Deep web and dark web??

Did you access your email or facebook or twitter or used drop-box today? If you did any one of those, then you accessed the deep web. The deep web isn’t some mysterious place, it’s just a collection of users private data. It’s hidden because we don’t want anyone to access our private information through facebook or twitter or data on dropbox.

It was estimated that the deep web is about 95% of all the data available online!!

The dark web is similar to the deep web in the respect that it is hidden from the normal web. However the dark web is not information that is not linked, rather it is purposely hidden. To access the dark web you need to use special tools like Tor or Freenet. These are the only ways to get to this hidden content. Though the deep web makes up 95% of all the internet the dark web only consist of about .03%. But that small section has millions of monthly users. The dark web is usually what people actually mean when they refer to the deep web.

 Deep web and Dark web aren’t same. The deep web is on the internet that has the stuff on the internet that can’t be accessed by our traditional search engines like Google. “Dark Web” on the other hand is a term used to describe areas on the internet accessible only through some softwares like TOR. It is the encrypted network that exists between TOR  servers and their clients. As the dark web is pretty much hidden, it is also used for some illegal things. But i have read that the dark web was created by US Navy for transmitting secured information.

What is Internet of Things?

Internet of things is all about objects connecting to the internet. A decade ago, maybe we only have one device connected to the internet, but now we have a plenty of devices like computer, smartphone, tablet, smart watches, cars, TVs, also more advanced home equipment so called smart homes, connected to the internet which work hand in hand.

Internet of things is growing rapidly, if you are following the CES 2016 going on right now, there are so many Internet of things related stuff going on like the Smart refrigerators, which is connected to the internet and notifies us with more useful stuff going on in the refrigerator and many more.

This is like, when you enter your smart home using an app sitting on your smart phone, your smart home senses everything you are up to, like the temperature outside, your schedule through your calendar, your mood etc and acts accordingly.

In near future Artificial Intelligence may further increase it’s reach and help us making suggestions!! For example, In automobile industry, vehicles can predict Absolutely anything with the use of Artificial Intelligence.

Is Artificial Intelligence really necessary? “Smart( indirectly AI)”, why do we like this word so much? Why are we more worried about this particular field this much? We are experiencing more and more revolutionary things, When can we expect an Evolution of new ones, in this field? Maybe a substitute to the Internet?;)

 

What’s Li-Fi? How’s that 100 times faster than Wi-Fi?


Scientists achieved speeds of 224 gigabits per second in the lab using Li-Fi!! This technology changes everything about the way we use the Internet.

And now, scientists have taken Li-Fi out of the lab for the first time, trialling it in offices and industrial environments in Tallinn, Estonia, reporting that they can achieve data transmission at 1 GB per second – that’s 100 times faster than the Wi-Fi used on this day.

Let’s see how this thing works?

The technology uses Visible Light Communication (VLC), a medium that uses visible light between 400 and 800 terahertz (THz). It works basically like an incredibly advanced form of Morse code – just like switching a torch on and off according to a certain pattern can relay a secret message, flicking an LED on and off at extreme speeds can be used to write and transmit. These flicking light falls on a receiver which interprets the data (interpret in the sense the particular number of blinks per second has a significant data like a number or a word)

And while you might be worried about how could we feel comfortable with all that flicking, don’t worry – we’re talking LEDs that can be switched on and off at speeds imperceptible to the naked eye.  The frequency will be extremely high.

There are so many advantages with Li-Fi over Wi-Fi. One of those advantages is, the data will be secure, unlike Wi-Fi where the radio waves passes through walls, in Li-Fi the light cannot pass through walls so data cannot be accessed by anyone else the other side. Which also means there’s less interference between devices.

Don’t get hurry searching the internet to order a Li-Fi connection;). Our homes, offices, and industry buildings have already been fitted with infrastructure to provide Wi-Fi, and ripping all of this out to replace it with Li-Fi technology isn’t particularly feasible, so the idea is to retrofit (add to something that did not have it when manufactured) the devices we have right now to work with Li-Fi technology.

If you wanna learn more watch the video specified above, where the man who invented Li-fi explains and demonstrates what Li-Fi actually is.

So, let me know, what do you think.
