other.
Routers are used to
connect LAN to WAN or MAN.
characteristics:
·
high
data transfer rate
·
less
expensive technology
·
limited
graphic area
·
security
·
reliability
WAN(Wide area Network)- A WAN is a data
communication network that covers a large geographic area i.e. one city to
another city and one country to another country. Routes are used to connect
them.
characteristics:
·
multiple
interconnected LANs
·
more
expensive technology
·
difficult
to implement than LAN
·
unlimited
graphic area
MAN(Metropolitan Area Network)- A Metropolitan Area Network is a network that connects two or more LAN or CAN(Campus Area Network) together but within a town, city or metropolitan area. Multiple routers, switches and hubs are connected to create a MAN.A MAN can create within 50 km of range.
