Local Area Network
.
Typically the most common type of network
you'll encounter, a Local Area Network,
involves
connecting
computers
in
a
relatively small area. That area can be your
home, an office, or school, amongst other
locations. The devices can connect either via
an Ethernet cable or through Wi-Fi.
Wide Area Network
.
This type of network spans a large geographic area such as a city, state, or country.
The internet itself is considered the largest Wide Area Network globally, with
Wide Area Networks making it possible for smaller Local Area Networks to
connect to it. Businesses may also have a Wide Area Network to link their many
offices together.
•
Metropolitan Area Network. A Metropolitan Area Network is bigger than a
LAN but smaller than a WAN. Large corporations or government bodies use
it to link together different resources across a business.
•
Wireless LAN.
A wireless LAN works much like a
Local Area Network, but it does so
through wireless connections such as
Wi-Fi or Bluetooth rather than using
Ethernet cables.
Why Do I Need a Network?
Likely, the only network you'll come across knowingly daily is a home network,
aka a Local Area Network (LAN). Not everyone needs a home network. If you
only have one computer and no other devices you want to take online or share
resources with, there's no need for a network.
However, most people now have their own LAN setup at home with multiple
devices connected to it. It's important to know if
wired or wireless
is best for your
21
home, or a combination of both, as well as understand
how to set up a home
network
