What is meant by Network Topology? Explain the various Network Topologies available to organisations.

Network topology refers to the physical or logical arrangement of nodes (like computers, servers, and other devices) and connections (like cables or wireless links) within a computer network. It plays a crucial role in determining how data is transmitted and received across the network. The selection of an appropriate network topology depends on various factors such as cost, performance, scalability, and fault tolerance. In the context of Information Management Systems (IMS) and Tourism, efficient network topology ensures seamless data sharing, real-time updates, and secure communication among tourism stakeholders like travel agencies, hotels, transport companies, and tourists themselves.

1. Bus Topology

Bus topology is one of the simplest forms where all nodes are connected to a single central cable, known as the “bus” or backbone.

• Working Mechanism: Data travels in both directions along the bus until it finds the correct recipient. Only one node can send data at a time, while others must wait.

• Advantages:

  • Easy to implement and extend.

  • Requires less cable compared to other topologies.

  • Cost-effective for small networks.

• Disadvantages:

  • Not scalable for larger networks due to performance degradation.

  • Failure of the central cable causes the whole network to go down.

• Relevance in Tourism:

  • Small tourism offices or travel agencies might use this topology for internal communication and booking systems. __________ _______ ____ ____ _______ ______ ___ _______ _____ ____ ___.
