FTP

File transfer Protocol is a protocol for sending files from one computer to a server or another computer.

One primary everyday use for ftp is for uploading files from a computer to a web server for display in websites.

Another use is for transferring large files (too big for email), particularly for graphic designers doing pre press work and sending files electronically to a printing company.

Another use is for transferring files from one computer to another (when they are configured to do so).

One of the problems is that it isn't particularly wysiwyg to use normally though it can be fairly straightforward. There have been concerns with a lack of security with the way files are sent using ftp.
