What is VPN?? how it helps???

Question

I m little bit confused about VPN. which VPN should i choose? there r lots of apps in playstore n other places.

Answer 1

vpn stands for virtual private network
you need to chose a vpn client compatible with the vpn server you are connecting to.
vpn allows you to connect to a remote (private) network, ie your device will have an ip address and connections to other machines as if it was on the site you are connecting to

Answer 2

Virtual Private Network

Answer 3

Be wary of free VPN apps and services. Many VPNs keep a log, defeating the entire purpose of it in the first place. You'll see a reduction in speed, which is a big deal for most people.

They are super cheap, so just pay for one that has great reviews. NordVPN is what I use and it's great, despite the drop in overall speed.

Answer 4

Think of a VPN (Virtual Private Network) as one of those tunnels show-dogs run through!
Strange description yes, but a simple one.
Imagine there is no tunnel between you (maybe on a laptop in a coffee shop) and the place you want to get to (perhaps your lab at home). First, you must build the tunnel. Normally we use a VPN client for this. Once done, you have a tunnel from you to your destination.
Next we send our data through it. Just like the dog, we can only enter and exit on either side of the tunnel. This makes everything we send protected, hence the Private part. Unlike a physical tunnel (for the dogs) we must use a virtual alternative, which is encryption! This satisfies the Virtual part and ensures that only users/services with the encryption keys can access the tunnel.
Network is the clever bit. A new network is created during the tunnel creation that routes destination traffic through the tunnel. Just like the dog owner instructing the dog :)
