Introduction to FTP
File Transfer Protocol (FTP) is commonly used in IP-based networks to transmit files. Before World
Wide Web comes into being, files are transferred through command lines, and the most popular
application is FTP. At present, although E-mail and Web are the usual methods for file transmission,
FTP still has its strongholds.
