Talking about Network Topology, it is nothing but the arrangement of a network that comprises nodes and connecting lines via sender and receiver. It basically refers to how various nodes, devices, and connections on your network are physically or logically connected to each other. There are many ways to arrange the network depending upon your need and what degree of connectivity and security you want. Now, what physically and logically means here is the physical connection between the nodes and the network and the logistics of the network concerned with the transmission of data, respectively. There are various types of network topologies including Bus, Ring, Star, Mesh, Tree, and Hybrid. In this video, we're going to discuss each of these network topologies in detail with their advantages, disadvantages, usage, etc in the practical world.
