<div style="text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;"><i><b>SP's: </b>Dell Inc. has just bought EMC, a data storage and cloud company for $67 billion, making it the biggest tech deal of all time.</i></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Dell, presently the third largest maker of personal computers, along with its partners, has bought its rival data storage company EMC for $67 billion, making it by far the biggest tech deal of all time. The deal was hitherto rumoured to be around $50 billion.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">However, VMware, the bigger part of the EMC will remain as a separate publicly traded company, but other than that EMC will now accede to Dell. EMC announced that along with Dell, now both these companies will become the world’s largest privately controlled and integrated technology company.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">The deal is also amusing as Dell is almost half the worth of EMC, valuing around $25 billion. Michael Dell, the founder and CEO of Dell Inc. would look over both the companies now.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">The deal will boost Dell to expand and make it more diverse in the services industry. Dell is already quite popular with its personalised computers and now owning a cloud computing and storage facility, will help the company to compete with the likes of HP and IBM, the veterans in business.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">However, amalgaming the work culture of these two giants would be a task for Michael who will succeed Joe Tucci as the CEO of EMC.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Dell has bought EMC for $33.15 a share up from the anticipated $27. So, let’s wait and see if the biggest tech deal in history was worth the risk.</span></div>
<div style="text-align: justify;">

Crazy Amazon Deal: Indian Man Got Brick Instead of OnePlus One

<img alt="OnePlus One replaced-by Brick-Amazon-India" height="478" loading="lazy" src="http://d2brer6wwumtdu.cloudfront.net/wp-content/uploads/2015/10/OnePlus-One-replaced-by-Brick-Amazon-India.jpg" width="640" /></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><i><b>SP's: </b>Amazon India, in its first ever reported incident, sent a man a brick instead of a Rs. 22K OnePlus One. Apparently, the package was violated in the middle of the delivery process.</i></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Now, this would definitely go into the great book of trolls. So, the story is, a man from India ordered a OnePlus One from Amazon. He was eagerly waiting for his sleek brand new smartphone which he would show-off to his friends. Finally, it arrived, 30 hours late (doesn’t matter, the new phone arrived at least). So, the guy opened the neat packing in excitement and bam… he got a piece of brick inside.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Many of us prefer shopping online nowadays, but it happens, rarely though, that you get an unpleasant surprise like this guy did. Maninder Walia, the victim in this obnoxious incident posted his ordeal on Facebook and also commented on Amazon India’s Page.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">You can see the interesting conversation between Maninder and Amazon on<a href="http://www.gadgetgyaan.com/gadgets/man-orders-oneplus-one-amazon-india-sends-brick-3578/" target="_blank"> gadgetgyaan</a>.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">The packaging was tampered and the phone was probably stolen. Amazon has not yet resolved the issue and its customer care had asked Maninder to have patience. Well, you pay Rs. 22K for a phone and you get a brick plus preaching of patience. Nice.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Such incidents have occurred in the past, but this is the first known case with Amazon India. There were instances when people were shocked as they opened up the packaging to find notepads or well, bricks instead of iPhone.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">The OnePlus One is an Android smartphone by the Chinese OnePlus startup. It has a 5.5″ display with 1080 x 1920 pixel resolution, Corning Gorilla Glass 3 protection and powered by Snapdragon 801 processor. The new Snapdragon 801 processors are also being used by Qualcomm for their drones. OnePlus One has a 13 MP rear camera with autofocus and dual LED flash and a 5MP front camera.</span></div>

Pepsi Launching Its First Android Phone. Are You Going to Buy It?

