Types of Networks: Data Networks
Data Networks came about
from computer applications written for business useage. The businesses soon
realized that
the standalone computers not connected to the computers in the
building were not doing the job. After realizing how much
money could be saved from using network technology, businesses
rapidly invested in networking. At the beginning of business
networking, not all computers were linked to a printer, and as a
result employees would have to save a file to a disk, load
it on a computer hooked to a printer and print the file. From
this, the name SneakerNet came about. As time progressed,
more advanced networks came about, called LAN, and WAN. In the
next two sections, you will learn the differences between
them.

Types of Networks: LAN
A Local Area Network, or
LAN, is a smaller network connecting a geographically limited area to the
internet. A LAN
usually covers 10-1000 meters. An example of this would be a
college, building or classroom. A LAN allows users to
expierience high speed internet, share files, and/or hardware(such
as a printer), and allow multiple users to access
the network at once. A LAN is moderated by a local administrator,
such as the sysadmin of your school.

Types of Networks: WAN
A Wide Area Network, or
WAN, is a large, unlimited network that interconnects other LAN's in a
different location
providing network access to many people worldwide. Some common
technologies found in WANs are: T1(E1), T3(E3), DSL, frame-
delay, ATM, and SONET.

Well, I hope you found
this document useful, and benificial to your knowledge of networking. I believe
I went into
good enough detail to make it easy enough for anyone who has some
knowledge of a computer to understand.
