• Wireless networks (WLAN,WWAN)Wireless networks (WLAN,WWAN)

• All networks are interconnected to All networks are interconnected to allow communication with a variety allow communication with a variety of different kinds of media, including of different kinds of media, including twister pair copper wire and various twister pair copper wire and various wireless technologies .the devices wireless technologies .the devices can be separated by a few meters can be separated by a few meters (e.g.. Via Bluetooth ) or nearly (e.g.. Via Bluetooth ) or nearly unlimited distances (e.g.. Via the unlimited distances (e.g.. Via the interconnection of the internet .interconnection of the internet .

LANLAN

• LAN stands for local area network .LAN stands for local area network .

• A local area network is a peer-to-peer A local area network is a peer-to-peer or client to server method of or client to server method of networking networking

• It is used in small office It is used in small office networking .where rescores uses networking .where rescores uses minimum and a home network .(e.g. minimum and a home network .(e.g. our college labs )our college labs )

MANMAN
