A LAN connects devices over a small area, such as a single home, school or office building. It is usually owned and managed by one organisation, using its own cables, switches and wireless access points. LANs are typically fast and cheap to run within that area.
What is wAN?Show answer
A WAN connects devices over a large area, such as a city, country or the whole world. It often links many LANs together.
