In the context below:
Any of the varieties of IEEE 802.11 wireless network begins with an access point, or AP, a network node connected directly to a wired local area network or to the Internet. The other wireless nodes, called stations, each have a transmitter/receiver working in a matching bandwidth.
When a notebook, for example, connects to the network, it broadcasts a probe request identifying itself and asking if any other 802.11 devices are within range.
If an access point within that range picks up the probe request, the AP broadcasts an acknowledgment, and the two go through whatever security or payment arrangements the network has set up. They also establish any settings needed so the notebook can talk with the rest of the network.
Who are the TWO? The AP and the probe request?
Thank you in advance.
