Types Of Network Topology

Today, we will types of network topology . What is a Network Topology? Definition of Network topology is the shape of the network . It is the physical layout of connected devices in a network. It tells us how a network will look like. Network Topology ( Definition 2) : The way in which the connections are made among all the network entities is called the topology of the network. Network Topology ( Definition 3) :Network topology specifically refers to the physical layout of the network, e.g., the location of the computers and how the cable is run between them. Network Topology ( Definition 4) :The physical topology of a network refers to the configuration of cables, computers, and other peripherals. The characteristics of a network depend upon the network topology selected. types of network topology Explain different types of network Topology Different network topologies are as follows: 1. Bus Topology 2. Ring Topology 3. Star Topology 4. Tree Topolo...