<div dir="ltr" style="text-align: left;" trbidi="on">
<div style="text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;"><i><img alt="Pepsi-phone-android" loading="lazy" src="http://d2brer6wwumtdu.cloudfront.net/wp-content/uploads/2015/10/pepsi.jpg" /></i></span></div>
<div style="text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;"><i><b>SP's: </b>PepsiCo, one of the world’s largest companies, is rumored to launch its own smartphone called Pepsi P1. Read more to know everything.</i></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">There isn’t any typo in the article title. And I’m also not talking about some Chinese electronics company named after your favorite beverage brand Pepsi.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">According to the reports, one of the world’s large companies, Pepsi, is planning to launch it’s first ever smartphone. This is a whole new area for Pepsi, but according to an official Pepsi account spotted on Weibo (also called the Chinese Twitter), an unannounced Pepsi P1 smartphone is in the making.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">It won’t be wrong to expect that Pepsi will be contacting any one of the Asian phone manufacturers, who would happily make phones on behalf of PepsiCo. The leaks look original as the Pepsi Phone Weibo account was linked to the official Pepsi China Weibo account.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: center;">
<img alt="Pepsi-phone-android" loading="lazy" src="http://d2brer6wwumtdu.cloudfront.net/wp-content/uploads/2015/10/Pepsi-phone-android.jpg" /></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">We’re talking about a Chinese smartphone, so it’s hard to tell if it’s something real or just another gimmick. Talking about the price, the Pepsi P1 is priced at $205 in China and it could cost higher in the other countries.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, 'Times New Roman', serif;">Imagining a phone from Pepsi in US and Europe could be a little difficult. But, the Chinese and Japanese markets are more open to such improvisations.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Anyway, let’s see what Pepsi P1 could offer us. The smartphone is running on the Android 5.1 Lollipop operating system and it comes with a full HD 5.5-inch IPS LCD capacitive display.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">The Pepsi phone is powered by a 1.7GHz octa-core MediakTek processor and 2GB of RAM. The phone  is rumored to come with 16GB internal memory.</span></div>
<div style="text-align: justify;">

<div style="text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;"><i><b>SP's: </b>The opinions of Linus Torvalds are weighed quite heavily when it comes to the matters of Linux. Earlier this week, at LinuxCon Europe, the Linux founder expressed his views on the matters of security and the future of ARM powered laptops.</i></span></div>
<div style="text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">According to Linus Torvalds, ARM laptops are the devices of future. “I’m happy to see that ARM is making progress.” He added, “One of these days, I will actually have a machine with ARM. They said it would be this year, but maybe it’ll be next year. 2016 will be the year of the ARM laptop.”</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">At the conference, he answered multiple questions from the Dirk Hondel, Chief Linux and Open Source Technologist at Intel.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Linus Torvalds didn’t mention if he was talking strictly about Linux-based ARM laptops.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">His expectations could be supported by the fact that ARM processor-powered Chromebooks are rising at a very fast pace. Along with that, there are many Linux distributions that have their ARM versions,  including Ubuntu, Debian, Gentoo, Fedora etc.</span></div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Talking about the Linux kernel security, Linus said that it’s very hard to please security experts. “Security people will always be unhappy,” he said. However, he added that he believes the kernel developers are doing their best to check the 25 million lines of kernel code for bugs.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Talking about the progress Linux has made in the previous years, he says that Linux did everything he expected in its first sixth months. He thanked the community by saying that what came after those six months, was the result of other people solving new problems.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">“Linux is all these crazy people doing crazy things I never imagined. It’s going to be interesting to see what others will do with it in the next 25 years,” Linus Torvalds adds.</span></div>

