Network Topologies
Network topology refers to the arrangement or layout of devices (nodes) in a network. It determines how devices are interconnected and communicate. Topologies influence network performance, scalability, fault tolerance, and cost. Types of Network Topologies 1. Physical Topology Refers to the actual physical arrangement of cables and devices. 2. Logical Topology Refers to how data flows within a network, regardless of its physical design. Common Network Topologies 1. Bus Topology Structure : All devices are connected to a single central cable (the bus). Advantages : Easy to implement and requires minimal cable. Cost-effective for small networks. Disadvantages : Single point of failure: If the bus fails, the entire network goes down. Performance decreases as devices increase. 2. Star Topology Structure : All devices connect to a central hub or switch. Advantages : Easy to set up and troubleshoot. Failure of one device doesn’t affect others. Centralized cont...
