VPN stands for Virtual Private Network. It is created on top of an existing network and allows you to combine several local computers into one network. However, the main function of a VPN connection is data protection.
When you need a VPN connection
Such a connection may be necessary if personal data or other information is transmitted over the network that should not get to unauthorized people. In addition, a VPN connection helps connect the personal computers of Internet users, who are sometimes even located on different continents. Although not very cheap, it is quite an effective solution to the issue of protecting data transmitted over the network.
Interestingly, the technology of virtual wireless networks is currently at the forefront. Its feature is the creation of a special communication channel. Any information can be transmitted through it with a high probability that it will remain inaccessible to outsiders.
To create such protection, the PPTP protocol is used. In addition, VPN technology provides encryption of critical data. As a rule, it occurs between two points that are connected by a secure communication channel.
Interestingly, if you want to hide the IP address of your computer for any purpose, then a VPN connection will also help. For example, this can be useful if a user needs to access a file on a site that prohibits access to computers with IP addresses of a certain country. With VPN, the user will remain anonymous to the system. The most that you can find out about him is the address of the VPN server. However, the probability of calculating the user is minimal, since the logs are cleaned automatically once a day. In addition, the virtual network helps to encrypt not only the transmitted information, but also the amount of traffic.
VPN in practice
You don't have to look far to evaluate a VPN. Almost everyone in modern society uses wi-fi. Why, they trumpet about him at every intersection: either a cafe with free wireless Internet, or a tram with it. It's hard not to use it. At the same time, few of the users think that their passwords as a result of working in such a public network can easily fall into the wrong hands. And there it is already not far from control over a personal computer.
Any user can establish a VPN connection on their device and use the Internet anywhere without fear of data loss.
Thus, a VPN connection is an information technology that will undoubtedly find acceptance by many Internet users in the future.
