It is the placement of the various components of a network and the different connectors usually represent the physical network cables, and the nodes represents usually the physical network devices (like switches)

It is the arrangement of network devices and nodes to form a logical or physical structure. This topology deals with network protocols that are used to control the data flow across the network. The ethernet protocol is the most common protocol used for logical topology.

It is the arrangement of a network including its nodes and connecting lines.

What are the two ways of defining a network geometry?

All data transmitted between nodes in the network is transmitted over this common transmission medium and is able to receive by all nodes in the network simultaneously.

A signal containing the address of the intended receiving machine travels from a source machine in both directions to all machines connected to the bus until it finds it intended recipient

It is a peer to peer topology.

In this topology all traffic must past through the hub or switch.

The disadvantages of this topology it is expensive and impractical for large network
