LAN and WAN

Local Area Network - A small network that may connect two or more systems together on a personal network connection. An example would be an internet modem connected to a wireless router. This router can send signals to any system within the designated proximity (Lets say 50 feet for example). My LAN at home is used for my Nintendo Wii, Nintendo DS, Playstation 3, my desktop computer and my Xbox 360. I have a wireless router, which grants my DS, Wii and PS3 the ability to connect without physical burden.

Wide Area Network - A vast network that may connect hundreds or even thousands of systems together on a more public network connection. An example, as Mr. Powell has described, would be the network hosted and provided by the government, shared with our school district.

This is all that was asked, so I will conclude this post.

Sincerely,
Bleed
