What is a LAN?

Your Local Area Network (LAN) is a group of computers and other devices that share a common communications line or wireless link to a server in your office, allowing you to share files and access the Internet. 

What is a WAN?

Your Wide Area Network (WAN) is the connectivity between all of the LANs at your business’s different physical locations. With the amount of data that is being transferred, sensitive information can easily be hijacked, making it imperative for you to invest in ongoing support. 

Outsource Solutions Group provides customers with over 15 years experience designing, implementing and maintaining the essential hardware and software systems necessary to extend the availability of business applications to both local and remote network users. If your local network (LAN) or Wide Area Network (WAN) is running slow, our team can isolate the issue and tell you where the performance bottleneck resides. Using layer 7 tools, we can shape the traffic on your network to provide maximum performance to applications which support core business functions.

Give us a call at 630-701-3393 or contact us via email.

What’s the difference between a LAN and a WAN?

A LAN (local area network) is a group of computers and network devices connected together, usually within the same building


A WAN (wide area network), is not restricted to a geographical location, although it might be confined within the bounds of a state or country. A WAN connects several LANs, and may be limited to an enterprise (a corporation or an organization) or accessible to the public. The technology is high speed and could be relatively expensive to implement. The Internet is an example of a worldwide public WAN.

Lastly, the protocols are different between a LAN and WAN. A LAN uses transmissions to other devices within the same network segment, whereas a WAN uses point to point transmissions between nodes of the WAN which may be separated by hundreds or thousands of miles.
