Ring Networks
Ring networks are a type of network topology where each node is connected to exactly two other nodes, forming a single continuous pathway for signals through each node in a ring. Data travels in one direction around the ring, with each node acting as a repeater to boost the signal and pass it to the next node. This topology is commonly used in local area networks (LANs) and telecommunications systems, such as in Token Ring or Fiber Distributed Data Interface (FDDI) networks.
Developers should learn about ring networks when working with legacy systems, telecommunications, or network design, as they offer deterministic performance and reduced data collisions compared to bus topologies. They are particularly useful in scenarios requiring predictable data transmission, such as in industrial control systems or where network reliability is critical, though they have largely been supplanted by star topologies in modern LANs.
