5.1.7: understand characteristics of network topologies (bus, ring, star, mesh)
| Keyword | Definition |
|---|---|
| Bus | network topology where computers are each connected to a main cable or link |
| Collision | happens when two computers try to send data at the same time over the same wire or link, resulting in data having to be sent again in order not to be corrupted |
| Mesh | network topology where computers are all directly connected to each other without a hub or server |
| Node | an individual computer connected to a network |
| Ring | network topology where computers are connected so that data only flows in one direction round a circle |
| Star | network topology where computers are individually connected to a central hub or server |
| Terminator | special connector placed at the end of a bus topology network cable used to stop signals bouncing back down the bus |
| Token | special data packet passed around a ring topology network indicating which computer's turn it is to send data |
| Topology | the way that computers are arranged and connected together in a network |
