The document presents a detailed overview of various computer network topologies, including point-to-point, star, ring, bus, tree, and mesh topologies, along with their advantages and disadvantages. It discusses the importance of network topologies in optimizing traffic flow and fault detection within a network. The authors highlight the learning experience gained from creating the presentation and the significance of these concepts for students in the English department and beyond.

- 5. A network topology is the physical and logical arrangement of nodes and connections in a network. Nodes usually include devices such as switches, routers and software with switch and router features. Network topologies are often represented as a graph. INTRODUCTION Network topologies describe the arrangement of networks and the relative location of traffic flows. Administrators can use network topology diagrams to determine the best placements for each node and the optimal path for traffic flow. With a well-defined and planned-out network topology, an organization can more easily locate faults and fix issues, improving its data transfer efficiency.
- 6. TYPES OF NETWORK TOPOLOGIES
- 7. POINT TO POINT TOPOLOGY Point-to-point network topology is a simple topology that displays the network of exactly two hosts (computers, servers, switches or routers) connected with a cable.
- 8. STAR TOPOLOGY Each device is connected to a central hub in a network structure called a star topology, sometimes referred to as a star network.
- 9. 1. Less expensive. 2. Easy to install and reconfiguration. 3. Robustness ADVANTAGE: STAR TOPOLOGY DISADVANTAGE: 1. Failure of central hub will effect the entire network. 2. Performance is based on the single concentrator i.e. hub.
- 10. RING TOPOLOGY A ring network is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node —a ring.
- 11. 1 . The data transmission is high-speed. 2. The possibility of collision is minimum in this type of topology. 3. Cheap to install and expand. 4. Itis less costly than a star topology. ADVANTAGE: RING TOPOLOGY DISADVANTAGE: 1. The failure of a single node in the network can cause the entire network to fail. 2. Troubleshooting is difficult in this topology.
- 12. BUS TOPOLOGY Bus topology is a type of network topology in which all devices are connected to a single led a "bus." This cable serves as a shared communication medium, allowing all devices on the network to receive the same signal simultaneously.
- 13. 1. Coaxial or twisted pair cables are mainly used. 2. The cost of the cable is less compared to other topologies. 3. Bus topology is familiar technology as installation and troubleshooting techniques are well known. ADVANTAGE: BUS TOPOLOGY DISADVANTAGE: 1. Ifthe common cable fails, then the whole system will crash down. 2. Adding new devices to the network would slow down networks. 3. Security is very low.
- 14. TREE TOPOLOGY In a tree topology, there is one central node (the “trunk”), and each node is connected to the central node through a single path, Nodes can be thought of as branches coming off of the trunk.
- 15. 1. Itallows more devices to be attached to a single central hub thus it decreases the distance that is traveled by the signal to come to the devices. 2. We can add new devices to the existing network. 3. Error detection and error correction are very easy in a tree topology. ADVANTAGE: TREE TOPOLOGY DISADVANTAGE: 1. If the central hub gets fails the entire system fails. 2. The cost is high because of the cabling. 3. Ifnew devices are added, it becomes difficult to reconfigure.
- 16. MESH TOPOLOGY The mesh topology is a type of topology in which every device or computer is connected to every other device. Each device not only sends its signals but also receives signals from other devices.
- 17. 1. Dedicated link ensure that each connection carry its own data load, eliminating the traffic problem. 2. Mesh topology is robust. 3. Provides privacy & security. 4. Fault identification and isolation is easy. ADVANTAGE: MESH TOPOLOGY DISADVANTAGE: 1. Huge amount of cabling and 1/0 ports required. 2. Installation and reconnection is difficult.
- 18. DISCUSSION Following the completion of the topology presentation slide, we acquired knowledge about numerous topological kinds as well as presentation slide creation. We have used Google and YouTube to help us tackle a number of challenges that have been encountered. In addition to being essential for numerous step a student of English department must take, topology may serve as a reminder of the architecture and foundation of computers. The teacher of our course made all effort to aid us in comprehending the content, which may be beneficial to individuals in all walks of life.
