What is a 'WAN' and a 'LAN'?

Answer 1

A LAN is a local area network, meaning it is confined to one place.

LAN (Local Area Network) is a computer network covering a small geographic area, like a home, office, school, or group of buildings.
it's high speed (1000 mbps)

A WAN is a wide area network that spans large areas or distances, such as the internet that goes everywhere.

WAN (Wide Area Network) is a computer network that covers a broad area (e.g., any network whose communications links cross metropolitan, regional, or national boundaries over a long distance).
It's Less speed 150 mbps

Lan is better for connecting in local area business where as Wan is better to connect is world wide business.

In my view WANOS is a best networking service provider & also with an affordable price.
