22 Glossary
Router: a networking device that forwards data packets between computer networks, e.g. between a LAN
and a WAN (the Internet).
Switch: a networking device that connects devices together on a computer network, by using a form of
packet switching to forward data to the destination device.
VPN: a Virtual Private Network extends a private network across a public network, such as the Internet. It
enables a device to send and receive data across the public network as if it were directly connected to the
private network. A VPN is created by establishing a virtual point-to-point connection through the use of
tunnelling protocols, with traffic encryption.
Tunnel: an IP tunnel is an Internet Protocol (IP) network communications channel between two networks. It
is used to transport another network protocol by encapsulation of its packets.
