LiFi Technology - Faster transmission technology in world

LiFi stands for light fidelity. It is a wireless optical networking technology and it uses light emitting diode for data transmission. Its close similar to Wi-Fi, but it uses light instead of radio waves. Which make it so special. LiFi can be up to 100 time faster than WiFi. It uses light to transmit data, which give it advantages of working in areas which is susceptible to electromagnetic interference. The light wave cannot penetrate the walls which translates to much shortage range, and lower hacking potential compare to WiFi.

HOW LI -FI WORKS ?

LiFi works on a Visible Light Communication system. VLCs works by switching the current to LEDs off at very high speed. The technology made LED light bulb emit pulses which is undetectable to human eye and with those limited pulse, data can travel to and from receivers. The receiver than collect data and then interpret them. LiFi can touch the transmission speed at 100Gbps 14 times faster than WiGig, the fastest WiFi in world. Data is captured in modulated light frequency of a solid state LED light source and is then transmitted and received by LiFi enabled devices. A photosensitive detector demodulates the light frequency signal and converts it back in electronic data stream.

RPA - UiPath

What is RPA? RPA (Robotic Process Automation) is technology which let organization to make their task easy by allowing them to automate the task just like a human being was doing them across application and systems. The purpose of RPA is to transfer the process execution from humans to bots. Robotic process automation interacts with the existing IT architecture with no complex system integration required. UiPath - The vendor UiPath is a New York City-based global software company that develops a platform for robotic process automation (RPA). The company's software monitors user activity to automate repetitive front and back office tasks, including those performed using other business software such as customer relationship management or enterprise resource planning (ERP) software. UiPath develops software to automate repetitive digital tasks normally performed by people. The technology combines emulating how humans read computer screens (AI Computer Vision) with APIs...

Some Pseudoscience and myths we still believe

Hi frnd, In this post I have mentioned some science fact and myth, among which some myth are not properly proof by science yet. But we still used to believe in that. That are also known as Pseudoscience. Bad Small Can Make You Sick According to the once-popular miasma theory, diseases were caused by "bad air." Miasma is the name for this foul-smelling, poisonous vapor that carried particles of decaying matter. In 1854, epidemiologists traced a deadly outbreak of cholera to water contamination. Discovering no organic matter in the water that was undoubtedly causing all the cholera, John Snow debunked miasma theory by proving that cholera is a waterborne disease. Soon, germ theory caught on and miasma flew out the window. Diffrent Parts of Tongue Have Different Taste Maybe this is one you learned in school, and maybe even still believe. Sorry, the idea that the tip of your tongue picks up sour tastes, or the middle of your tongue processes sweetness, or whatever, i...

Alien could be discovered on this new class of 'Hycean' exoplanet.

In the discovery for Alien life, astronomers have mostly looked for planets of a similar size, mass, temperature, and atmospheric composition to Earth. Recently, the team of astronomers find a class of planets that may prove the existence of Alien Life. Such exoplanets are more numerous in planetary surveys than rocky ones, which means they could be fertile territory in the search for alien life. The researchers have dubbed them 'Hycean' worlds. In the new study, researchers identify one such class of alien worlds "Hycean" planets, which are up to 2.5 times larger than Earth and feature huge oceans of liquid water beneath hydrogen-rich atmospheres. Hycean planets appear to be incredibly abundant throughout the Milky Way galaxy, and they could host microbial life similar to the "extremophiles" that thrive in some of Earth's harshest environments, study team members said. "Hycean planets open a whole new avenue in our search for life elsewhere,...
