To Understand LAN and WAN with Examples
LAN (Local Area Network)is a group of computers and its output devices connected
via a connection wire, or wireless. A LAN only covers a small area; say a house or an
office building. For bigger connections, like buildings connected in Auckland and
Wellington, you would need a WAN.
Example
In a house you could have 4 computers, one desktop and three laptops, all connected
via wireless internet. Not only could you do that, but, you could connect the printer
up to the network as well, allowing all the computers, no matter where in the house
they were, to print to that one printer. Office buildings often do the same thing,
linking the computers in the building, or a particular floor, together and sharing one
printer between them.

be an extra workstation.

CD-ROM's. Connected to a LAN you could transfer the file easily via the LAN
e-mail or sharing files.

Disadvantages of LAN:

REQUIRES ADMINISTRATIVE TIME
FILE SERVER MAY FAIL
CABLES MAY BREAK
WAN(Wide Area Network) is a larger group of computers and output devices, as well
as input, connected via connection wires or wireless. It covers a larger area
compared to the LAN and can be used globally.
