"A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building and has its network equipment and interconnects locally managed. By contrast, a wide area network (WAN), not only covers a larger geographic distance, but also generally involves leased telecommunication circuits or Internet links.
Ethernet and Wi-Fi are the two most common transmission technologies in use for local area networks." [Local area network. Wikipedia]
The LAN diagram example "Ethernet network" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Computers and Communications solution from the Illustration area of ConceptDraw Solution Park.
