Print Servers Print services allow users to print documents to a printer. Some networks are set up so that computers print to a print queue on a server. The server then handles the printing, allowing the user to continue his work even if the print job hasn't finished. A print server is especially useful in classroom and lab scenarios where multiple students send print jobs simultaneously. Mail Server Mail services allow users to send and receive electronic mail.
Electronic mail facilitates communication between members of the computing environment.
Using an e-mail package, a teacher can schedule a conference with a student or parent, send files to other departments and disseminate information to an entire student body. Communication services also let students and teachers dial-out to the Internet, electronic bulletin boards and other services such as AppleLink or Compuserve . The Proxy Server by itself does not constitute a firewall and does not eliminate the need for one.
