Sometimes referred to as an FTP client, the FTP program is useful for transferring binary files and uploading text to your Web Site. While it is possible with most browsers to FTP to a site, it is generally only possible to download files from a site.
Most browsers only allow entry to anonymous ftp sites.
Most FTP software will require the user input a few basic values to be able to access a site. Sometimes this will be in the form of numbers such as 206.137.129.15 - This set of numbers is called an IP Address. These addresses tell the FTP program where to link to. Your User ID was selected when you subscribed for hosting services. Your Password is required when logging on to your site.
