What is Star Topology in Computer?
Star topology is a network topology in which all devices are connected directly to a central switch. The switch acts as the central hub, receiving and forwarding data packets to the appropriate devices. This topology is commonly used in home and small office networks due to its simplicity and ease of management.
In a star topology, each device has its own dedicated connection to the switch, which eliminates the risk of data collisions that can occur in other topologies, such as bus or ring. The switch acts as a traffic controller, managing the flow of data and ensuring that each device receives the data it needs.
Star topology offers several advantages over other topologies:
- Reliability: If one device fails, it does not affect the rest of the network.
- Scalability: Adding or removing devices is easy, as each device has its own dedicated connection.
- Simplicity: Star topology is easy to set up and manage, making it a suitable choice for beginners.
However, star topology also has some disadvantages:
- Cost: Implementing a star topology can be more expensive than other topologies, as it requires a switch and cabling for each device.
- Central point of failure: If the switch fails, the entire network goes down.
