Protocol
A protocol is a standardized set of rules that specify how a conversation is to take place, including the
format, timing, sequencing and/ or error checking.
Roaming
In an infrastructure network, this is when a wireless PC moves out of range of the previously connected
access point and connects to a newly connected access point. Throughout the network environment
where access point is deployed, PCs can always be connected regardless of where they are located or
roam.
SSID
A Network ID unique to a network. Only clients and Access Points that share the same SSID are able to
communicate with each other. This string is case-sensitive.
