Star network and its advantages
- 1. Star Network and its advantages . 1
- 2. In the previous classes, you have learnt about Store and forward switch Cut through switch mechanisms 2
- 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 3
- 4. Star Network Topology Fig.1 illustrates the star network topology • A star topology typically uses a network hub or switch and is common in home networks 4
- 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. Advantages of Star Configuration 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) 7
- 8. Disadvantages of Star Configuration If the central hub fails, the whole network fails The cabling cost is more 8
- 9. In this class, you have learnt about Star Network topology Its Advantages Cut through and Store and Forward and adaptive switch mechanism 9
