What is Network topology and types of topologies

Network topology is the arrangement of the various elements (links, nodes, etc.) of a computer network. There are two basic categories of network topologies:

Physical topologies and Logical topologies.

Physical topology is the placement of the various components of a network, including device location and cable installation, while Logical topology illustrates how data flows within a network, regardless of its physical design. Various types of topologies are:

Bus Topology:

Every computer and network device is connected to single cable.

Star Topology:

All the computers are connected to a single hub through a cable. This hub is the central node and all others nodes are connected to the central node.

Ring Topology:

Each computer is connected to another computer, with the last one connected to the first. Exactly two neighbors for each device.

Mesh Topology:

It is a point-to-point connection to other nodes or devices. All the network nodes are connected to each other.

Tree Topology:

It has a root node and all other nodes are connected to it forming a hierarchy. It is also called hierarchical topology.

Hybrid topology:

Hybrid topology uses a combination of any two or more topologies in such a way that the resulting network does not exhibit one of the standard topologies.
