6.  Managable Switch  Unmanagable Switch

7.  Physcal Topology The Physcal topology of a network refers to the physcal layout of the devices and cabling  Here Are The Three Primary Categories of phsyal topologies :Bus Topology, Ring Topology,Star Topology.

8. Bus Topology Coaxial Cable, Twisted-Pair wiring

9. Star Topology Twisted-Pair wiring

10. Ring Topology Coaxial Cable, Fiber Optic Cable

11.  Logical Topology The Logical topology of a network refers to the Logical paths that the signals use to travel from one point on the network to another; that is, the way in which data accesses the network media and transmits packets across it
