The concept of access control is all about controlling, who have access to the network, and who does not. It prevents malicious 3 rd parties (unauthorized) from associating to the wireless network. The idea of access control is very similar to an authentication process; however, those two concepts are complementary When a host machine needs to find a physical Media Access Control (MAC) address for an IP address, it broadcasts an ARP request. The other host that owns the IP address sends an ARP reply message with its physical address. Each host machine on network maintains a table, called 'ARP cache'
