What is the difference between a hub and a switch?

Hubs send all the packets they receive through all of their ports with no regard for the destination. The use of hubs adds unnecessary traffic on the network. In contrast, switches use Application Specific Integrated Circuits (ASIC’s) to make lightening fast decisions and direct packets to the single port that leads to its destination. Switches are often referred to as being smart since they learn and remember what devices are attached to each of their ports. They are ideal for efficiently connecting the nodes on a LAN.
