They can perform regular data backups and enforce security measures, such as multifactor authentication, across all devices collectively.
Ring Topology: In ring topology devices are connected in a circular loop with each device connected to two others. Data travels in one direction (or sometimes both) passing through each device until it reaches its destination. A failure in one device can affect the whole network.
