FTP

FTP (File Transfer Protocol) is osed to send information from one computer to another. In the case of the internet, a file is sent from a user's computer to a server. The server then responds to the data it receives. FTP uses 2 ports; 1 for administration (passwords etc) that stays open during the whole transmission, and 1 for data that opens and closes as needed. This is called 'out of band'.

FTP, when used by itself, can be a problem because all transmissions are in plain text, so anybody can read them. FTPS adds SSL or TLS encryption to FTP. 'Secure FTP' uses FTP over SSH. This will only secure the administrative and not the data port.

FTP is good for transferring large files, as it is basic and will usually transfer data directly to TCP without processing any of this information itself.

We also learned how to publish our work on 'Fetch'. This is my published site using Microsoft Word.
