Internet Protocol Definitions

AP = Access Point

An access point is a device that 

connects wireless devices together 

to create a wireless network.  An AP 

usually connects to a wired network, 

and can relay data between wireless 

and wired devices.  APs operate 

on a selected channel (1 to 11) and 

broadcast their name (SSID) to allow 

connection by wireless devices.

Ad-hoc wireless network

A wireless network between two 

wireless capable devices (normally 

PCs), where no wireless access point is 

involved.

ARP = Address Resolution Protocol  

Used to determine Ethernet (MAC) 

address when a device starts to 

communicate with another. The host 

wishing to obtain a physical address 

broadcasts an ARP request and the  

device responds with its MAC address 

so further communication can be 

specifically addressed between the two.
