A Short College Presentation on Star Topology

1. Star Topology Tanmay Gandhi (145) Thevar Subash (165) Jeba s ingh (333) Rushikesh Patil (356) - Members of the Group

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 c apabilities 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 S tar 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 SUMMARY
