What is a star topology?
In star topology, all devices connect to a central device like a switch or hub, making it easy to manage and isolate problems.

Why is ring topology less common in modern networks?
Because if one device or connection fails, it can break the whole network unless special measures are used.

How does bus topology connect devices?
All devices share a single communication line or cable. Data travels in both directions along this line.

Which topology connects all devices to a central hub?
✗ Incorrect
In star topology, all devices connect to a central hub or switch.
What happens if the main cable breaks in a bus topology?
✗ Incorrect
In bus topology, if the main cable breaks, the whole network can fail.
Which topology is most fault-tolerant because devices connect directly to many others?
✗ Incorrect
Mesh topology connects devices directly to many others, so it is very fault-tolerant.
In ring topology, data travels in which way?
✗ Incorrect
Data in ring topology usually travels in one direction around the ring.
Which topology is easiest to add or remove devices without affecting others?
✗ Incorrect
Star topology allows easy addition or removal of devices without affecting the rest.
Explain the differences between bus, star, and ring topologies.
Think about how devices are physically connected and how data flows.
