A ring topology is a network configuration where each device (host or end system) is connected to exactly two other devices, forming a single continuous pathway for signals through each node. Data travels from device to device around the ring.Let's analyze the given statements: 1. "A host or end system is connected to the repeater." In a ring topology, data passes through repeaters (or simply the network interface of each node) as it travels around the ring. So, this statement is generally true in the context of data transmission in a ring. 2. "Each device is connected to a central hub." This describes a star topology, not a ring topology. In a star topology, all devices connect to a central hub or switch. This statement is FALSE for a ring topology. 3. "A link in the ring is shared among multiple hosts; therefore, a medium access control is required." This is true. Since data circulates and potentially multiple devices might want to transmit, a mechanism (like token passing) is needed to control access to the shared medium. 4. "When a host transmits a frame to another host, the frame moves through the repeater and link." This accurately describes how data flows in a ring topology; it passes from one node (and its repeater/interface) to the next along the links.Therefore, the only FALSE statement about ring topology is that each device is connected to a central hub.
