6. Interconnection of information technology devices within the
range of an individual person, typically within a range of 10
meters.
For example, a person traveling with a laptop, a personal
digital assistant (PDA),
and a portable printer
could interconnect them
without having to plug
anything in, using some
form of wireless
technology.
7. Network within a small
geographical area.
e.g. home, school, computer
laboratory, office building.
LAN connected devices can
share a single internet
connection, share files with one
another, print to shared printers,
and so on.
Two basic connection types
used on modern LANs
are Ethernet cables and
WLANS(Wi-Fi).
8. Ethernet WLANS
Technology used in wired local
area networks.
Ethernet connects any computer or
other electronic devices to its
network .
UTP cables are commonly used in
Ethernet LANs.
Wireless LAN links two or more
devices using wireless
communication.
WLAN allows users to move
around the coverage area.
Every component that connects to
a WLAN is considered a station.
9. New class of network.
Larger than a local area
network.
Covers the area of a single city.
Connecting of a number of
LANs into a larger network.
The two most important
components of MANs are
security and standardization.
Security is important because
information is being shared
between dissimilar systems.
Standardization is necessary to
ensure reliable data
communication.
Interconnects LANS using high-
capacity backbone technology,
(fiber-optical links).
10. Exists over a large-scale geographical area.
Connects local area networks (LANs) and metro
area networks (MANs).
WANs connect LANs across the country or around the
world.
Largest WAN in existence is the Internet.
WANs are similar to a banking system, where
hundreds of branches in different cities are connected
with each other in order to share their official data.
