# Internet Library Overview

This section describes the functions in the LabWindows/CVI Internet Library. Use the client–side FTP file transfer, Telnet communication, and email capabilities to automatically send files to an FTP server, send commands to a Telnet server, or send and recieve email from a LabWindows/CVI application. Acting as a client, a LabWindows/CVI application can download updated configuration or data files from an FTP server, read data from a Telnet server, or obtain and parse messages from a POP3 server. Furthermore, you can use the functions in the Internet Library to launch the default Web browser and navigate to a specified URL or ping a machine to check if it is available.
