The document discusses various types of network topologies including star, ring, bus, tree, and mesh topologies, outlining their definitions, advantages, and disadvantages. Star topology features a central node, but its failure affects the entire network; ring topology allows high-speed data transmission but poses troubleshooting challenges. Other topologies like bus and tree are cost-effective yet vulnerable to cable failures, while mesh topology offers robustness and security at the expense of high installation complexity.

- 2. ■ Definition of Topology: A network topology is the physical and logical arrangement of nodes and connections in a network
- 3. ■ Typesof Topology : 1. Star Topology. 2. Ring Topology. 3. Bus Topology. 4. Tree Topology. 5. Mesh Topology.
- 4. Star Topology: Star topology is a network topology in which each network component physically connected to a central nodes. Advantages: ■ Less expensive. ■ Easy to install and Robustness. Disadvantages : ■ Failure to control hub will effect entire network. ■ Performance is based on the single concentrator i.e hub
- 5. Ring Topology : Ring topology is a network in which each nodes connects to exactly two other nodes, forming a single pathway. Advantages: ■ Data transmission is high speed. ■ Cheap to install and expand. Disadvantages: ■ Troubleshooting is difficult in this topology. ■ Less secure.
- 6. Bus Topology : Bus topology is a type of network in which all devices are connected to a single cable called “bus”. Advantages : ■ Coaxial or twisted pair cables are used in this topology. ■ Cost of the cable is less compared to other topology. Disadvantages : ■ If the common cable fails, the whole system will crash down. ■ Security is very low.
- 7. Tree Topology : In tree topology, there is one central node, and each node is connected to the central node through a single pathway. Advantages : ■ We can add new devices to the existing network. ■ Error detection and error correction are very easy. Disadvantages : ■ The cost is very high because of cabling. ■ If the central hub get fails, entire system fails.
- 8. Mesh Topology : Mesh topology is a type of topology in which every device or computer is connected to every other device. Advantages: ■ Mesh topology is robust. ■ Provides privacy and security. Disadvantages : ■ Huge amount of cabling I/0 ports required. ■ Installation and reconnection is difficult.