“Psychic Robot”, The Last Piece In The Uprising

Shivam Patsariya 0 Science 11:00 AM

<div dir="ltr" style="text-align: left;" trbidi="on">
<div style="text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;"><i><img alt="psychic robot" loading="lazy" src="http://d2brer6wwumtdu.cloudfront.net/wp-content/uploads/2015/10/Capture1.jpg" /></i></span></div>
<div>
<div style="text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;"><i><b>SP's: </b>Engineers have gone one step ahead in advancing the Artificial Intelligence. The new algorithm, a ‘psychic robot’ would help in predicting the human intent.</i></span></div>
<div style="text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Ok, so till now we all thought that the advanced robots which are self awared and with improved cognition would lead the mutiny, but we just found out who will be the real boss! The Charles Xavier of the robo army, a psychic robot.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Well, the concept could make quite a sci-fi episode, but bio engineers in the US are developing a ‘psychic robot’ for real. The engineers have created a robot that based on our past activity could predict our future pursuits. The algorithm would foretell by looking into our actions even if they are interrupted.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Now, this might not the technical definition of a being psychic, the ability to read minds, but it definitely falls in the category of a prognosticator, predictions based on the current events. This sounds really good if the person is a weather reporter, but for a robot to be able to do that; it is bound to make people uncomfortable.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">To test the state of the art technology, researchers at the University of Illinois at Chicago took a scenario where a person reaching to grab something on his desk would get obstructed. We all could make out of the motion but can a robot do that? Well, reportedly yes, as published in the <a href="http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0137289" target="_blank">study</a>. <i>The software was able to analyze the movement and figured the subject’s intent!</i></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">But, everything is not scary about the technology. This algorithm of predicting intent could be a life savour when you are on the roads. As Justin Horowitz, a research assistant explains, “If we hit a patch of ice and the car starts swerving, we want the car to know where we meant to go. It needs to correct the car’s course not to where I am now pointed, but where I meant to go.”</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">This could be applied to healthcare as well. For a stroke patient, for example, the technology could help the person when his own body corrupts its actions due to spasms or tremors.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">So, the scientists and engineers actually work for the benefit of the humanity (well, most of the time), but the development should be monitored as the last thing humans would want is the slaves becoming the masters.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Now, it would take some more time by to make something that could read human minds, but with the unprecedented pace of developments in Artificial Intelligence, it should not be very far.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">And as for regular people like us, the ‘psychic robot’ could be the best tech for guys- helping you to predict your girlfriend’s intentions, duh!</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">

10 Inventions That Make Nikola Tesla One Of The Greatest Scientists Of All Time

He has made more than 700 inventions and had over 100 patents in his lifetime.</i></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><b>Nikola</b> Tesla, who is one of the greatest scientists of all time obtained more than 100 patents in his lifetime. Despite his 700 inventions, Tesla was not wealthy. He worked in his room for many years, at the Hotel New Yorker, where he died.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Take a quick look at some of this greatest inventions:</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<h3 style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">1. Alternating Current:</span></h3>
<div style="text-align: center;">
<img alt="alternating current" height="514" loading="lazy" src="http://d2brer6wwumtdu.cloudfront.net/wp-content/uploads/2015/10/alternating-current.png" width="640" /></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Alternating current wasn’t invested by Tesla. However, his outstanding contribution in making its usage simple shall always make it one of his greatest inventions. Tesla, who worked for Edison at that time pointed out the flaws and inefficiency of Edison’s direct current electrical powerhouses.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">DC current flows continuously in a direction, where as alternating current be stepped up to very high voltage levels as it changes its direction 50-60 times per second, thus minimizing power loss across great distances. Even after the much bitterness between Edison and Tesla regarding the AC vs DC war, ultimately, Nikola Tesla developed polyphase alternating current system of generators, motors and transformers and held 40 basic U.S. Patents on the system. This was bought by George Westinghouse, which marked the nationwide and thereafter, worldwide usage of electricity.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<h3 style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">2. The Tesla Turbine:</span></h3>
<div style="text-align: center;">
<img alt="testa turbine" height="297" loading="lazy" src="http://d2brer6wwumtdu.cloudfront.net/wp-content/uploads/2015/10/testa-turbine.png" width="640" /></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">In the early 20th century, which was primarily the era of piston engine in automobiles, Tesla invented his own engine in turbine style, which was bladeless  and used made use of smooth discs that spun in a chamber. The fuel efficiency of his engine was 60% (which was a great achievement at that time as the current fuel efficiency level we are at is 42%).</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<h3 style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">3. The Tesla Coil</span></h3>
<div style="text-align: center;">
<img alt="tesla coil" loading="lazy" src="http://d2brer6wwumtdu.cloudfront.net/wp-content/uploads/2015/10/tesla-coil.png" /></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">The Tesla Coil is another of his greatest inventions. It is a high-frequency air-core transformer which takes the output from a 120vAC to several kilovolt transformer & driver circuit and steps it up to an extremely high voltage (above 1,000,000 volts) and are discharged in the form of electrical arcs. Tesla coils create extremely powerful electrical fields, which define their uniqueness.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<h3 style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><b>4. & 5. Radio And Remote Control</b></span></h3>
<div style="text-align: center;">
<img alt="tesla radio" height="410" loading="lazy" src="http://d2brer6wwumtdu.cloudfront.net/wp-content/uploads/2015/10/tesla-radio.png" width="640" /></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Tesla patented a radio controlled robot-boat which was used to control radio waves  in the Electrical Exhibition in 1898. Tesla’s robot-boat was constructed with an antenna, transmitted the radio waves which were again received by coherer.</span></div>

