Voice over Internet Protocol (VoIP) is the routing of voice calls over the Internet, or through any other IP-based network. Basically, this technology converts normal voice into a digital signal — much like a CD recording — and then wraps that digital signal with a set of IP header information, allowing it to travel across the Internet. The digital signal is reconverted back to a normal voice signal at its destination.
Short for "virtual private network," a VPN is a network that provides traveling workers or remote office locations access to an organization's central network via the internet. VPNs typically require remote user authentication, and data is often secured with encryption technologies to prevent disclosure of private information to unauthorized users.
