rengasverkoita
Rengasverkoita, or ring networks, are a type of computer network topology where devices are connected in a circular fashion. Each device in the ring network is connected to exactly two other devices, forming a single path for data transmission. Data travels in one direction around the ring, passing through each node until it reaches its destination. This unidirectional flow means that if a single cable or device fails, the entire network can be disrupted.
Historically, ring networks were popular in local area networks (LANs), particularly with technologies like Token Ring.
However, the inherent vulnerability of a single point of failure has led to a decline in the
