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.

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 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.

The process of taking data and encoding it, usually using a mathematical formula, so that it 
becomes unreadable unless decrypted with the proper code or pass phrase.
