Difference between LAN and WAN:

WAN
|
Definition
|
LAN is a computer network that
connects computers in small areas.
|
WAN is a network that covers a broad
area using private or public network transports.
|
Data transfer rates
|
LAN offers high data transfer rates.
|
WAN has lower data transfer rates due
to congestion
|
Speed
|
80-90 mbps
|
10-20 mbps
|
Technology
|
LANs use technologies such as
Ethernet and Token Ring to connect to other networks.
|
WAN uses technologies such as MPLS,
ATM, Frame Relay and X.25 for data connection over greater distances.
|
Bandwidth
|
High bandwidth is available for
transmission.
|
Low bandwidth available for
transmission.
|
Components
|
Layer 2 devices like switches,
bridges. Layer 1 devices like hubs, repeaters.
|
Layers 3 devices Routers, Multi-layer
Switches and Technology specific devices like ATM or Frame-relay Switches
etc.
|
Ownership
|
LAN networks can be owned up private
companies or people that set it up at homes.
|
WAN are not owned up any one
organization but exist under collective or distributed ownership.
|
Data Transmission Error
|
Experiences fewer data transmission
errors.
|
Experiences more data transmission
errors.
|
Cost
|
Set-up costs are low as the devices
required to set up the networks are cheap.
|
Set-up costs are high, especially in
remote locations where set-up is not done. However, WANs using public
networks are cheap.
|
Spread
|
The network is spread to a very small
location.
|
The network can be spread world-wide.
|
Maintenance costs
|
Maintenance costs are low as the area
coverage is small.
|
Maintenance costs are high as the
area coverage is world-wide.
|
Congestion
|
Less congestion
|
More congestion
