single VLAN). A Router is used to separate Broadcast-Domains (we could also call them Subnets
- or call them VLANs).
So, if a router stands between all these devices, we have TWO broadcast domains.
Collision Domain:
Each connection from a single PC to a Layer 2 switch is ONE Collision domain. For example, if 5
PCs are connected with separate cables to a switch, we have 5 Collision domains. If this switch is
connected to another switch or a router, we have one collision domain more.
If 5 Devices are connected to a Hub, this is ONE Collision Domain. Each device that is connected
to a Layer 1 device (repeater, hub) will reside in ONE single collision domain.
