A star topology is a network topology that uses a central connectivity
device as hub to connect the computers and other devices in the shape of
a star structure.
- In this topology, each individual nodes on the network communicate with a central hub that resends the message either to all the computers or nodes (in a broadcast network), or only the destination computer or node (in a switched network).
Advantages of star topology:
- Easy to install.
- Easy to diagnose fault.
- Easy to add or remove computers.
- Easy to expand.
- Failure of any node will not affect the whole network.
Disadvantages of star topology:
- The entire network fails if the central hub fails.
- More cabling is needed as compared to bus or ring topologies.
