5. DEFINITION
What is a Topology ?
The physical topology of a network
refers to the configuration of cables,
computers and other peripherals.

6. TYPES OF NETWORK TOPOLOGY
Three commonly used network topologies
are:-
Bus network.
Ring network.
Star network.
MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE
7. BUS TOPOLOGY
All computers and devices
connected to central cable or bus.
Consists of a main run of cable
with a terminator at each end.
Popular on LANs because they
are inexpensive and easy to
install.
MAIN MENU SUMMARY EXITEXERCISEOBJECTIVE
10. RING TOPOLOGY
Cable forms closed ring or loop,
with all computers and devices
arranged along ring.
Data travels from device to
device around entire ring, in
one direction.
Primarily is used for LANs,
but also is used in WANs.

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

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

ADVANTAGE DISADVANTAGE
1) Data is quickly transferred
without a ‘bottle neck’.
1) Data packets must pass
through every computer
between the sender and
recipient therefore, this makes
it slower.
2) The transmission of data is
relatively simple as packets
travel in one direction only.
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.

1) Easy to install and wire. 1) Requires more cable length
than a linear topology.
2) Security can be implemented
in the hub/switch.
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 concentrators.
