Mesh topology
A network where devices directly connect to each other without a central hub or switch.
Each device acts as a router, forwarding data to and from all other devices.
Requires significant setup and maintenance, but offers greater flexibility and control.
Examples: Peer-to-peer networks, wireless mesh systems.
Star topology
A central hub connects to all devices in the network.
All devices directly connect to the hub, simplifying setup and maintenance.
However, a single failure can isolate the entire network.
Examples: Personal Area Networks (PANs), LANs with a central switch.
Ring topology
A ring topology consists of a central device (ring controller) surrounded by a ring of devices.
The ring controller acts as the backbone of the network, directing data.
All devices communicate directly with the ring controller, simplifying setup.
However, the ring controller can become a single point of failure.
Examples: Ethernet rings, Token Ring networks.
Bus topology
A bus is a shared medium where all devices connect directly to it.
Devices can share the bus, allowing multiple devices to communicate at the same time.
Simple to set up, but can be limited in flexibility and performance due to shared resources.
Examples: Ethernet bus, USB bus.
Key differences:
| Feature | Mesh | Star | Ring | Bus |
|---|---|---|---|---|
| Device connectivity | Direct | Direct | Ring | Multiple devices |
| Hub/switch | Yes | No | No | No |
| Single point of failure | No | Yes | Yes | Yes |
| Setup complexity | High | Moderate | Moderate | Low |
| Flexibility | High | Moderate | Moderate | Low |
