advantages
.

2. 2
In the previous classes, you have learnt about
Store and forward switch
Cut through switch mechanisms

3. 3
On completion of this period, you would be able
to know about

Star Network topology
Its Advantages
Store and Forward and adaptive switching mechanism

4. Star Network Topology Fig.1 illustrates the star
network topology
4
• A star topology typically uses a network hub or

switch and is common in home networks

5. 5
Fig.1 Star Network
HUB

6. In star topology, the network computers are linked to a
piece of hardware called a hub
This is a box which contains a certain number of
sockets into which cables coming out of the computers
can be plugged
Its role is to ensure communications between those
sockets
Unlike networks built with bus topology, networks
which use star topology are much less vulnerable
6

7. one of the connections can easily be removed by
disconnecting it from the hub, without paralyzing the
rest of the network
The critical point in this network is the hub, as without
it, communication between the computers on the
network is no longer possible
However, a star topology network is bulkier than a bus
network, as additional hardware is required (the hub)

Advantages of Star Configuration

8. 8
If the central hub fails, the whole network fails
The cabling cost is more
