Apple KnowledgeBase Article on Leopard ‘Application Firewall’

Apple:

The Firewall in Leopard is an Application Firewall. This type of firewall allows you to control connections on a per-application basis, rather than a per-port basis. This makes it easier for non-experts to gain the benefits of firewall protection and helps prevent undesirable applications from taking control of network ports that have been opened for legitimate applications.
