What is a physical topology?

Answer 1

A physical topology diagram or network diagram, would show the actual physical devices on a network and how they connect to each other. This is often useful in determining how to expand a network or upgrade one.

There are several software packages that do an excellent job of producing the diagram, so it is unlikely this would be done manually. Plus, networks are dynamic enough that you would want some type of automated way of producing the diagram.

Answer 2

The way in which an abundance of computers are connected to a network with actual cables is a physical topology.
