Tech myths you need to stop believing



Just like having to believe that when its raining and sunny at the same time a Lion or a wild beast in the forest is giving birth everyday gadget and devices come with lots of dated and bad advice. Most people will be surprised by at least one of these myths, which is why I’ve listed them below.

Don’t be embarrassed if you’ve been doing these things religiously, because they’re widely held beliefs, and many have an iota of truth. But you may also be relieved to learn that they’re inaccurate. After all, even technophiles have their superstitions.

Turn down your phone’s brightness to extend battery life.
You’ve probably heard that adjusting the brightness of your screen to the lowest setting is the best way to save battery power. Although it’s true that reducing the brightness can help, it’s not the best solution. It’s better to use your phone’s “Auto Brightness” setting.
Auto Brightness makes your phone’s display adjust to different lighting conditions. The next time it’s dark outside, you won’t be tempted to crank the brightness up. And this gradual, controlled change actually saves battery life.
The brightness of your screen isn’t the only thing contributing to your depleting battery power. Your phone is constantly downloading information, whether it’s to check email, show ads on a site, update an app or stream music. You can take control.

What is a Li-Fi? Meet the latest technology 100 times faster than Wi-Fi

 Li-Fi 

Light Fidelity (Li-Fi) is a bidirectional, high-speed and fully networked wireless communication technology similar to Wi-Fi. The term was coined by Harald Haas and is a form of visible light communication and a subset of optical wireless communications (OWC) and could be a complement to RF communication (Wi-Fi or cellular networks), or even a replacement in contexts of data broadcasting.

Technology details

This OWC technology uses light from light-emitting diodes (LEDs) as a medium to deliver networked, mobile, high-speed communication in a similar manner to Wi-Fi.The Li-Fi market is projected to have a compound annual growth rate of 82% from 2013 to 2018 and to be worth over $6 billion per year by 2018.
Visible light communications (VLC) works by switching the current to the LEDs off and on at a very high rate, too quick to be noticed by the human eye. Although Li-Fi LEDs would have to be kept on to transmit data, they could be dimmed to below human visibility while still emitting enough light to carry data. The light waves cannot penetrate walls which makes a much shorter range, though more secure from hacking, relative to Wi-Fi. Direct line of sight is not necessary for Li-Fi to transmit a signal; light reflected off the walls can achieve 70 Mbit/s.
Li-Fi has the advantage of being useful in electromagnetic sensitive areas such as in aircraft cabins, hospitals and nuclear power plants without causing electromagnetic interference. Both Wi-Fi and
