This document discusses different types of computer networks. It defines a computer network as a system that connects multiple computers to share information and resources. It describes local area networks (LANs) that connect devices within a residence, building or campus, wide area networks (WANs) that span cities and countries, and metropolitan area networks (MANs) that connect multiple LANs within a city. It also defines personal area networks (PANs) for connecting devices around an individual and campus area networks (CANs) within a limited geographic area. The document concludes by describing different network topologies including bus, ring, star, tree and mesh.

3. INTRODUCTION
 What is network?
 A Network is a set of devices connected by
communication links.
 A node can be a computer , printer or any other
device capable of sending or receiving data generated
by other nodes on the network.

4. INTRODUCTION
 What is computer networks?
 A computer network is a system in which multiple
computers are connected to each other to share
information and resources.
[Computer network]

5. INTRODUCTION
 Applications of the Computer Networks:
 Share resources from one computer to another.
 Create files and store them in one computer,
access those files from the other computer(s)
connected over the network.
 Connect a printer, scanner, or a fax machine to
one computer within the network and let other
computers of the network use the machines
available over the network.

6. TYPES OF NETWORKS
 LAN - Local Area Network
 WAN - Wide Area Network
 MAN - Metropolitan Area Network
 PAN - Personal Area Network
 CAN – Campus Area Network

7. TYPES OF NETWORKS
 LAN(Local Area Network):
 LAN is a computer network that interconnects
computers within a limited area such as a
residence, school, laboratory, university campus
or office building.
[Local area network]

8. TYPES OF NETWORKS
 WAN (Wide Area Network):
 WAN is a communications network that spans a
large geographic area such as across cities, states,
or countries.
[Wide area network]

9. TYPES OF NETWORKS
 MAN (Metropolitan Area Network):
 MAN is similar to a LAN but spans an entire city or
campus. MANs are formed by connecting multiple
LANs. Thus, MANs are larger than LANs but smaller
than WAN.
[metropolitan area network]

10. TYPES OF NETWORKS
 PAN (Personal Area Network):
 PAN is a computer network for interconnecting
devices centered on an individual person's workspace.
A PAN provides data transmission amongst devices
such as computers, smartphones , tablets and personal
digital assistants.
[personal area network]

11. TYPES OF NETWORKS
 CAN (Campus Area Network):
 CAN is a computer network made up of an
interconnection of local area networks within a
limited geographical area.
[campus area network]

12. WHAT IS TOPOLOGY?
 Think of a topology as a network's virtual shape
or structure. This shape does not necessarily
correspond to the actual physical layout of the
devices on the network.
 The topology of a network is the geometric
representation of the relationship of all the links
and linking devices to one another.

13. TYPES OF TOPOLOGIES
 BUS TOPOLOGY
 RING TOPOLOGY
 STAR TOPOLOGY
 TREE TOPOLOGY
 MESH TOPOLOGY

14. TYPES OF TOPOLOGIES
 BUS TOPOLOGY :
 Bus networks share a common connection that
extends to all devices. Every computer and
network device connects to the same cable.
 Advantages :
 It is easy to connect machines
 Disadvantages:
 If the one cable was broken all system are shut
down

15. TYPES OF TOPOLOGIES
 RING TOPOLOGY:
 Each device in a ring network is attached to two
other devices, and the last device connects to
the first to form a circular network.
 Advantages :
 It spends larger distance than other
 Disadvantages :
 If the one machine was crashed than whole
system is shut down

16. TYPES OF TOPOLOGIES
 STAR TOPOLOGY :
 A star topology typically uses a network hub
and is common in-home networks. Every
device has its own connection to the hub. The
performance of a star network depends on the
hub.

17. TYPES OF TOPOLOGIES
 Advantages :
 If here a one machine is crashed it does
not effect other machine.
 Disadvantages :
 If the HUB is crash than the whole
networks fails

18. TYPES OF TOPOLOGIES
 TREE TOPOLOGY :
 Tree topology is a combines of star and bus
topologies and also call as hybrid topology.
 Advantages :
 Point - to - point connection for each device
 Disadvantages :
 If there is a problem with the main cable, the
entire network goes down.

19. TYPES OF TOPOLOGIES
 MESH TOPOLOGY :
 In Mesh topology all machines are connected
with each other.
 Advantages :
 Here a one machine is down that is no effect to
the other machine.
 Disadvantages :
 It is more costly than other.
