3.1.1  What You Need to Know
The following terms and concepts may help as you read through this section.
Server
When two or more devices are connected digitally to form a network, the one that distributes data 
to the other devices is known as the “server”. A RADIUS (Remote Authentication Dial-In User 
Service) is a kind of server that manages logins and logout, among other things, for the network to 
which it is connected.
Client
When two or more devices are connected digitally to form a network, the one that contacts and 
obtains data from a server is known as the “client”. Each client is designed to work with one or 
more specific kinds of servers, and each server requires a specific kind of client. Wireless adapters 
are clients that connect to a network server through an AP.