<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Tesla built the largest and most powerful Tesla Coil, called The Magnifying Transmitter. This had three coils and was 52 feet in diameter. What made it the biggest lightning at that time was the fact that it generated electricity of the order of millions of volts and shot lightning bolts (approximately 130 feet long).</span></div>

<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Besides, explaining changes in x-ray characteristics as being caused by variations in x-ray tubes and electrical generators, Tesla also realized the biological hazards of working with unipolar x-ray tubes.</span></div>

<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><b>Is </b>your password safe enough? If you are feeling confident enough, take a minute and read this story. A password-cracking expert has revealed a new computer cluster that can crack any Windows passwords in less than six hours.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">This beast cycles about 350 billion guesses per second and it could use a new virtualization software that gets juice from 25 GPUs (AMD Radeon graphics card). The 64 bit Linux-based GPU cluster runs the Virtual OpenCL cluster platform that allows these graphics cards to work as if they are on a single computer.</span></div>

<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">This means, the cluster can try n mammoth 958 password combinations in just 5.5 hours. This amazing set of tries is enough to brute force every possible 8-character password that can contain digits, upper and lower case letters, and symbols.</span></div>
<div style="text-align: justify;">

What is VPN (Virtual Private Network)? How it Works?

Shivam Patsariya 0 Security 3:50 AM

<div dir="ltr" style="text-align: left;" trbidi="on">
<div style="text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;"><img alt="what-is-vpn" height="368" loading="lazy" src="http://d2brer6wwumtdu.cloudfront.net/wp-content/uploads/2015/10/what-is-vpn.jpg" width="640" /><b>SP's: </b>VPN is a technology used to setup a private network over the internet to share the resources of a corporate intranet with remote users and other office locations of the company. </span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><b>Virtual </b>Private Network or simply VPN is a personal network created over the internet, so that the devices connected over it can have an uninterrupted communication, regardless of any physical or digital barriers in the mid-way.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">How it works?</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">The working of VPN is not a tough deal to understand, though it is. But, before that, you need to get an idea about the protocols or set of rules in laymen terms, used by VPN in providing a secure personal network. Let’s tell you more about it:</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">SSL (Secured Socket Layer): It uses a 3-way handshake method for assuring proper authentication between the client and server machines. The authentication process is based on cryptography where certificates behaving as cryptographic keys already stored in the client and server, are used for initiating the connection.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><b>IPSec (IP Security): </b>This protocol can work on transport mode or tunnelling mode, so that it can do its job of securing the VPN connection. The difference between the two is, transport mode only encrypts the Payload in the data i.e. only the message present in the data, whereas tunnelling mode encrypts the whole data to be transmitted.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><b>PPTP (Point-To-Point Transfer Protocol): </b>It connects a user located at some remote location to a private server in a VPN network, and also uses the tunnelling mode for its operations. Its low maintenance and simple working makes it the most widely adopted VPN protocol, further credit goes to the inbuilt support provided by Microsoft Windows.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><b>L2TP (Layer Two Tunnelling Protocol): </b>It facilitates the tunnelling of data between two geographical sites over the VPN network, often used in combination with the IPSec protocol which further aids to the security layer of the communication.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">So, you have a rough idea about the various protocols used in a VPN. We shall proceed further and see how it works. When you are connected to a public network such as internet, you can assume that all your data is flowing through a big tunnel along with the data of other users.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">So, anyone who wants to spy on you, can easily sniff your data packets from the network. When VPN comes into the scene, it actually provides you a personal tunnel inside that big tunnel. And all your data is transformed into garbage values, so no one can recognize it.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<h4>
<span style="font-family: Georgia, Times New Roman, serif;">Setting up a VPN Connection involves Three Phases:</span></h4>
</div>
<div style="text-align: justify;">
