Definition – What does Topology mean?
Topology is a topological structure, refers to the physical or logical layout of a network. It defines the way different nodes are placed and interconnected with each other. The network topology may also describe how the data is transferred between these nodes. There are two different types of network topologies such as physical topology and logical topology. Physical topology highlights the physical layout of the connected devices and not, while the logical topology focuses on the pattern of transfer data between different network nodes.
Glossary Web explains Topology
Topology is an application of graph theory wherein communicating devices are modelled as nodes and the connections between modelled as lines or links between the nodes. There are seven different identified topologies, but they are not strict that means that any of them can be combined. Each topology has its own standard and uses different hardware methods, so they are not interchangeable.
The best example of network topologies are found in LAN (local area network) and a common computer network installation. All the given node in the LAN has one or more physical links to other devices in the network and graphically mapping these links in the geometric shape, which used to describe the physical topology of the network.
