|
Network, MAC
|
|
A ____ cannot partition anything.
|
Hub
|
|
A _____ can partition a collision domain, but not a broadcast domain.
|
Switch (Layer 2- Data Link)
|
|
A ________ can partition both a collision domain and a broadcast domain.
|
Router (Layer 3- Network)
|
|
-Hosts connected by a Layer 1 (Physical) device (wire)
-One Collision domain -One Broadcast domain |
Segment
|
|
-A segment, or hosts connected by layer 2 (Data Link) device
-All hosts share the same network address -One broadcast domain |
Network
|
|
Networks connected by a layer 3 (Network) device (ie Router)
- >1 Broadcast domain |
Internetwork (Internet)
