through it. The chatbot is able to understand user queries only due to the machine learning algorithms.
- Product Recommendations: Machine learning enables websites & apps to personalize the customer experience and make recommendations as per your taste. It understands the behavior, brand preferences and shows you the results accordingly.
- Online Fraud Detection: It has helped in increasing cyber security by tracking & preventing monetary frauds such as money laundering etc.

- Numerous toolbars on the web browser which have not been installed by the user.
- Inability to access necessary data.
- Very less browser security.
- Sites being blocked.
- Web queries that fail to proceed through search engines.
How To Remove Browser Hijacking?
- Check out the authenticity of browser add-ons, plug-ins, extensions etc.
- Remove anything that seems suspicious or unnecessary from the system’s browser.
- Reset the browser settings to original default.
- Clear off the system’s Domain Name System (DNS) cache.
- Use browser hijacker removal tools
How To Prevent Browser Hijacking?
Following are some ways to prevent browser hijacking in the first place:
- Regularly update operating system (OS) as well as browser patches.
- Make sure that the browser software is updated with latest security features and are devoid of any vulnerabilities.

Li-Fi i.e. Light Fidelity is a revolutionary wireless optical networking technology. It uses light-emitting diodes for data transmission. The LED light bulbs that have a chip that modulates light imperceptibly for optical data transmission. Data is transmitted by LED bulbs which is then received by photoreceptors. It is much more efficient & secure than typical wireless technologies.
The term LI-Fi was coined by Harald Hass, a professor from University Of Edinburgh during a TED talk in 2011. The primary difference between Wi-Fi and Li-Fi is that the former runs on radio waves whereas the latter uses light waves.
How Does It Work?
The intensity of light is modulated either by dimming it, turning it on and off at a very high speed to transmit data over Li-Fi. These changes are generally imperceptible to the human eye.
An LED with signal processing technology is fitted over an overhead lamp. The data which is embedded in its beam is streamed to the photo detector. The data is demodulated in electronic form by a dongle at the receiver’s node. It is then converted back into a data stream and transmitted to a computer or mobile device.
Li-Fi is 100 times faster than normal wireless technologies with a speed of 224 gigabytes per second under lab conditions.
Benefits Of Li-Fi
- Due to high speed, the data transfer rate for internet application is high.
- As light cannot pass through the walls & opaque surfaces, sending data through Li-Fi signal is highly secure. This is because Li-Fi internet is available to users within a room which thus prevents its unwanted access.
- It is highly efficient technology which consumes very less energy.
- Li-Fi devices consume very little power.
- Completely safe & has no health concerns associated with it as it operates on optical bands.
- Helps in avoiding neighboring network interference.
Applications Of Li-Fi
- Military – Li-Fi is highly secure even though it is confined to a small range which makes it ideal for military use in remote areas. It is does not require much physical infrastructure because all it needs is light.
- Underwater Communications – Radio waves cannot travel through water whereas light can. So it can be used by underwater vehicles & divers to communicate with each other under water.
- Augmented Reality – It is generally used in museums & galleries. Through this people can download or view information regarding the object being viewed from the light on their phone or camera.
- Safety Environment – Li-Fi can be extremely helpful to transfer data in explosion hazard environments where other electrical equipment’s are restricted.
- Intelligent Transportation Systems – LED lights are widely being used in car headlights these days. It is being used in traffic lights and also to develop anti-collision systems. It enables your car system to get real time information from the network.
So, the technology is based on visible light communication. With speed as much as 100 times faster in testing than other wireless technologies, it is a perfect fit for data requirements of future.
