What is Bus and Star Topology?
In computer networking, topology refers to the physical arrangement of devices connected to a network. Two common topologies are bus topology and star topology.
Bus Topology
In a bus topology, all devices are connected to a single cable, known as a bus. Data is transmitted through the bus, and each device listens for its intended data. If two devices transmit simultaneously, a collision occurs, which can disrupt data transmission.
Star Topology
In a star topology, all devices are connected to a central hub. When a device sends data, it is transmitted to the hub, which then forwards it to the intended recipient. This prevents collisions and improves network reliability.
Comparison
| Feature | Bus Topology | Star Topology | |---|---|---| | Cable Length | Longer | Shorter | | Installation Cost | Lower | Higher | | Data Transfer Speed | Slower | Faster | | Collision Potential | Higher | Lower | | Network Reliability | Lower | Higher |
Related Questions and Answers
- What is the difference between a bus and a star topology? Answer: A bus topology connects devices to a single cable, while a star topology connects devices to a central hub.
- Which topology is more common? Answer: Star topology is more common due to its increased reliability and reduced collision potential.
- What is the advantage of a bus topology? Answer: Bus topology has a lower installation cost than star topology.
- What is the advantage of a star topology? Answer: Star topology offers faster data transfer speeds and higher network reliability than bus topology.
- Which topology is best suited for a large network? Answer: Star topology is better suited for large networks because it can handle more devices and prevent collisions.
