This document provides information about star topology for a computer network. It describes the key aspects of a star topology including that it has a central node or hub that all other nodes connect to. When a device needs to send data to another device, it sends it to the hub which then relays the data to the other connected devices. Main advantages are that a single node failure does not take down the whole network and it is easy to add additional nodes. Main disadvantages include being susceptible to single point of failure if the hub fails and requiring more cable length. The document discusses usages, applications, comparisons to bus topology, and concludes that star topology is best for smaller networks.

2. Star Topology- an Intro…
Star Topology consists of a central Node in
which all other nodes are connected. This
Central Node provides a Common
Connection Point for all nodes through a
Hub. In this topology, every
node(Computer, Workstation or any other
Peripheral) is connected to a central node
called a Hub or Switch .

3. - Sending Of Data to the Hub
In Star Topology when Device 1 wants to send Data to
Device 2-
Device 1 first sends the data to the hub,
Which then Relays the Data to the other Connected
Devices.
SENDING of DATA

4. Properties in Star Topology.
In a Star Topology, Each Device connects to a Central
Network Connectivity device such as a Hub, Switch or
a router. These Devices would be connected as a “star”
The other Property of a Star Topology is that failing
connection will only affect the failed devices unless
that device is the connectivity Device. This means that
in most cases a failing Device on a star will not take
down the entire Network.
Another Property of a Star Topology is that they are
easily Expandable and Scalable

5. Advantages in Star Topology
•Isolation of Devices
•Simplicity
•Whole Network will not be Affected
•Centralization
•Easy to Troubleshoot
•Easy Installation
ADVANTAGES

6. ADVANTAGES
•Isolation of Devices: Each device is isolated by the
link that connects to the Hub. It also prevents any
non centralized failure from affecting the network.
• Simplicity: Simple and Easiest Topology to
understand, to Navigate, to Detect Problems.
Simplicity in all kinds of Operations.
•Whole Network will not be Affected: It means if there is
any problem in the failure of the network whole computer
will not be affect only a single computer is affected.

7. ADVANTAGES
•Centralization: It Increases the Capacity of the
Central Hub which can help scale the Network
very Easily. It allows the check of traffic through
the Network.
•Easy to Troubleshoot: As the Dependency is High
on the Single point for Error Correction, It
Becomes Easy to Troubleshoot.
•Easy Installation: Because of the Fast and
Flexible Cable the Installation is Simple.

8. Disadvantages in Star topology
•Nodes attached are Disabled
•Single Point Failure
•Requires More Cable Length
•More Expensive
•Depends upon
capabilities of the Hub
DISADVANTAGE

9. DISADVANTAGES
•Nodes attached are Disabled: It is only dependant
upon the Central Hub so any failure it results to the
Single Node.
•Single Point Failure: As Hub Being connected to
every Computer on the Network so there is a
communication Breakdown between Computers
when Hub Fails.
•Requires More Cable Length: As Network Extends
Cable Length requires and there is Intricate between
Computers

10. DISADVANTAGES
•More Expensive: Uses Lots of Cables which makes
the Topology Expensive.
• Depends upon Capabilities of the Hub: If Nodes
see a Performance Drop as traffic to another
portion occupies to Central Hub so it depends upon
the Capabilities of the Hub.

11. Usages of Star Network
Star Topology is a Networking setup used with 10BASE-T
Cabling.
The Protocols for Star Network are usually Ethernet.
It is a Common type of Network Topology used in Homes
and Offices.
Star Topology is used to ease the Probabilities of Network
Failure by connecting all of the systems
to a Central Node.
Star Topology is used to transmit
Data across the Central Hub between the
Network nodes.
Star Topology is used in Local Area
Network.
USAGE

12. Applications Using Star Topology
Star Topology Computer fails to save the Data, if the Network has some
failure so any one of the Computer can save the Data, as it means if there is
any failure in the Network it does not affect whole Computer it just affects
one Computer. In short you can have a Backup of Data if there is a
Failure in Network.
Used in Local Area Network- Star Topology is a
example for Local Area Network as
they can share
two or more Computers
Star Topology is often used in Homes and
Offices,
It is mainly used for saving data in
Offices if some other
APPLICATIONS

13. •Comparing with Bus Topology
In Star, Devices are Connected to the Central Hub But In star
Devices are connected to the Central Cable
Star Topology is Expensive than Bus Topology
Star Topology can be Installed only for LAN but Bus Topology
can installed only for Smaller Networks. For this Comparison
Star Topology is Good

14. Conclusion for Star Topology
Star Topology is Best for smaller Networks and works
efficiently when there is
limited number of nodes .
Extra Security Features should be
added to the Hub because it is
the Heart of
Networking in Star Network.
Star Topology saves Data if there
is a failure in Network so
you can Backup data’s
and files from Computer.
In Short, Star Network is the
best Network.
CONCLUSION

15. Summary
Star Topology is a Physical Topology
Star Topology’s Common Cable is Twisted Pair Fiber
Star Topology has a Common Protocol which is Ethernet
Star Topology is used in Homes and Offices
One of the main advantage of Star Topology is when whole Network fails it just
affects one Computer
Sending of data to the Hub relays to the Other Connected Devices
Star Topology requires more Cable Length
and one of the main Conclusion or requirement for Star Topology was to have
Security to the Hub
