Network topology refers to the arrangement or layout of various elements (links, nodes, etc.) in a computer network. It describes how devices are interconnected and how data flows between them. Network topology can be categorized into two main types:
Physical Topology: This defines the physical layout of the network, including the placement of devices and the physical connections (wires, cables, etc.) between them. Examples include:
Bus Topology: All devices are connected to a single central cable, called the bus.
Star Topology: All devices are connected to a central hub or switch.
Ring Topology: Each device is connected to two other devices, forming a circular pathway for signals.
Mesh Topology: Every device is connected to every other device, providing multiple pathways for data.
Tree Topology: A hierarchical structure that combines characteristics of star and bus topologies.
Hybrid Topology: A combination of two or more different topologies.
Logical Topology: This describes how data flows within the network, regardless of its physical design. It focuses on the path that the data takes and how it is managed. Examples include:
**Logical Bus
