Topology in computer networks refers to the physical or logical arrangement of different elements (nodes, links, etc.) in a communication network. It describes how devices such as computers, switches, and routers are interconnected and how data flows within the network. Topology plays a crucial role in determining the network’s performance, scalability, fault tolerance, and ease of maintenance. There are several types of network topologies, but two common ones are ring topology and star topology. Ring topology is a network configuration where each device is connected to exactly two other devices, forming a closed loop or ring. Data travels in one direction (or sometimes both directions) around the ring until it reaches its destination. This setup means that every device acts as a repeater to keep the signal strong as it passes through. One of the key features of ring topology is that if one device or connection fails, the entire network can be disrupted unless there is a provision for redundancy. It is relatively easy to install and manage
