Referred to an Ethernet concept of all
ports whose transmitted frames would
cause a collision with frames sent by
other devices in the collision domain
The devices share
the available
bandwidth.
The devices might inefficiently use that bandwidth
because of the effects of collisions, particularly
under higher utilization.
Broadcast Domains
Set of devices to which
that broadcast is
delivered
Virtual LANs (VLAN)
You can create multiple broadcast domains using a single switch
Campus switches
Access
Provides a connection point (access) for
end-user devices. Does not forward
frames between two other access
switches under normal circumstances.
Distribution
Provides an aggregation point for access
switches, forwarding frames between switches,
but not connecting directly to end-user devices.
Core
Aggregates distribution switches in
very large campus LANs, providing
very high forwarding rates.
