What is Network Topology




In computer networking, topology refers to the layout of connected devices. in other words, Network topology is the layout pattern of interconnections of the various elements (ex. links, computers, network devices.)

Network Topology can be either physcial and logical.

Physical Topology refers to the physical design of a network including the devices, location and cable installation. In general physical topology relates to a core network whereas logical topology relates to basic network.

Logical Topology refers to how data is actually transferred in a network as opposed to its physical design.

Any particular network topology is determined only by the graphical mapping of the configuration of physical and/or logical connections between nodes. The study of network topology uses graph theory. Distances between nodes, physical interconnections, transmission rates, and/or signal types may differ in two networks and yet their topologies may be identical.

Types of Basic Network Topologies


Physical topologies
shape of the cabling layout used to link devices or physcial media layout of interconnected devices.

Logical topologies
way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices. The logical topologies are generally determined by network protocols as opposed to being determined by the physical layout of cables, wires, and network devices or by the flow of the electrical signals ie. MAC (Router and Switches).

Types of Networks Topologies
Bus Topology
Ring Topology
Daisy Chain Topology
Hybrid Topology
Mesh Topology
Star Topology
Tree Topology
Point to Point Topology
Server Topology
