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.
