Networking: LAN, WAN and VPN

Every organization that has at least one computer that is connected to the internet, has a network. A network usually consists of one or more computers connected through a device, such as a router or switch. In most cases a network has one access point to the internet.

In networking, there are a few terms that are important to know and understand. They are:
  • Local Area Network (LAN)
  • Wide Area Network (WAN)
  • Virtual Private Network (VPN)

Local Area Network


A LAN is a group of computers that are connectioned together locally. There is no access from an outside computer, but connections to the internet are permitted.


Wide Area Network


A WAN is a connection to and through the internet.


Virtual Private Network


A VPN is a secure connection from outside the LAN, through the internet. A VPN creates a tunnel that uses encryption algorythms to secure the information from outside to inside the network.

All Wolsey-Tech Inc technicians know these terms and how to integrate them into any size business. Contact us today to learn more about the ways we can help your network work for you.
