What is client/server computing?
Most transactions that occur on the Internet are client/server based. Some
examples include:
FTP (file transfer protocol) - An FTP client program contacts an FTP server and requests the transfer of a file; the FTP server responds by transferring the file to the client.
WWW (World Wide Web) - In this case the client program is a browser. A browser requests the contents of a web page and displays the results on the user's computer.
E-MAIL - A mail client program enables the user to interact with a server in order to access, read and send electronic mail messages.
