VPN, by Arnold Silver
One of the most important skills any computer user should have is the ability to use a virtual private network (VPN) to protect their privacy. A VPN is typically a paid service that keeps your web browsing secure and private over public Wi-Fi hotspots. VPNs can also get past regional restrictions for video and music-streaming sites and help you evade government censorship restrictions, though that last one is especially tricky. Arnold will share his VPN experiences with you and help to de-mystify this important topic.
