2.  Introduction To Networking
 Types Of Networking
 Features
 Difference
 Advantage Of Networking

3. • Network is collection of computers that are interconnected to
share the information and resources.
• The computers connected with each other do not control other
computer. Network of computers can be with in the building or
span through the continents through wire or satellites.
• A computer network is made by connecting two or more
computers through a cable or wire. The computers which are
connected to each other can share the resources of each other.
• Example : One computer can access the printer of another
computer, to which it is connected. The number of printers can
be reduced using a computer network.

5. • LAN (Local Area Network)
• MAN (Metropolitan Area Network)
• WAN (Wide Area Network)
• PAN (personal Area Network)

7. It connects computer with in a building or an organization.
The speed in the lan is from 0.2 to 100 mb/sec. It is generally
owned by a single organization.
Example : Network in within your school.

9. • High data transformation rate.
• Comparatively less geometric area.
• No need of communications lines taken on leased.
• Computer of same brand are added.

10. Described as metropolitan area network it is a network between
lan and wan. It is a high speed network which can carry voice,
data and image ones 75 km distance with a speed of 200 mbps
on above.

12. • It covers rurel as well as urban areas.
• It has a data transfer rate from 34 mbps to 150 mbps.

13. It is described as wide area network. Like lan it is also not
limited within an area. It covers a large geographic area. It is
just oposite of lan and man which is limited within a class a
hall or a campus.

15. • It has nationwide and worldwide connections.
• It can connect two or more than two lans.
• It uses telephone, microwave or satelight as a transmission
medium.
• The distance between the computer connected may carry from
some miles to thousand miles.

16. 1. Personal Area Network (PAN):

17. The most basic form of computer network is a PAN. This network
is limited to a single person, which means that communication
between computer devices is limited to an individual’s work
environment.
PAN provides a network range of 10 metres from a person to the
communication equipment.
Example: Bluetooth communication.
Advantages of PAN:
PAN networks are reasonably safe and secure.
It only provides a short-range solution of up to 10 metres.
Strictly confined to a small specific area
Disadvantages of PAN:
It may make a poor connection to other networks using the same
radio frequencies.
There are distance restrictions.

19. A CAN network is larger than a LAN but smaller than a MAN
network.
This is a sort of computer network that is commonly seen in
locations such as a school or college.
This network has a limited geographical coverage, since it is
dispersed among various buildings on campus.
Example: Networks that cover schools, colleges, buildings, etc.

21. A storage area network (SAN) is a high-speed computer
network that links groups of storage devices to several
servers.
This network is not reliant on LAN or WAN. A SAN, on the
other hand, transfers storage resources from the network
to its own high-powered network.
A SAN allows you to access block-level data storage.
Example: Servers that access a network of disks.

24. Faster communication:-
Networking of computer facilitates faster communication.
Persons at geographically dispersed branches of organization
can communicate with each other through the facilities like e-
mail, UseNet, chatting, conferencing.

25. The peripherals like printer hard disk, floppy drives, scanners
etc. And software can be shared on the network. A printer
connected at one computer can be shared among other
computers in the network. The software installed on a
computer can be loaded and executed on the network.

26. You can store copy of files on many computers in the network,
if one computer fails the same file can be accessed from any
other computer on the network.
