Can a VPN protect you from being hacked?

A VPN protects you while you are transferring information over the Internet.  

Normally when you send something over the Internet, it is launch from your computer with a destination listed in it.  It has to find its own way to that destination.  It does that by asking each server that meets if they know where the destination is.  If it does it send them to the next stop needed to reach this destination.  Kind of like if every time you asked for directions you are only told where the next turn is, never the whole path.

If the server does not know where you need to go, it makes copy of your information and send it to every server it knows.  Hopefully one of those servers will know how to get a copy of your information to its destination.  This means that there may be dozens of copies on your information on the Internet where people could steal it.

What a VPN does is sent out an empty packet.  It finds its way through the Internet like any other packet, only it keeps track of the path it follows.  Once it reaches the destination, it uses that information to set up a direct line between your PC and the destination.  A "private network" that only you can use.  It acts just the same as if there was a single physical cable connecting your PC to its destination.  No one can see what travels through that "tunnel."

Your information is then sent across that connection, and once it is done, the connection is closed down.  (It is "virtual" other than "physical".)  

It protects your information from being hacked while it is in transit.  But it does NOT protect your computer from any other form of hacking.  There are others way that they could hack your computer that have nothing to do with now a VPN works.  For example, if they can get your log on information, they can remotely connect to your PC, VPN or not.  Or they can log into your Facebook or other accounts, VPN or not.

It does add a major layer of protection to out PC.  But it does not make it 100% hack proof.

yes it can still be hacked, but its very difficult and only a few skilled people could do it

VPN is excellent and will not be easily hacked.
