Local Area Network (LAN)
Both an EtherNet (wire) network and a wireless network are referred to
as a Local Area Network (LAN). A wireless network does not require
hubs, switchers, or routers to include additional users on the
network. Additional wireless users are supported just by being in the
immediate physical span of the network.
A wireless LAN (or Wi-Fi network) may be configured in two different
ways:
Ad Hoc mode: Allows only for communication between different personal
computers and wireless devices, often referred to as peer-to-peer
communication.
Infrastructure mode: Required for communication with the World Wide
Web, a printer, or a wired device of any sort. In either case, this
wireless connection requires a wireless network adaptor, often called
a WLAN card.
