In a era of tight government surveillance and censorship the VPN is gaining even more importance
A device that is connected to the internet (for example, your computer, router, in fact) has a unique address, an ip address. This ip address is similar to your home address, a unique description of the location of your home, making others to find. This ip address do you need because otherwise you do not use the Internet, other computers know otherwise not where they the (requested by you, such as a youtube video) back.
The disadvantage of having a unique ip address is that everything you do on the internet (websites visitors, videos, email, download, etc) very simple to lead back is to you (your computer). This is of course a large infringement on your privacy. With a VPN is all your internet traffic through a (chosen by you) conducts server making it for the rest of the internet seems to be that the ip address (and location) of that server are ip address and location.
Safe (public) networks
With the increase in the use of mobile devices with internet (latop, tablet, smartphone) is much more outdoor work or home geinternet. More and more airports, cafés hotels offer (often free) access to their network with internet access. Great useful of course, free and often fast internet but unfortunately there are drawbacks to.
The disadvantage of using these public networks is the high risk that you run. Simpelgezegd can be any person in this network very simple all your internet traffic, reading and even customize. This allows your bank account be looted, your email address/facebook etc you hacked and data stolen. Important to realize is the fact that this is not a theoretical danger, but a method that increasingly criminals really apply.
A VPN encrypted at your computer all your internet traffic, whereby another it doesn’t matter can read and can not manipulate it.
Netflix, HULU, VEVO, BBC iPlayer watching anywhere
Many well known online video services are segmental. This means that they can be viewed not from a country other than where they have contracts with the film industry. Examples include Netflix, HULU, VEVO and BBC iPlayer. If you are in the USA is you can (often free) use these services, but you live not in America then it should not. For this you can use a VPN to get around location-based resctricties. You connect to a server in the land of the streaming service (eg America). From then all your internet traffic through this server organizes and does the video service so that you are in that country and you can make use of these services.
Censorship and surveillance
There are many countries that apply internet censorship and virtually every Government monitors and logs the internet use of the inhabitants of his own (or someone else’s!). Of censorship I have little good words about, for the monitoring of internet traffic is to a certain extent also good things to say about it. Unfortunately (see also the 100-and data that Snowden has released) the surveillance not only (or perhaps “especially”) used to be for which Governments claiming to do (fight against terrorism and State security). All in all enough reason to bypass any censorship and surveillance from political Government. A VPN can be used perfectly. Your data is heavily encrypted and your location is changed. This makes your internet use difficult to control and you can escape to imposed censorship.
