Difference between LiFi and WiFi Wi-Fi(wireless fidelity)  and  Li-Fi(light fidelity)  both are two different technologies which are  used to send and receive data wirelessly . In case of Wi-Fi we use Routers and Radio Frequency (RF) waves to transmit data, whereas in Li-Fi we use LED bulbs and Light signals to transmit and receive data. Basic Difference between LiFi and WiFi: COMPARISON LI-FI WI-FI Full form stand for light fidelity stands for wireless fidelity Invented/Coined Coined by Prof. Harald Haas in 2011 By NCR corporation on 1991 Operation it transmits data using light by the help of LED bulbs it transmits data using radio waves using wifi router Technology Present IrDA compliant devices WLAN 802.11/b/g/n/ac/d standard compliant devices Data Transfer Speed About 1 Gbps Ranges from 150Mbps to maximum of 2Gbps Privacy light is blocked by the walls hence provide more secure data transfer walls cannot block radio waves so we need to employ more techniques to ac...

Excellent example of focusing on the right thing: During World War II, the Allies mapped bullet holes in planes that were hit by Nazi fire. They sought to strengthen the planes, reinforce areas heavily damaged by enemy artillery to be able to withstand these battles even more. The immediate decision was to rebuild and reinforce areas of the plane that had more red dots (or received more bullets). Theoretically, it was a logical deduction. After all, these were the most affected areas. But Abraham Wald, a mathematician, came to a different conclusion: the red dots represented only the damage to the planes that were able to return, that came home. The areas that really should reinforce, were the places where there were no points because these are the places where the plane would not survive being hit. This phenomenon is called survival deviation. It happens when you look at the things that have survived when you should focus on the things you don't. What are you looking at in this cr...

Is McDonald's a burger company or a real estate empire? McDonald's operates a Franchise model. Back in the '50s, a Franchisee (any willing entrepreneur) would select a piece of land in a prime location, lease it, & then construct a McDonald's outlet on here. McDonald's, on the other hand, provides the brand, recipe, tools and other operational know-how. For its efforts, McDonald's gets a % commission on the sales. The franchise model helped McDonald's scale rapidly. But profitability took a hit. There's not a lot of money you can make from a 2% commission on burgers. Until a finance executive forced Ray Kroc (the eventual owner of McDonald's) to notice the bigger picture. His contention was that the one thing more important than the burgers was the land on which these burgers were made. He convinced Ray Kroc to buy plots of land & lease it to Franchisees instead of letting them pick it on their own. This helped the company extract an upfront ...
