Cisco has a great article on <a href="http://www.cisco.com/web/about/ac123/ac147/archived_issues/ipj_1-2/switch_evolution.html">layer2 vs layer3 switches</a>. One way of looking at this is layer2 switches use MAC addresses for moving packets around. Layer 3 switches use IP addresses and can perform routing functions.
A Layer 3 switch inspects incoming packets and makes dynamic routing decisions based on the source and destination IP addresses.
