What
is the difference between network LAN, WAN, and MAN
What is the difference
between LAN, WAN, and MAN. I know they sound a bit stupid, but these are the
three different types of networks that you can have. When these connections
become wireless they are renamed WLAN, WWAN, and WMAN.
|
LAN: (local area network) A group of
computers that share a common connection and are usually in a small area
or even in the same building. For
example an office or home network. They are usually
connected by Ethernet cables and have high speed connections. If it was a
wireless setup it would be called a WLAN, which would have a lower connection
speed.
MAN: (metropolitan area network) This is a
larger network that connects computer users in a particular geographic
area or region. For example a large university may have a network so large
that it may be classified as a MAN. The MAN network
usually exist to provide connectivity to local ISPs, cable
tv, or large corporations. It is far larger than a LAN and smaller than
a WAN. Also large cities like London and Sydney, Australia have metropolitan
area networks.

WAN: (wide area network) This is the
largest network and can interconnect networks throughout the worldand
is not restricted to a geographical location. The Internet is an example of a
worldwide public WAN. Most WANs exist to connect LANs
that are not in the same geographical area. This
technology is high speed and very expensive
to setup.
I hope these definitions helped as I have tried to
explain LAN, WAN, and MAN in non technical terms.
Notes:
-
Wireless LAN is WLAN. At the moment a wired connection is still always high
speed. Even though having a Wireless LAN is less mess with no cables, it
compromises on speed.
-
With
new networks popping up all the time like 3G, GSM, and GPRS, the actual end
user gets to connect directly to a WMAN which was unheard of. Most of these
networks are mobile data standards that previously or still are used on cell
phones.
