A computer network is a network of
computers that are geographically
distributed.
A computer network is a communication
system.
4. LLOOCCAALL AARREEAA NNEETTWWOORRKK ((LLAANN))
LAN is a computer network widely used
for local communication.
LAN is a digital communication system.
In LAN, transmission channels generally
use coaxial or fiber optic cables and
special interface units and modems.
5. LLAANN AAPPPPLLIICCAATTIIOONNSS
Personal computer LANs
A common LAN is one that supports
personal computers.
LANs for the support of personal
computers and workstations have become
nearby universal in organizations of all sizes.
6. HHiigghh--ssppeeeedd ooffffiiccee nneettwwoorrkkss
New applications in the office
environment have been developed for
which the limited speeds of the
traditional LAN are inadequate.
Desktop image processors have increased
network data flow by an unprecedented
amount.
7. FFaaccttoorryy LLAANNss
The factory environment is increasingly
being dominated by automated
equipment.
To move a factory is automated, the
greater need for communications.
8. WWIIDDEE AARREEAA NNEETTWWOORRKK ((WWAANN))
A Wide area network (WAN) is a digital
communication system.
WAN connects computers over long
distances like cities, continents or
worldwide.
9. WWAANN AAPPPPLLIICCAATTIIOONNSS
Networking Environment
WANs are good for in today’s
networking environment.
Data Collection
Another important use of WANs is in
data collection.

SCOPE
• WAN is considered to be more vast and
widespread while LAN is mainly used for
private connectivity among residential
offices or a single edifice.
11. GGlloobbaall UUssee
WANs are allowing work groups to be
spread across the globe.
Network Database
WAN allows users all over a network to
access and update a single, consistent
view of data
12. CCOONNNNEECCTTIIOONNSS
• In case of LAN, Ethernet is the main
device which is used for connecting the
workstations of the computers. While in
the case of WAN, common carriers are
usually used and most people opt in for
service providers.
13. NNEETTWWOORRKK TTOOPPOOLLOOGGYY
• LAN and WAN have different
configuration.
• LAN is based on peer to peer
communication while WAN is totally
based on the client server model
14. UUSSAAGGEE
• LAN is mainly used for data and
peripheral scalability like the accessing of
scanners printers and other peripherals.
In the case of WAN, however, it may be
used to conduct business, connect with
people on a social level, share files and
data etc.
15. SSPPEEEEDD
COST OF THE NETWORK
• The cost of transmitting LAN is
negligible while the cost of WAN is
very high.
16. MMEETTRROOPPOOLLIITTAANN AARREEAA

A computer network which is spread
over a larger area than that of a LAN.
Networks that have the characteristics of
both LAN and WAN.
The main objective of MAN is to
interconnect LANs and operate
frequently at speeds very close to LAN
speeds.
17. CCOONNCCLLUUSSIIOONN
Hence, networking provides many
advantages. Some of these are listed
below:
• Networks allow efficient of resources.
• Networks help keep information reliable
and up-to-date.
• Networks help speed up data sharing.
