A topology is the physical arrangement of a network. In this article, we will discuss some common topologies and how they function.

A topology is the physical arrangement of a network.

A topology is the physical arrangement of a network. It determines how the network is connected and how data travels through it. Topologies can be divided into two main categories: linear and non-linear.

Linear topologies include bus, star, ring and mesh networks while non-linear topologies include tree and daisy chain (star).

Star topology

In a star topology, each node is connected to the central hub. All traffic must pass through the hub; therefore, if it fails or becomes disconnected from its power source, all other nodes will lose communication with one another.

The advantage of this type of network design is that it’s very easy to install and troubleshoot because all devices are located in close proximity to one another. You can also easily add new computers as needed by simply plugging them into an available port on your existing hubs–no need for additional wiring or cabling!

However: if something goes wrong with your main router/switch/server (or any other device), then everything else relies on those components working properly–which means there’s potential for major disruptions when something breaks down at either end (or both).

Ring topology

Ring topologies are used in token ring networks. A ring topology is also used for local area networks (LANs), wide area networks (WANs), metropolitan area networks (MANs), and campus area networks (CANs).

In a ring network, each node has two or more connections to other nodes that form the ring. Each connection is called a portion of the “ring” because all nodes have at least two physical links that connect them together into one logical path around which data can travel clockwise or …
