Description
Device or OSI Layer
This device sends and receives information
about the Network layer.
Router
This layer can create a virtual circuit before
transmitting between two end stations.
Transport
This layer uses service access points.
Data Link (LLC sublayer)
This device uses hardware addresses to filter a
network.
Bridge or switch
Ethernet is defined at these layers.
Data Link and Physical
This layer supports flow control and sequencing.
Transport
This device can measure the distance to a
remote network.
Router
Logical addressing is used at this layer.
Network
Hardware addresses are defined at this layer.
Data Link (MAC sublayer)
This device creates one big collision domain
and one large broadcast domain.
Hub
This device creates many smaller collision
domains but the network is still one large
broadcast domain.
Switch or bridge
This device breaks up collision domains and
broadcast domains.
Router
