Topology refers to an arrangement of elements in a specific order. The types include:
1. Bus - In the bus network topology, every workstation is connected to a main cable called a bus.
2. Star - In the star network topology, there is a central computer or server to which all workstations are directly connected. Each workstation is indirectly connected to the other via the central computer.
3. Ring - In the ring network topology, the workstations are connected in a closed-loop configuration. However, adjacent workstation pairs are directly connected and other pairs of workstations are indirectly connected, passing data via one or more intermediate nodes.
4. Mesh - Mesh network topology has two forms:
Firstly, full mesh topology, in which every workstation is directly connected to each other.
Secondly, partial mesh topology, in which some workstations are connected to all the others, and some are connected only to the other nodes with which they exchange more data.
5. Tree - The tree network topology uses two or more star networks connected to each other. The central computers in star networks are connected to the main bus.
6. Signal - Signal or Logical topology refers to the nature of the paths that signals follow from node to node. In many cases, the logical topology is the same as the physical topology.