<span style="font-family: Georgia, 'Times New Roman', serif;">Authentication: In this phase, data packets are first encapsulated, basically wrapped inside another packet and some headers and other stuff are attached, all done to conceal the identity of the data packets. Now, your device initiates the connection by sending a Hello request to the VPN server, which replies with an acknowledgement and asks for the user credentials to clarify the authenticity of the user.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><b>Tunnelling: </b>After the authentication phase is finished, what we say, an imaginary tunnel is created which provides a direct point to point connection through the internet. We can send whatever data we want to via that tunnel.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><b>Encryption: </b>After we’ve successfully created the tunnel, we can send whatever information we want to, but that information is still not safe if we are connected to a free VPN service, which is also used by other people. So, we encrypt the data packets before sending them over the tunnel, thus barring any other user to peep into our packets, as he will only see some unrecognizable rubbish data flowing through the tunnel.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Say, you want to access a website, your device will send the access request to the VPN server which will then forward the request to the website in its name and receive the data from it. This data will then be transferred back to your device. And the website will think, the VPN server is the user and will find no trace of your device as the actual user.</span></div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<h4>
<span style="font-family: Georgia, Times New Roman, serif;">Uses of VPN:</span></h4>
</div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: center;">
<img alt="vpn" height="360" loading="lazy" src="http://i.kinja-img.com/gawker-media/image/upload/s--2s45DIEt--/c_scale,fl_progressive,q_80,w_800/18hwrzl3r7yupjpg.jpg" width="640" /></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><b>Remote User Access:</b> A VPN connection is used to provide direct access of a corporate network to a user who is not in the geographical coverage of the corporate network. Logically, the remote user is connected just like a normal user who is using the network within the corporate premises.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><b>Site to Site</b>: VPN is also used to provide a homogenous network environment to a corporate firm having its office locations in different parts of the world. Thus, creating an uninterrupted sharing of resources bypassing the geographical hurdles.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Other uses include, accessing those services on the internet which are not available in a particular country or region, accessing censored content or if a user simply wants to remain anonymous on the internet.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<h4>
<span style="font-family: Georgia, Times New Roman, serif;"><b>Pros and Cons:</b></span></h4>
</div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">The biggest advantage of using a VPN is the cost effectiveness it facilitates in providing a single private network in comparison to using separate leased lines which can burn the pockets of corporate firms. All credited goes to the internet, for acting as the medium for uninterrupted VPN connections.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Apart from all the good things VPN does for us, it has its weak sides too. Not having a streamlined procedure for ensuring Quality of Service (QoS) over the internet, is the biggest incapacity VPN technology has in its possession. Furthermore, the level of security and authenticity outside the private network is beyond the purview of VPN technology. The incompatibility between different vendors only adds to its bunch of drawbacks.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<h4>
<span style="font-family: Georgia, 'Times New Roman', serif;">Popular VPN services:</span></h4>
</div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">HideMyAss, PureVPN, VyprVPN, all these are well known the QoS and security they provide in their VPN connections.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">Cyber Ghost, Surf Easy, Tunnel Bear are some free VPN services you can use if you don’t want to shell out your pocket. But you’ll have to satisfy yourself with less features, download limits, or advertisements. Also, these free services can’t beat the paid services, note that.</span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<h4>
<span style="font-family: Georgia, Times New Roman, serif;">VPN on Android:</span></h4>
</div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">You can also setup a VPN connection on your smartphones running on Android OS. This allows you to access your company’s private network right on your Android Devices. VPN also facilitates the network administrator to control your device, add or delete data and track your usage.</span></div>

<span style="font-family: Georgia, Times New Roman, serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif;">VPN has so far equipped us with an extraordinary level of security and anonymity we can accomplish while sharing our confidential data over the internet. Corporate giants have always admired the ease and uniformity they can engineer in their network while using VPN. Though, it has its limitations, but so far it has outperformed our expectations and should be praised for the cost effectiveness it provides in its operations.</span></div>
