Introduction
Star Topology is a type of network layout in which all devices (nodes) are connected to a central device called a hub or switch. It is one of the most commonly used network topologies in homes, offices, and institutions.
How Star Topology Works
In a star network, each device communicates through the central hub. The hub acts as a mediator and manages the data traffic between devices. If one cable fails, only the connected device is affected; the rest of the network remains operational.
Advantages
- Easy to install and manage
- Failure of one device does not affect the entire network
- Easy to add or remove devices
Disadvantages
- Central hub failure can bring down the entire network
- Requires more cables compared to bus topology
- Cost of the central hub/switch
Conclusion
Star topology is reliable and efficient, making it suitable for modern network environments. Its centralized nature offers good performance, but the hub must be maintained properly to avoid system failure.
