Describe passive scanning.
What will be an ideal response?
Passive scanning depends upon the AP "advertising" itself. At regular intervals, the AP sends a beacon frame to both announce its presence and to provide the necessary information for wireless stations wanting to join the network. This process is known as beaconing. The beacon frame provides the "pulse" of the wireless network and is an orderly means for stations to establish and also maintain communications.
