What is the topology called where all computers are connected in a circle?

The topology where all computers are connected in a circle is known as Ring Topology. In this configuration, each device is connected to two other devices, forming a continuous pathway for data. This means that signals travel in one direction around the circle, passing through each computer until they reach their destination. The ring structure allows for a straightforward data transfer process, as each device acts as a repeater, boosting the signal and maintaining network integrity.

One of the defining characteristics of Ring Topology is that if one computer or connection fails, it can disrupt the entire network, unless measures like fault tolerance are implemented. This structure contrasts with other topologies, such as the star topology, where devices connect to a central hub; the bus topology, which utilizes a single central cable; and the mesh topology, wherein each device connects to multiple others, providing multiple pathways for data. Each of these topologies has its unique design, advantages, and disadvantages, but the defining feature of Ring Topology is its circular arrangement of connections.
