Switching occurs in software.
Switching occurs in hardware.
Switches create multiple broadcast domains.
Switches segment LANs.
To create fewer collision domains
To enhance user bandwidth
To create more broadcast domains
To isolate traffic between segments
To isolate ARP request messages from the rest of the network
Hubs operate at Layer 1 of the OSI model.
They create separate collision domains.
Signals are distributed through all ports.
Layer 2 addresses are used to make decisions.
Bandwidth is shared among all connected users.
They increase the number of collision domains.
They decrease the number of collision domains.
They increase the number of broadcast domains.
They increase the amount of bandwidth available to users.

It uses data compression algorithms to manage higher bandwidth interfaces.
It is often used to provide high bandwidth uplinks for a number of lower bandwidth client interfaces.
It provides connections between network segments that operate at different bandwidths.
It uses cut-through forwarding when going from a lower bandwidth to a higher bandwidth interface.
It may require buffering frames before forwarding to the destination interface.
Forwarding method used by a switch
Time it takes for a frame to be received by a switch
Improvement in network performance from using a switch
Time delay between when a frame enters and exits a switch
Increase in the size of a collision domain from using a switch
The source MAC address and input interface pair are added to the bridging table.
The destination MAC address and input interface pair are added to the bridging table.
If no match to the destination MAC address is found in the bridging table, the frame is flooded out all other interfaces.
If a match to the destination MAC address is found in the bridging table, the frame is forwarded out the associated interface.
If a match to the source MAC address is found in the bridging table, the frame is forwarded to all ports.
