I'm trying to understand the difference between logical and physical topologies but it's a bit confusing to me.

Cisco states these as logical topologies, but from my understanding these should be physical topologies? This is what I understand so far:

  • Physical
    • PtP: desktop directly connected to a desktop
    • Multiaccess: several desktops connected to a medium with access to each other (Cisco Ring image, how should I view this in a live situation?)
    • Ring: several desktops directly connected to each other creating a loop?
  • Logical
    • PtP: two desktops (virtually) connected to each other with intermediairy devices in between
    • MultiAccess: (don't have a clue)
    • Ring: (don't have a clue)

Could anyone help me out and perhaps explain the difference a bit more detailed? Online I can't find any useful topics. I am using the Cisco Network Fundamentals book.


I'm as far as this:

  • Physical topology is the live network with all the cables, devices, etc in between
  • Logical topology is what the network sees (desktop to desktop (PtP -> desktop, switch, router, switch, desktop)

So in the case of PtP and MultiAccess (devices connected through a switch) I understand the difference, but how does a ring topology look like for logical and phsyical topology?
