What is a VPN?
Lately the concept of VPN is a little distorted as there are many proxy settings that resemble the VPN, but we can say that a VPN allows us to connect via tunneling which basically consists of using a network protocol over another protocol, ie we use the local network protocol over Internet protocol, so we got to connect to certain points like we were in a local network.
Overall a VPN is typically used to access services where we blocked access, for example to other countries, but its main feature is the safe navigation or use for remote connections to work, or access content from a network Local from external Internet access.
What is a proxy?
A proxy you can define in many ways as there are several types, but broadly speaking, a proxy can say that is a computer that we place in the middle of a communication between two or more computers, as an example we can say that a computer A wants to access a resource of a computer C, we can do it directly, or using a proxy that would be a computer B to which we connect from a, and turn B connects to C, so that a is hidden for C in computer B.
Besides to hide a computer on the network, a proxy we can use to monitor traffic computers out to the Internet via proxy, for caching web pages, so if you could not access sometime in the web Internet, the server would have that stored web, and so from client computers to access the web. It can also be used to filter the type of content that can be accessed from client computers.
