The document discusses different network topologies. It defines network and network topology, and lists common topologies including star, bus, and ring. For each topology, it describes the basic structure and provides advantages and disadvantages. The star topology connects all devices to a central hub, and advantages are easy installation and fault detection, while a single hub failure disables the network. The bus topology uses a main backbone cable to connect all devices, and advantages are easy connection and less cable, but a cable break shuts down the whole network. The ring topology connects each device directly to the next to form a circular path, and advantages are low cost and easy installation, but removing a device breaks the ring for all devices.

6. DEFINITION
What is a Network ?
A network is simply two more
computers that are linked together.
or

8. TYPES OF TOPOLOGY
1.Point-to-point
2.Bus
3.Star
4.Ring or circular
5.Mesh
6.Tree
7.Hybrid

9. STAR TOPOLOGY
All devices connect to a
central device, called
hub.
All data transferred
from one computer to
another passes through
hub.

10. STAR TOPOLOGY

11. STAR
ADVANTAGE
1) Easy to install and wire.
DISADVANTAGE
1) Requires more cable length
than a linear topology.
2) If any node or cable fails,
other nodes are not effected.
2) If the hub or concentrator
fails, nodes attached are
disabled.
3) Easy to detect faults and to
remove parts.
3) More expensive than linear
bus topologies because of
the cost of the hubs.

12. BUS TOPOLOGY
All computers and devices
connected to central cable or bus.
The central cable is the backbone
cable.
The devices or nodes are attached
with the bus through interface
connecter.

14. BUS
ADVANTAGE
DISADVANTAGE
1) Easy to connect computer or
peripheral to a linear bus.
1) Entire network shuts down if
there is a break in the main
cable.
2) Requires less cable length
than a star topology.
2) Terminators are required at
both ends of the backbone
cable.
3) If one node fails, other nodes
are not effected.
3) Difficult to identify the
problem if the entire network
shuts down.

15. RING TOPOLOGY
In ring topology, each computer is
connected to the next computer
and the last is connected to the
first.
Data travels from device to
device around entire ring, in
one direction.
In this way, the last node
connects to the first to
complete the ring.

16. RING TOPOLOGY

17. RING
ADVANTAGE
DISADVANTAGE
1) It is less expensive than
star topology.
1)
Adding or removing a
computer from network
effects the whole networks.
2) It is easy to install and to
maintain.
2) If any of the nodes fail then the
ring is broken and data cannot
be transmitted successfully.
3) It is difficult to troubleshoot
the ring.
