|When a hub receives a packet of data from a connected device, it broadcasts that data packet to all other connected devices regardless of which one ends up being the final destination.
||When a switch receives a packet of data, it determines what computer or device the packet is intended for and sends it to that computer only.
|Collisions occur commonly in setups using hubs.
||No collisions occur in a full-duplex switch.
|Hubs are classified as Layer 1 (Physical Layer) devices per the OSI model.
||Network switches operate at Layer 2 (DLL) of the OSI model.
|A network hub cannot learn or store MAC address
||Switches use content accessible memory CAM table which is typically accessed by ASIC (Application Specific integrated chips).
