Answer:
1. B. A ring network can be wider than most topologies but not as wide as a mesh network.
2. D. In a star network topology, when one node goes down, the whole network goes down, whereas a ring network would not go down.
Explanation:
1. A ring network is a network structure in which each node is connected to exactly two other nodes, forming a single continuous signal channel - a ring. Data is passed from node to node, with each node handling one packet at a time.
A mesh network is a network in which devices (or nodes) are linked together and branch off of one another. These networks are designed to transport data efficiently between devices and clients. They assist organizations in maintaining a continuous connection across a physical place.
Mesh network topologies allow information to pass between connected nodes via numerous paths. This method improves the network's resiliency in the event of a node or connection failure. Multiple routers, switches, and other devices that act as nodes may be used in larger mesh networks. Hundreds of wireless mesh nodes can be found in a mesh network, allowing it to cover a huge region.
A computer network is a collection of devices that are linked together in order to communicate. Hubs, switches, routers, printers, computers, servers, and other devices make up the network. A network topology is a diagram of the network's connected components. There are several network topologies, including star and ring.
In a ring topology, the devices are connected in a ring-like fashion. The first device establishes a connection with the second. That gadget establishes a connection with the other. Similarly, all of the devices connect, and the last devices join back to the first, making a ring-like structure. As a result, each gadget is connected to two others.
The mesh topology has a one-of-a-kind network design in which every computer on the network is connected to every other computer on the network. It establishes a P2P (point-to-point) connection between all network devices. It has a high amount of redundancy, which means that even if one network cable fails, data will still be able to reach its destination.
2. The central site is critical in star topology; if it fails, all of the connections fail. The performance of the connection is determined by the performance of the central hub. In a star topology, two nodes may be physically separated from each other; however, they must communicate through a central node (Eboli, 2019). Ring network, failure of one node won't affect the entire network. It is simple to manage and has a low risk of collision, but it is dependent on all nodes being powered up and fully operational.
