How does a star topology differ from a bus topology?
Understand the Problem
The question is asking about the differences between star topology and bus topology in network design. Star topology connects all devices to a central hub, whereas bus topology connects all devices along a single communication line. The response should outline the structural and functional differences between the two.
Answer
Star topology uses a central hub for connections while bus topology uses a single cable. Star is reliable but costly, bus is cheap but hard to maintain.
Star topology uses a central hub or switch to connect devices and is more reliable, scalable, and faster, but is more expensive. Bus topology connects devices using a single cable and is less expensive but harder to maintain and slower.
Answer for screen readers
Star topology uses a central hub or switch to connect devices and is more reliable, scalable, and faster, but is more expensive. Bus topology connects devices using a single cable and is less expensive but harder to maintain and slower.
More Information
Star topology is commonly used in modern networks because it offers high performance and easier fault isolation. A failure in one device or cable does not affect the others, which is a major advantage over bus topology.
Tips
A common mistake is assuming the same setup costs for both topologies. Consider the infrastructure required: central switches/hubs for star, versus a single cable for bus.
