Question: ______ is a collection of point-to-point links that may form a circle

Answer:

A Ring Network is a collection of point-to-point links that may form a circle. In a ring network, each device is connected to two other devices, forming a continuous loop or ring. Data is transmitted around the ring in one direction, with each device passing the data to the next device until it reaches its destination. Ring networks can be used to connect devices in a local area network (LAN) or a wide area network (WAN), depending on the network topology and the type of devices being used. Ring networks have the advantage of being resilient to individual link failures, as data can still be transmitted around the ring in the opposite direction. However, they can be slower than other types of networks due to the need for data to travel around the entire ring.
