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.

Authentication

Authentication is the process of confirming a client's or user's digital identity when

they connect to a network. Turning off authentication means disabling all security

protocols and opening your network to anyone with the means to connect to it.
