What is Star Topology?
In a star topology, all the devices on a network are connected to a central hub or switch. The hub or switch acts as the central controller, and all communication between devices must pass through it. Star topology is commonly used in small- to medium-sized networks, as it is easy to set up and manage.
Advantages of Star Topology:
- Reliability: If one device fails, it does not affect the rest of the network.
- Scalability: It is easy to add or remove devices from a star topology network.
- Centralized management: The hub or switch provides a single point of control for the network.
- Security: Star topologies are more secure than bus topologies, as data is only transmitted to the intended recipient.
Disadvantages of Star Topology:
- Cost: Star topologies can be more expensive to set up than other topologies, as it requires a hub or switch.
- Performance: The performance of a star topology network can be affected by the number of devices connected to the hub or switch.
- Scalability: While star topologies are easy to scale, they can become difficult to manage as the network grows large.
