VPN

Virtual Private Network-Tunnels are blind relays between 2 connections on the Internet. Also called extranets and with encrypting can be called VPN's. Tunnels set up a temporary path that could enable a connection to a corporate gateway from an ISP (Internet Service Provider) winding the way around lower priority traffic.

VRLE

Value Representation Little Endian. Specifies how digital pixel values larger than one byte are represented. Some systems format two byte numbers with the least significant byte being stored or sent first (little endian). Other systems do the opposite—sending the most significant byte first (big endian). Unless the systems know how the other formats two byte numbers (i.e. pixel data), the values will be incorrectly represented.
