The full form of VPN is a virtual private network. It creates a secure connection between you and another network on the Internet. Most people use VPN primarily to access regionally blocked sites, to protect the privacy of information, and to protect themselves from being traced while browsing sensitive content.
The use of VPN is very popular nowadays. But the reason why many people use VPN today is that VPN was not born. VPN was created to securely connect business and commercial private networks.
VPN forwards your network traffic through any other network. Almost all operating systems have built-in VPN support.
How can a VPN help you?
When you connect your device to a VPN, it connects itself to another computer (server) and creates a secret passage or tunnel for your communication with the Internet. Even if your Internet Service Provider (ISP) realizes the presence of this tunnel, you will not be able to access it. As a result, the ISP will not know which site you are browsing or what data you are passing. Then if a site is blocked in your country or ISP, you can browse the site using VPN. And all this data is encrypted while using VPN.
What are the uses of VPN?
Browse Geo Restricted Content
Video and audio streaming sites will be able to browse specific content for a specific country from any country via a virtual private network (VPN). For example, you can't listen to music from Spotify site in Bangladesh. But if you want, you can also use Spotify service in Bangladesh by connecting VPN to the IP server of the US or any other country where Spotify service is available.
To keep your information safe
If you use a free Wi-Fi hotspot in a public place, your browsing data can be traced by other people on the same network if they are experts on the subject. In this case, the virtual private network (VPN) will save you. If you connect to a VPN, someone will eavesdrop on your WiFi connection, or even your ISP will only see a private network. All the data that is being passed inside will not be able to reach them.
To hide your true location
VPN will give you that benefit if you want to use the internet by keeping your actual location secret to avoid tracking different websites. You may also know that many sites in China are officially shut down (even Facebook). The Chinese use VPNs to browse those sites if needed and stay connected to the entire Internet.
To protect your privacy when using torrents
You can use VPN to avoid tracing when downloading files from torrent. Even if you download legal torrent, your ISP may slow down your connection for fear of more traffic. In that case you can avoid traces with VPN.
. . . And it could have many more applications.
Is VPN secure?
In the virtual world, the issue of security is incomprehensible. Nothing is completely safe. But many are relying on the popular VPN service providers in the market. Again, having a home-made VPN network is not a bad thing - although in many cases it may seem like "more than rent". This is not to say that there is no risk of your data being compromised from a dishonest or compromised VPN network. Many companies offer free unlimited VPN, which can be a trap if you don't understand it. So you have to do a little tweaking.
How to use VPN?
If you are very careful about your online life according to your needs, you can create and use a VPN server yourself. However, most people use various third party services to avoid trouble. You can safely use the best rated services among them. Most providers have two types of VPN plans, free and paid. Sometimes using a VPN will be enough for you free plan. And if you have to use regular for office or business, then you can take a good paid plan. Paid plans usually do not have ads and the number of servers is high and the speed is high. Also some more benefits are available in the paid plan.
Almost all VPN providers have desktop, Android, iOS app and browser extensions for virtual private network access. These are usually cross platform services. These are also very easy to use. Just go to their site and sign up.
