Most Internet software applications require both a server and a client. A server application is a program that provides some type of useful service, and a client is a program that connects to a server to access that service. For example, a Web browser is a client program for connecting to a Web server.
Your Freedom server includes many useful server applications, including Web, FTP, email, and database servers. It also provides client applications that allow your server to access and transfer data from other servers on the Internet.
