What is VPN?


What is VPN?

The term VPN stands for "Virtual private network". So the first thing comes is "What is Network?"  for example if you had set data connection in your home, As well you have Modem by which you connect a Laptop, SmartPhone, Tv etc. Now if you are sending something from you are to Smart TV or receiving from Laptop to phone by wireless wifi. This is also a network called as "Internal Network". There is no link of the outer world. But when you visit a website, as you are reading this blog or if you are watching a video on YouTube "Where are these media are saved?".  These are saved somewhere in the Data Center.  No matter where are these Data Centers are Located, either USA, Germany, DUBAI anywhere you can read this article or you can watch YouTube video. Now the thing happening here is that whenever you are requesting to play the media, for example, if you want to read an on Dynamic Techs you will visit the Google and search for it. After this, Google will search in its server where is the page you are looking for is stored and your request is sent by your Router and later the Google responds from its homepage to you and now you are able to view the results. Now all the metas present on the internet either a website, an app or anything has an assigned a particular address and by this everything is possible on the internet. Now here your Internet protocol address(IP Address) go to the server and from there it gives an answer to your IP address the request you made you got an answer page for this. Here are a few Benefits as well as Demerits. The biggest advantage is that you can access the internet and this is the concept behind the creation of the internet. The disadvantage of this process is that whatever you are internet service provider is can track your data what you are looking for. Because you are making connections by IP address. This .can also keep an eye on your govt obi. If you are in an open WIFI network then anyone can keep on you and even can steal your data, we feel very glad when we got free open wifi data but you are not aware that whatever you are sending to someone the similar data is to be carried to a third person. Possibly your government can track your data. The number of times the content on the internet are restricted as of a particular country or for a particular region. Sometimes while playing a video on YouTube you get a message that "The Video is not available in your country".  This happens because when you request to play a video YouTube knows the IP address and your country and blocks the video. This is the condition at which the VPN is used. All the above problems we had been discussed can be overcome using VPN.
