VPN Tunnel
VPN is a virtual private network. It is created by software or hardware devices on the server. Clients across the Internet can create a secure tunnel connection cable replacement and wireless connections. VPN seems to be as a local LAN. Through this network you can fully and safely, with minimal costs, connect your branch office LAN network anywhere in the world.
Many of us have a wifi router at home with an external disk or printer attached. Such a system has many advantages. You can easily share files, use Remote Desktop, put into operation a FTP server, or anything else. In large companies it is a good network matter of course. A necessary requirement is however a network access. I do not mean a situation where you're sitting in the office and you plug a cable into your laptop, that is quite a trivial matter. But, what if you need to print something on a printer located on the boss's table, update the status of goods in stock, have permanent access to a server, spreadsheets or download email from MS Exchange server? In the office, it is not a problem. Now, what if you are 1000 km away, and you have a laptop data card or are on holiday and you are limited by local conditions? Then there is VPN. In technologically advanced societies it is already in place - on the desktop icon you have a laptop with internet connection "to the company ." On the double click, wait a few seconds - and you're in business. Why not use the same comfort on a home network?
